I'm the hiring manager for this role, which is for an IC tech lead. Please see the full job description for details, but I'm looking for someone who is comfortable leading engineering discovery and working with Product on roadmap planning within the API payroll integrations space. The most important thing in this role will be driving your own pace and taking projects from inception to completion. A successful candidate will be good at working efficiently without many hard deadlines or micromanagement. We also want someone who has strong systems design experience and good technical leadership skills. In terms of tech stack, it's mostly Python and Typescript, including nest.js

Our interview process is pretty straightforward. There's a phone screen with our recruiter, then a culture fit/qualifying interview with my boss, a technical interview with a real-world problem (no leetcode), and finally a cross-functional team interview with myself and another engineering leader at my company. We move pretty quickly and aim to keep the process respectful of everyone's time. Happy to answer any questions here! If you'd like to apply, please email recruiting [at] vestwell [dot] com with your resume.

I'm a solo founder. I built the entire product myself, got 11 fire departments paying with zero churn, and now I need someone to own engineering so I can't be the only one who does. West Point, Ranger Regiment, Yale Law, still the only developer.

What we do: Hotwash is an after-action review platform for fire departments. After a serious call, crews record what happened, we transcribe and structure it, and the hard-won lessons become searchable institutional memory instead of retiring when the veterans who earned them do. Fire is the wedge; the long game is operational learning for any high-reliability organization.

Traction: $40K ARR, 11 paying fire departments, zero churn. Raising a $1M pre-seed.

The role: Employee #1 on engineering. You own the codebase, architecture, and UX end to end, and you lead the rebuild off the current stack. You work directly with me on what gets built and why, including sitting with fire chiefs to figure out what they actually need. For the right person this becomes the CTO seat.

Who I'm looking for: A full-stack engineer who ships simple, usable products and has a real eye for design. Our users are fire crews, not power users, so the bar is "obvious to someone who's never seen it." If you care about how software feels, not just whether it works, this is your seat.

Stack: Today it's FlutterFlow + Firebase, Node, with Groq/AssemblyAI for transcription and Gemini for summarization. The rebuild target is React Native (Expo), Cloudflare Workers, D1, R2. You'd own that migration, so this is real greenfield ownership, not maintenance.

Comp: Founding equity, scaled to scope.

We're pre-raise, so cash is lean right now and grows when we close.

Email hiring@hotwash.com with a resume, link to something you've built, and one line on why this interests you.

I've tried FlutterFlow. I might even be using it now for prototyping. But with coding agents in all the IDEs, why bother?

* You are comfortable maintaining, expanding and operating a substantial chunk of a B2B SaaS platform with a high sense of ownership.

* You are happy to take on work that in a large company is divided into multiple roles, and execute it all at an excellent level.

* You are unafraid of any technology. If we need a desktop app and you haven't done one before, you will study the documentation of Electron.js and build one. If a model for predicting delivery times is needed, you will do a literature review to find the right architecture and train one.

* You have strong proficiency in any backend language or platform, with a strong willingness to dive deep into PHP/Laravel OR strong proficiency in JS/React.

* E-commerce (Shopify, Magento, other platforms, shipping carrier integrations) experience is a plus.

* Extra points if you write the initial email - however short - using your own words.

You will take a key role in shaping the product and company, with ability to make an impact and advance career limited only by your aptitude and interest.

Reach out to steve@pango.ai if you are interested or have any questions. We review applications immediately and move quickly.

We use light to control how living cells produce therapeutic proteins — optogenetic cell engineering, custom illumination hardware, and real-time ML bioprocess control — to drive down cost and scale up production of next-generation therapies.

With our technology scaling from the lab to the real world of biomanufacturing, we're now hiring a foundational software engineer to build the platform tying together our hardware, firmware, cloud, and internal tooling — high ownership over architecture and direction. This is a systems role across the hardware/software boundary (not web/SaaS), working directly with embedded, mechanical, data, and even bioprocess engineers.

Looking for: strong systems thinking; Python + one of TS/Go/Rust; cloud-connected services; comfort interfacing and debugging software against hardware (serial, TCP/IP); Linux. MS + 5 yrs or BS + 7 yrs. Bonus: Industrial IoT (MQTT Sparkplug B, OPC UA, SCADA/MES), regulated-industry data integrity (21 CFR Part 11, GAMP 5), or embedded C/C++.

focal leads inception rounds in exceptional technical founders - often before the company is obvious, before consensus forms, before datasets show a trace.

We're now hiring a founding technical leader to build the software, data, and AI systems that help us see earlier, decide better, act faster, and compound what we learn across every opportunity and portfolio company.

This is NOT an internal AI tools role. This IS a founder role. You own the proprietary intelligence layer - the system that shapes how we source, decide, support, learn, and execute.

We're looking for someone we'd back as a technical founder, but whose obsession is building the machine behind many companies rather than just one.

Details: - Carry: In Fund II and every future fund you're part of. Startup equity is one bet on one outcome. Carry is participation in every company we back, across every fund, for as long as you're here. Grants layer over time and your upside compounds. Exact % shared with qualified finalists. - Cash comp: Commensurate with experience and impact (~$175k-$250k base) - Additional benefits: 100% paid healthcare, 401(k), 6 weeks PTO, 3 months paid parental leave - Budget: For tools, compute, office needs, and experimentation - Setup: High trust, low process. You have wide autonomy over how you work, we care first and foremost about impact.

Apply: Send hiring@focal.vc your LinkedIn (and X if you have it) along with the thing you've built in recent months you're most proud of and why. We look for evidence of taste, systems thinking, and judgment.

Full post: hiring.focal.vc

L2 Labs is a brand new applied AI lab building machine intelligence for data integration and interoperability. We're fast growing: we closed a pre-seed funding round, established partnerships with Cornell and NYU, and secured a large enterprise customer in less than 3 months. We are a team of hard-working researchers and engineers who are obsessive about intricate, greenfield data problems - we love whiteboarding, spinning up experiments, ordering pizza, and suddenly it’s 2am and we've actually solved something. We build impactful products + publish in A* research venues.

We are currently seeking Founding Senior SWEs, with very meaningful upside in the form of a generous equity package + working alongside skilled engineers and PhDs from top universities. To learn more/reach out, email me at andrew@l2labs.ai. We are able to sponsor international candidates.

I'm building an AI-native operations tool for private mortgage lenders. MVP targets two workflows that eat servicing staff time: NSF collections follow-up and renewal management. I run a Canadian private lender as my day job, so the product is built against a real shop with real data and real users. Self-funded. No VCs, no board.

The data model is locked (20 tables, multi-tenant by lender_id, idempotent CSV imports, append-only event log). Wireframes in progress. Hiring one engineer for the full ~6-month build via a paid bake-off: $5k flat for ~1 week of work, 2-3 candidates in parallel, winner takes the engagement. Losing candidates get paid in full and keep their work.

Trial scope: CSV loan tape import with idempotent upsert + audit, one case detail screen, one LLM call classifying a borrower email reply with structured output, activity log driven by case events. Stack is contractor's choice — Postgres required, Next.js + TS or Python + React expected.

Looking for senior generalists with real production LLM experience (structured outputs, evals, failure modes — not side-project tier) and strong relational data modeling judgment. Opinions you'll defend in writing.

Email: info@readifinancial.com

with: one paragraph on why this interests you, 1-2 links to shipped work involving a real schema + LLM in production, your rate and availability, and one question about the project. No cover letters.

Thank you in advance.

We work with robots that run biology experiments. The robots are accurate, but programming them by hand takes so long that most labs don't bother. So we wrote a compiler and visual editor a scientist can use. They describe their protocol in plain language, we parse it into a structured format, and compile that to optimized code. Our end goal is to build the infrastructure for autonomous science and a centralized cloud lab. Short demo: https://tinyurl.com/mrx63phb

The team is three software engineers, an automation engineer, the founders, and soon a designer. The codebase is one monorepo containing an OCaml compiler, Python backend services, and a TypeScript/React editor. The challenges come in the form of eliciting scientific context and tacit knowledge and in the fact that a protocol has to deterministically run correctly.

We are looking for at least 3 years of experience. OCaml isn't a requirement, just a willingness to learn it. Nice if you've done DSLs, compilers, life sciences or lab automation, an ML-family language, or LLM parsing and evals.

We're hiring an Analytics Engineer to help power our future. This is a really greenfield project where we need to define the data models that fuel all reporting, analytics, and ML/AI going forward. We do 'freight audit' - we save our clients money by making sure all their logistics spend is correct and as agreed.

At Trax, our data infrastructure is in the middle of a real transformation. We're building the data foundation that will power our next wave of AI features, and we need someone who can own that work end-to-end. This isn't a "run queries and make charts" role.

You'll be:

- Designing and maintaining data marts in dbt + Snowflake

- Building customer-facing dashboards that integrate into our platform

- Bridging the gap between engineering, business ops, and client teams

- Running ad-hoc analyses that drive real decisions

- Shaping how our data platform evolves alongside our AI/ML capabilities

What matters most to us:

- Deep data modeling knowledge (domain logic, not just syntax)

- Advanced SQL; dbt and Snowflake experience is a big bonus

- Strong communicator who translates between technical and non-technical worlds

- A learning mindset; genuinely non-negotiable for us

We're a small, close team. You won't disappear into a large org. You'll work directly with leadership, partner with Solutions and Sales, and have a real voice in how we build. If you thrive on ownership, are energized by complexity, and want to see the direct impact of your work, let's talk! My email and linkedIn are in my profile.

Relevant builds a data platform that helps safety-net healthcare providers deliver better care using data from their electronic health records. Our customers are non-profit clinics called Community Health Centers. You can read more about them, us, and the roles on our jobs page: https://relevant.healthcare/jobs/

We're a small team (~25 overall). We're bootstrapped (no external capital whatsoever, VC or otherwise) and profitable. We've got a modern tech stack (Rails, Typescript, React, GraphQL, d3) and a healthy approach to both tech debt and work/life balance… and we’re also a very nice group of people that get to work on interesting problems for some of the few unimpeachably good actors in healthcare!

We build AI-assisted auditory training for people with hearing loss. Our product is live, in clinics, and growing internationally.

Backend Engineer: Postgres-heavy work on Supabase: PL/pgSQL functions, pgmq queues, Deno edge functions, billing and cron systems. You like databases enough to enjoy writing triggers and RLS policies, and you want to own systems end-to-end rather than just ship tickets.

Quin is an agentic platform to (finally!) solve personal finance for people. It is a consumer-focused company.

https://iamquin.ai

I spent 13 years in private banking and have been working on Quin alone for about 15 months. I built 6 different prototypes to test different approaches. I've spent the last few weeks working with testers on the latest version and solidifying GTM. I need someone to take over engineering with a focus on building the backend and data layers that will support our agentic approach to personal finance.

Georgetown. UCLA (MBA). Ex-JPMorgan.

Traction: Prototype with testers

The role: You're the first engineering hire. This is about shipping the workflows that will become the product that users will trust and the data layer that can support an agent in the future.

You'll own backend architecture decisions from day one. Contract-first development (TypeScript contracts repo as source of truth), FastAPI, Supabase/Postgres, Groq for LLM inference. The stack is clean and the codebase is small.

Who I'm looking for: A full-stack engineer with a preference for backend. 5+ years backend engineering; Python / FastAPI preferred. Strong data modeling instincts — you've designed schemas that had to scale. Experience with multi-tenant data architectures. Comfort operating without process. Finance domain familiarity a plus, not a requirement. Comfort and experience using AI tools and incorporating new ideas quickly.

For the right person, this is an opportunity to take a CTO/co-founder role and define the full technical path.

Comp: Salary post-raise and meaningful equity. TBH, finding this role (either version) will be important for rasisng capital given that I do not have a technical background and fintech is complicated by regulations. I'm ok with part-time in the meantime if that's what it requires.

Email quin@iamquin.ai with the primary reason this interests you and the top two reasons why you should be considered (don't worry about a resume at this point).

Aquabyte is on a mission to revolutionize the ocean sustainability and efficiency of aquaculture. By making fish farming cheaper and more viable than livestock production, we aim to mitigate one of the biggest causes of climate change and help prepare our planet for impending population growth. Aquaculture is the single fastest growing food-production sector in the world, and now is the time to define how technology is used to harvest the ocean for generations to come. Through custom underwater cameras, computer vision, and machine learning we are able to quantify fish weights, detect sea lice infestations, and generate optimal feeding plans in real time. Our product operates at three levels: on-site hardware for image capture, cloud pipelines for data processing, and a user-facing web application. As a result, there are hundreds of moving pieces and no shortage of fascinating challenges across all levels of the stack.

We are a seed stage startup building Tabular Foundation Models (TFM). This is an emerging space with huge potential.

LLM's like Claude take text as input and produce text. Model's like nano banana take text as input and produce images. Tabular Foundation Models take rows/columns as input, and produce predictions.

The world is sitting on huge amounts of structured data that isn't being used to its potential. Making predictions is hard. Today, most folks are building, training, maintaining their own models. A bit like you'd need to have done back in 2019 with LLM's.

We want to change that. We're looking for an early career Field Engineer to help build out demos, docs, resources, integrations as well as driving product adoption directly with customers. Someone who is passionate about building, has shipped real software (or predictions), has experience with Python and data science fundamentals.

If you're looking for something a bit different than just "hands on keyboard" engineering, and enjoy business as much as tech, this could be for you.

Feel free to reach out at aaron.stillwell@neuralk-ai.com

Hiring our first Radar AI Engineer to own the full pipeline end-to-end: raw FMCW/MIMO signal in, deployed embedded model out (ONNX, TensorRT, edge TPUs). Real hardware. Real customers. Privacy-first by design.

Looking for: MSc/PhD in ML / EE / signal processing; strong PyTorch + Python; embedded deployment experience; Rust or C/C++ a plus. EU-based or NL-visa-eligible (we sponsor highly-skilled-migrant + 30%-ruling for the right person).

Process: first call in 5 days, decision in 3 weeks. Founder-led, no multi-month limbo.

Apply: https://husense.odoo.com/jobs/radar-ai-engineer-6 or email radar-ai-engineer@mail.husense.io with the one project you're proudest of.

Tech stack: Vue/React, TypeScript, Three.js/WebGL/WebGPU, TinyBase, Django.

You can help us solve problems like: - Making 2D and 3D annotation workflows faster, more precise, and easier to use - Designing point cloud tiling, autosave, undo/redo, review, filtering, and issue-tracking workflows that hold up under real labeling operations - Improving performance where milliseconds matter: rendering, local state updates, preloading, and geometric operations - Shaping API contracts, data models, permissions, background jobs, and operational tooling as the platform scales

By fraudulent I mean: fake resumes, names stolen from real developers who work at well-known companies but either don't have a linkedin/portfolio or do have a linkedin/portfolio without a profile picture. So easily impersonated by a scammer.

It is a real shame, but this thread is now being scraped by plenty of other sites and bad actors.

Inbound hiring for remote teams is basically cooked at this point, signal is completely hidden in the noise. Curious if anyone else has had this experience or if it's just me?

But no, it's just a performance. The director can claim they're behind on projects because they don't have enough staff, but everyone they interview isn't qualified (because the interviews are impossible and nearly everyone trips up)

I started seeing this pattern recently.

The companies that are serious move fast. A chat with the hiring manager. A couple technical interviews, maybe on-site for 2 hours. A chat with someone higher up. Done, offer made.

On an unrelated note, your localias project is really cool! Going to give it a spin tonight.

As a job seeker, I see the chaos from my side of the table, I feel like its well known and discussed.

The other side of the table however, the recruiters and hiring managers, I want to understand this more. I feel like I could assume the struggles your having, but I would love to see more discussion around this.

> Commenters: please don't reply to job posts to complain about something. It's off topic here.

LinkedIn is doing nothing to stop the fraud at this point. There's almost no way to tell if you're talking to a real person unless you meet with them personally at their office.

Small stealth team in the property management space, building AI agents that run real operations, where agents and humans work as one team rather than as user and tool. Funded, profitable, fully remote, competitive comp.

We want a senior backend engineer to own a client facing use case end to end: build the backend tools and workflows our agents call, handle the jurisdiction and client specific extensions, and talk to the client directly. Pull requirements, explain the tradeoffs, own the relationship. Take messy real world problems, turn them into something agents can actually use, then keep it alive in production.

You're probably a fit if:

- you've shipped serious backend systems in production

- you can hold your own on a customer call

- you've run LLM agents in production, or you'll ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call

Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain and LangGraph, prior customer facing or operator background.

We care more about what you've built and can build than a checklist, so skip the skills inventory and tell us about something hard you shipped.

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.

Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.

We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.

In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.

We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~500). Now we’re scaling the platform.

Opaxa is the AI agent platform that runs restaurant back-office operations. Not another dashboard — agents that take the work off the operator's plate and act: build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, draft the review reply. The operator approves what matters; the rest gets done.

The unfair part: the founder owns and runs a 40-location restaurant company with over 750 employee's — so Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Deep domain expertise is built in, and your work runs in real restaurants immediately, not after a six-month hunt for a design partner. Well-funded.

A working prototype is already built. Now I'm hiring a founding full-stack engineer to take it from prototype to production: own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), set the technical bar, and grow the team behind you.

You'd work directly with me — I own product, customers, and the domain; you own the AI and the build. We'd be hiring additional engineers and account managers within the first year.

You're a fit if you: - have shipped agentic systems to production — plan-and-act, not chatbots or wrappers - are a strong full-stack builder (Python and/or Node, Postgres, real infra) - use the latest AI tooling (Claude Code / Cursor) as your default want to own a whole product as the first engineer, and eventually lead

Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, integrations across the restaurant stack.

To apply: email me at colton@opaxa.ai with the most impressive agentic system you've personally shipped — what it did, what you owned, and what made it hard — plus your resume or links. I read every one and reply. Please write it yourself; if it's clearly AI-generated, I'll pass.

Our product helps everyone make better legal decisions by better understanding the law. About one-third of important U.S. law is not accessible via ChatGPT or Claude. Much AI-generated legal analysis is wrong. We are building one of the largest collections of U.S. law in existence and using AI to make it make sense.

We are a seed-stage start-up, still in stealth (but already with an acquisition offer!), backed by tier-1 VCs and many of the most prominent experts in legal technology. We are working with several of the best law firms in the world. We have strong customer demand and need people to help us fill it. We are committed to improving access to justice.

We are hiring a small team of extremely talented, motivated, intense, and interesting people to solve the most difficult and important problem in legal tech: high quality answers to legal questions. Expect market-leading compensation, including meaningful equity ownership. Please send your resume to contact[at]ashmere.com.

Hey HN! I'm Ian, one of the founders of Root Managed Services.

Root Managed Services is a managed IT services provider focused on helping businesses keep their infrastructure stable, secure, and running day to day.

We're hiring a network engineer who is excited to help with day-to-day NOC operations, client infrastructure support, alert triage, troubleshooting, and keeping systems online. This is a hands-on role for someone who enjoys digging into network issues, server alerts, firewalls, tickets, documentation, and the operational details that keep businesses running.

Root Managed Services works with small and growing businesses that need reliable IT operations without building a full internal team. That means our work spans networking, servers, workstations, monitoring, ticketing, backups, security, and client communications. We’re looking for someone who can help us improve our NOC process, respond to issues quickly, and build better operational workflows as we grow.

Stack / tools: Windows Server, Linux, firewalls, switches, VPNs, RMM tools, ticketing systems, monitoring/alerting, Microsoft 365, Active Directory, DNS, DHCP, VLANs, TCP/IP.

Applying: email me and let me know why you want to work with us.

The world doesn't need another ERP. CoPlane is building the Agentic Orchestration platform that enables enterprises to orchestrate intelligent processes across their existing systems. Founded by ex-Stripe/Segment product and tech leads, we're changing how businesses operate their backoffice - helping them scale intelligence not headcount.

We're looking for an exceptional product engineer to grow our small team of engineers that include ex-founders, open source contributors (authors of neovim and neverthrow), and architects of petabyte-scale data platforms.

We are looking for someone that wants to own product features end to end (Python + Typescript/React) but is particularly spiky on frontend and UI. You'll build a platform for billion-dollar enterprises solving their hardest, most mission-critical automation problems.

If you're excited about working at the nexus of data, automation and AI, and want to make a significant impact in an early, well-capitalized startup with large enterprise design partners, we'd love to hear from you.

Roles: Product Engineer.

ClickHouse is a popular, Open-Source OLAP Database. We are ClickHouse Inc, the company behind the database aiming to build the best in class real time data warehouse.

What we are looking for:

Distributed Systems / Cloud Engineers to build

    - AutoScaling Systems for a Cloud Database

    - A Distributed Caching Layer on top of S3 [0]

We also maintain our own ClickHouse based Data Infrastructure. Bonus points if you've worked on auto-scaling or other data-driven forecasting challenges in the past.

    Can work in a fast moving scale-up environment. Proactive and hands on.

    You must be independent and self-organized.

    Database SRE / Cache Operations experience

    Go, Kubernetes, Distributed Systems in general

    You will need to be able to do On-Call - debugging production infra, db or cache issues

    Low-level database programming (C++, ClickHouse) - This is crucial for the cache.

[0] https://clickhouse.com/blog/building-a-distributed-cache-for...

Today we use ML to make data warehouses and spark jobs more efficient. We're hiring staff ML engineers to train models that can understand how much compute a job needs, how it scales to larger machines, whether a machine can run more jobs, and so on; and staff infra engineers to take those models and deploy them on real-world production systems.

We're also looking for FDEs who can help us talk to users and run pilots. This is a pretty technical role (you need to be able to do data analysis and debug in prod) that's also user-facing - it should be a good fit for a former (or future) technical founder.

Jefit is a profitable fitness-tech company — 15+ years in market, no funding pressure, no enterprise red tape. We're hiring an experienced Android engineer to drive the Android side of our Adaptive Plan — a mesocycle-driven progressive-overload engine — end-to-end alongside our CTO. You'll see your code in front of millions of users every day.

What we care about (more than years on a resume):

You've shipped real Android products to Play Store — solo side projects count

Kotlin + Jetpack Compose + Coroutines, or you're actively learning them

AI-coding-assistant fluency is non-negotiable — Claude Code, Cursor, Copilot integrated into your daily workflow, not a name-drop

Offline-first / Room / SQLite mindset (we run in real gym environments where the WiFi is bad)

Extreme ownership end-to-end — feature, ship, polish, debug, repeat

We bias toward fast learners who already use AI to ship faster, over senior engineers stuck on a 2018 stack.

In-office in Santa Clara, CA. US work authorization required (no sponsorship).

TypeSafe AI (https://typesafe.ai/) is a well-funded stealth mode company making a new class of AI models which enable a reliable way to embed composable intelligence into traditional software, founded by a co-author of ChatGPT/RLHF/GPT4 (answering the questions "If AI is so smart, why are we barely automating any work? Why does today's AI always need a human-in-the-loop?").

We're especially looking for people to join our Synthetic Data research team - no previous data experience needed (synthetic or otherwise). We need strong engineers who care deeply about the end use cases and whose instincts are to NOT trust LLMs blindly and look at the reality of their generations (much more investigator in the spectrum of investigator vs optimizer).

We're a fast-growing custom & private loyalty platform powering programs for household-name brands. Small, fully-remote team across the US and Europe.

We want a detail-obsessed, autonomous mid-to-senior engineer (~5–10 yrs) to investigate customer problems, drive integrations end to end, and own the specs that make them work.

You will use AI to its fullest, but will keep a very close eye on whatever that AI produces. As such, this role is less about coding, and more about figuring out what to build, how that best fits into the system, and why things are as they are, debugging edge cases, anticipating failure modes, talking to people, and plain old debugging.

Tech-wise, we're running on Golang, and using custom database engine on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap'ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We're doing that in production. Zero lines of React, few third-party dependencies carefully vetted, every line of JavaScript manually written, and we render HTML server-side like it's 2005.

You: detail-oriented to a fault, self-motivated about investigation/debugging work, comfortable spoken English for client calls, available 9am to noon in New York time.

We are straightforward, driven, personal, and a little messy. We all care, and we expect you to care too.

Veedma is a telehealth practice for men's hormonal and sexual health. We treat low testosterone, ED, and vitamin D deficiency in men 18 and up, fully online. Cash-pay subscription covers consultations, lab panels twice yearly, prescribed medications, and unlimited messaging. Clinically Enclomiphene-only; we don't offer testosterone replacement therapy.

Founder-led: an MD urologist (CEO) and a software CTO (ex-Yva.ai, acquired by Visier). The platform is AI-native by default: both founders code in Claude Code every day, production calls OpenAI's API from Python, Akute is the EHR, Stripe handles billing.

Two founding seats, both reporting to the founders directly:

* Founding Product Engineer ($160-200k + equity). Python/Flask/Postgres/Celery. Own patient flows, EHR and billing integrations, internal clinical tooling, and the in-product LLM layer. 7+ years shipping production web apps, most of them in healthcare. Apply: https://app.dover.com/apply/Veedma/8f5e6d01-75f1-46a8-b5b7-9...

* Founding Growth Engineer ($150-190k + equity). A builder who happens to do growth. No paid budget, no agency. You ship landing pages, scrapers, creator outreach pipelines, referral loops. 7+ years in organic / partnerships growth, most of them in healthcare. Apply: https://app.dover.com/apply/Veedma/d39d76d3-e968-407c-b268-0...

Bar for both: Claude Code is your primary tool (6+ months daily, you write skills and wire up MCP servers). Healthcare in your background and where you want to stay. AI-native, not AI-curious.

Both: remote US, async-first with US-hours overlap, full-time, 1.0-1.25% equity. All roles: https://app.dover.com/jobs/veedma

Frisson Labs is building AI players that play like Discord friends. The hard part is making them respond with low latency, persistent personality, voice timing, and actual game competence: understanding what is happening, deciding what to do, and executing in real time.

Open roles:

- Founding ML Engineer - General: own the full stack for how AI companions play games: game-state understanding, learned policies/controllers, world models, action representation, MLP/policy heads, memory, evals, data pipelines, inference, and product iteration. Strong fit if you have shipped applied ML systems and want to own messy model behavior all the way from research prototype to live gameplay.

- Founding ML Engineer - Audio/Speech: explore and ship low-latency speech systems for real-time play: duplex/streaming voice models, speech understanding, turn-taking, interruption handling, latency/quality tradeoffs, prosody/emotion, and conversational evals. Strong fit if you have deep audio/speech ML experience and care about making voice feel socially present during gameplay.

Comp: - ML Engineer roles: $150K-$200K + 1.0-2.0% equity

Apply: email founders@frisson-labs.com with the role in the subject, plus your resume/GitHub/research/portfolio and a short note on why AI companions + gaming interests you.

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

We've just launched Speckle Intelligence: ask your project models anything, trust the answer, and generate client-ready deliverables in minutes. 23 people, open-source core, enterprise tier on top, post-Series A. Repo: github.com/specklesystems

We're hiring our first Head of Delivery to own the enterprise post-sale motion: turning pilots with general contractors, owners, and large service providers into expanded production deployments. Forward-deployed role (think Palantir FDE, not SaaS customer success) - you sit inside the customer's real decision problem, make "trust the answer, take the action" true on their actual data, and feed what you learn back into product. We measure impact and not closed ticket counts.

Good fit if you've delivered technical/data products into heavy industry (AEC, construction tech, infra, or similar) and can read an enterprise's problem without a spec. AEC background a strong plus, not required. Comfortable with messy data and ambiguous orgs.

Apply: d@speckle.systems

Tenera (https://trytenera.ai) is building the product decision layer for agents and humans, backed by a top tier VC (announcing soon). We help teams validate what they build across the entire software development lifecycle, grounding AI personas in real user behavior and business context, then proving them out by replaying past product decisions.

We are a small, exceptionally talented team (ex-Amazon, Nvidia, Uber, Stanford, CMU) hiring our first engineer. We work onsite in SF five days a week (open to relocation for the right person) and offer meaningful founding equity.

This is an unconventional role. We want an "agent-native" engineer. If you are still writing every function by hand, this isn't for you. You will orchestrate multiple coding agents in parallel, managing worktrees, concurrency, and shared context, while owning the architecture decisions that matter most: big data pipelines, schema design, system tradeoffs, and evals.

Requirements: 3+ years shipping full-stack apps, comfortable with LLM infrastructure and tracing, fluent with git worktrees and isolated workspaces, and strong product taste. Active GitHub contributors preferred.

Interested? Email: suzie@trytenera.ai

We secure the SaaS apps companies actually run on: M365, Salesforce, and hundreds more. You’d be on the Threat product team working full-stack. That means browser extension code (content/background scripts, manifest v3, message passing), backend services chewing through millions of events, and the data pipelines feeding our detection engine. One day you’re in TypeScript debugging why a content script won’t capture form submissions on some vendor’s weird SPA. The next you’re in Python fixing a Kafka consumer that’s falling behind. Sometimes you’re in Rust optimizing a hot path in the telemetry collector.

Big current focus is shadow AI, i.e. catching when employees paste sensitive data into ChatGPT, Claude, or whatever LLM showed up this week. You’d build the systems that detect it.

Looking for ~8+ yrs experience, real browser knowledge (DOM, event loop, SPA routing, CORS, not just “I used React”), prior browser extension work, strong TypeScript, comfortable in Python, willing to write Rust, plus data-at-scale chops (event streaming, Postgres, Elasticsearch, Kafka). Bonus: AI security (prompt injection, exfiltration), detection engineering/SIEM, or security tooling.

ParadeDB is a Postgres extension that delivers state-of-the-art search in Postgres. Our customers, including Alibaba Cloud, BILT Rewards, Modern Treasury (YC S18), and many others, rely on us to deliver the performance and feature set of dedicated vector databases/Elasticsearch natively in Postgres, simplifying their stack and day-to-day operations.

If you like systems, this might be for you. We're a team of 10, a Series A company based in SF but distributed across North America. We're hiring for database internals work (e.g., building the database in Rust) and distributed systems work (e.g., building the database-as-a-service platform in Go).

We're open-source at https://github.com/paradedb/paradedb.
