About Relling
Relling (YC S25) builds ready-to-deploy robot workcells for US manufacturers. We design and test in San Francisco and put systems to work on factory floors. This is a full-time, in-person role in Potrero Hill, San Francisco.
What you'll do: Build, test and debug controls for robotic workcells. Work through motor, sensor and hardware-interface issues with the engineers bringing up each cell. Document tests, diagnose failures and validate fixes on real hardware.
What we're looking for: Experience building and commissioning controls or automation systems, with clear ownership you can explain end to end. Strong electrical and controls fundamentals and sound engineering judgment. A practical approach to debugging: measurements, root causes, tests and validation.
How to apply: Apply with your resume and a short description of a system you built or shipped. Project links are optional. Tell us what you owned, what failed and how you tested the fix.

What We Do
Relling builds and deploys turnkey, AI-native robot workcells for American manufacturers, targeting high-mix, contact-rich production tasks that conventional automation struggles to handle. Its systems automate assembly, machine tending, finishing, kitting, welding, and inspection—work that classical automation cannot economically handle. Cells are scoped and qualified off-site, then run on US factory floors in weeks, bringing physical AI into practical manufacturing operations.
