Lumen Labs | Robotics / Hardware Engineer | San Francisco, CA | ONSITE | Full-time | $130k–200k + equity | https://lumenresearch.co

I'm Daniel, co-founder. Lumen Labs is building the cognitive layer for physical AI. Nearly every major robotics effort today teaches machines by showing them thousands of hours of human teleoperation. We think that paradigm has a ceiling, and we're working on nature-inspired architectures for unstructured environments (construction sites, mining, pipelines, battlefield). Pre-seed, backed by top VC funds and operators from robotics/AI companies.

We're a team of two and hiring teammate #3 to own the hardware and infrastructure that keeps our research platforms running: the ROS2 (Humble) stack across onboard and offboard compute, sensor integration and calibration (LiDAR, depth, IMU, encoders), the safety pipeline during autonomous runs, and getting trained policies onto real hardware. Today that's wheeled navigation; we're dipping our toes into drones and eyeing weirder platforms like pipeline inspection. Where we're at: zero-shot sim2real transfer with a policy that runs at 100Hz on an ESP32 and took under a day to train.

You: hands-on with real mobile robots (UART, encoders, PWM, IMU, LiDAR), strong Python + embedded, comfortable reading code you didn't write, and can debug hardware and firmware at the same time. If "full-stack" to you means firmware, a multimeter, and a ROS node in the same afternoon, you'll fit right in. Visa/relocation support for the right person.

Full posting: https://desert-bearskin-26d.notion.site/Robotics-Engineer-Ro...

Email hi@lumenresearch.co, mention HN, and tell us about a project you've built. If you can link to a time you got a trained policy running on real hardware, you go to the top of the pile.

Ours Privacy | Senior Platform Engineer | Remote (US) | Full-time | https://oursprivacy.com/careers

We're building the marketing infrastructure healthcare has been missing — a privacy-first CDP and consent management platform in one product, so healthcare marketers can run real campaigns without putting patient data where it doesn't belong.

You'd own our AWS platform end to end: Lambda, Kinesis, SQS, Fargate, DynamoDB. High-volume event pipelines feeding dozens of third-party destinations, where correctness actually matters. The work is infrastructure-as-code, pipeline reliability (retries, idempotency, DLQs, backpressure), CI/CD and developer experience, and the observability and controls behind our HIPAA and SOC 2 posture.

Small team, large surface area, real latitude to fix what you find. TypeScript/Node throughout. 5–8 years experience, deep AWS, and you've debugged a streaming system under load.

Email careers@oursprivacy.com, subject "Senior Platform Engineer." I read every one.

Obi9 | Full-Stack Engineer | REMOTE (US time zones) | Contract or Full-time | https://obi9.ai/jobs/full-stack-engineer

A hedge fund analyst covering therapeutics has to watch hundreds of companies at once: press releases, SEC filings, management calls, updates on government sites, clinical data publications. Obi9 ingests all of it and surface what matters. Hedge funds pay for it today.

We are early and the team is small, so you would own entire surfaces of the product rather than pick up tickets:

- Ship full-stack features end to end, from the data model to the interface.

- Build the ingestion and enrichment pipelines that turn raw data into rich insights and alerts.

- Work on AI-backed features, from ideation to serving them in the webapp and over MCP.

- Make heavy data legible: dense tables, financial charts, document viewers, a live alert stream.

Stack: React + TypeScript, Node, Elixir, Python, distributed AI pipelines.

Beyond full-stack ability we want someone who already understands one of these worlds. One is enough, we are not asking for all four:

- Financial information systems. Bloomberg, FactSet, AlphaSense, Capital IQ, PitchBook. You know what entity resolution, identifier mapping and point-in-time data cost to get right.

- Financial domain knowledge in healthcare. Equity research, valuation, or time spent living inside filings and models.

- Audio and transcription. OtterAI Deepgram, AssemblyAI, Whisper. Diarization, speaker attribution, turning messy call audio into something quotable.

- AI-intensive products where the pipeline IS the product. Legal AI, document intelligence, medical coding. You know what evals, grounding and extraction schemas that hold actually cost.

Minimum: 5+ years building production web applications, a technical degree, fluency with current AI tooling, and eight continuous hours inside the 8:30am to 5:00pm ET window.

AiMi | Full Stack AI Engineer | Remote(Everywhere) | Full-time

AiMi builds agentic AI infrastructure for capital markets: autonomous agents that ingest venue and vendor notifications, assess impact across client infrastructure, and drive change management workflows in real time, replacing what used to be manual, static processes for exchanges and their ops teams. live production platform, not a pilot.

you'd work across the full stack: React/TypeScript frontend, Node.js backend, AWS Lambda. concretely: shipping features in the agent pipeline, building MCP-based connectors and skills that extend what our agents can reach, running evals on agent accuracy and reliability, building observability and alerting for agent latency/error rates/failed workflows, and making long-running LLM, agent, and SSE calls actually resilient (timeouts, retries, circuit breakers, fail-fast, recovery). also a fair amount of diagnosing dependency/version conflicts in a Node.js/npm monorepo, which is its own skill.

looking for 2-3+ years hands-on experience, solid Node.js and REST API background, real hands-on work with LLMs or agent frameworks (Mastra, LangChain, LlamaIndex, Claude, OpenAI or similar), comfortable with AWS (Lambda, Bedrock, DynamoDB, S3, Cognito, API Gateway, CloudWatch), MongoDB/DynamoDB, and genuinely tests what you ship (unit, integration, e2e). familiarity with spec-driven development (Claude Code, Cursor, CodeRabbit or similar) is a real plus since that's how we work day to day. bonus points for capital markets/trading infra background, LLM observability tooling like Langfuse, SSE streaming experience, or PostHog.

you'd be working on great things here: real architectural decisions at an early-stage company, visible impact from week one, and room to grow into a senior or lead role as we grow.

Trax | https://www.traxtech.com/ | Onsite Cebu PH, Remote Costa Rica, Remote US are possible | Full-time | Architect

I work best as a team - with someone who can challenge my assumptions and bolster my weaknesses. I'm looking to increase the bandwidth of the architecture function at Trax, as I can't do it alone!

We BOTH need to be strong in: * Communication - we lead by influence, not by authority. Kindness is required! * Ego-free problem solving - good ideas come from anywhere. * Reliable software designs - things that work on dirty data, incomplete testing, and AI-enabled development workflows. * Building the first prototype in an area with zero guidelines - careful choices and evaluation of vendors, setting an example to follow.

You should be strong in: * Angular, Vue, Javascript, and web serving best practices for development organizations for long term health. * Developer enablement and tooling in the Node.js ecosystem - shared component architectures, design systems, etc. * Data-heavy applications and their operation and security needs.

I am strong on the infrastructure, DevOps, k8s, and backend and data stacks. So don't worry about relative weaknesses there, though you will need some understanding.

This would be a good first architecture position for a Staff or Senior Staff level full-stack technical leader who wants to expand their scope. My email is in my profile!

Duets Network | Founding Engineer | REMOTE (US) | Equity + discretionary cash | ~10–15 hrs/wk

Duets Network is an AI-powered platform connecting startups and investors across the sports and entertainment industries. We are building a dynamic ecosystem that bridges founders, capital, and strategic partners to drive meaningful growth and collaboration at the intersection of technology and culture.

The initial product is built out, and we're now looking for a fractional Founding Engineer to guide the technical side moving forward: architecture, infrastructure, data/recommendation systems, security, and scalability.

Our founding team: CEO, ex-Universal Music Group; CBO, ex-Andreessen Horowitz. You'd work directly with the founders, with no existing engineering org, and would:

- Assess and improve the existing React / Node.js / PostgreSQL / AWS codebase and infrastructure

- Set engineering architecture, standards, and technical priorities

- Design the data + recommendation/scoring layer behind founder/investor/partner matching

- Build out DevOps, CI/CD, monitoring, and deployment processes

- Make pragmatic build-vs-buy decisions and coordinate external engineers/vendors as needed

- Serve as the primary technical team member, with real influence over the technology foundation and future engineering org

We're particularly interested in someone who has owned architecture end-to-end. Ideally with experience in matching, recommendation, ranking, or scoring systems. You should be comfortable explaining technical tradeoffs to non-technical founders and investors.

This is a fractional role (~10–15 hrs/wk), compensated with equity plus discretionary cash. It's a fit if you want the opportunity to be an early technical team member without a traditional full-time commitment. We're early-stage and moving fast, so you don't need to check every box, we're looking for someone curious, adaptable, and excited to build with us.

If interested, email team[at]duetsnetwork[dot]com with "Founding Engineer" in the subject line.

River (AI voice agents for B2B sales) | New York, NY | ONSITE | Full-time

We build AI voice agents that run live B2B sales calls — real-time voice, browser-driven product demos, automated follow-up. We're pre-seed, backed by the founders of Ramp, Kalshi, and JumpCloud, revenue is on, and demand is already outpacing what we can serve. It's a genuinely fun problem, and we'd love to find the right people to build it with.

We're hiring two founding engineers. To save everyone's time, here's what the role really needs — if a few of these are a strong yes, we'd love to hear from you:

NYC-based and up for working in person (5 days). We're not able to do relocation or visa sponsorship right now. TypeScript/Node as your main production stack — the one you actually ship in day to day. You've shipped real software that real people used — something in production, with revenue, or a startup you built (not tutorials or coursework). You've built something real with LLM APIs. You like owning things end to end — finding the problem and fixing it without waiting for a spec.

Two levels:

Founding Backend Engineer (5+ yrs): real-time/streaming depth (WebRTC, voice, low-latency), plus infra and reliability ownership. Founding Product Engineer (2–4 yrs): frontend-leaning (React/Next.js), customer-facing, CS degree or equivalent standout shipped work.

No need for a formal resume — just send a link to something you're proud of that real people used, and a line on what you owned. We read every one.
