About the role
About Embedder
Embedder is building AI agents for hardware teams. Our agents read datasheets, generate production C/C++ firmware, and verify their own code in a closed loop on real silicon. We are a YC S25 company backed by CRV, Box Group, and Emerson Collective, with $XM+ raised, 5,000+ engineers using the product, and 100+ paying customers across automotive, aerospace, medical, IoT, and consumer electronics. We sell software and we run a full-stack firmware design service — this role does both.
The Role
You will design and build our core AI application — the planner, verifier, debugger, and model orchestration layer that turns datasheets, schematics, and live hardware signals into working firmware. You'll work directly with hardware companies (ranging from startups to F500s), and dogfood the product on real customer projects.
What You'll Do
- Shape what the next generation of embedded systems tooling will look like and how firmware is written.
- Work alongside our firmware and product engineers to build the industry standard framework for how AI interacts with hardware, debugging servers, test equipment and test benches.
- Build and own evaluation infrastructure for agentic systems.
- Design user interfaces to simply complex hardware and OS traces and visualize test equipment data.
- Use the product on real customer engagements and feed everything back into the system.
- Help define engineering culture, hiring bar, and technical roadmap as one of our first engineers.
Who You Are
- Evidence of building complex systems from scratch, regardless of years in industry.
- You've built non-trivial AI agent systems — multi-step tool-using agents, coding agents, or eval harnesses. Bonus if any is open source or in production.
