Relling Systems (YC S25) builds ready-to-deploy AI robot workcells for US manufacturers. We design and test in San Francisco and put systems to work on factory floors. This role is in person in Potrero Hill, San Francisco.
What you'll doBuild software that connects perception, planning and control on real robot hardware.
Write tests, diagnostic tools and logs that make intermittent failures easier to reproduce.
Work through sensor and runtime issues with the engineers bringing up each cell.
Strong programming fundamentals in Python or C++, with a project you can explain end to end.
Comfort debugging across software and hardware interfaces.
ROS/ROS 2, computer vision or robot motion projects are useful; a specific middleware background is not required.
Apply with your resume and a short description of something you built. Project links are optional. Tell us what you owned, what failed and how you tested the fix. Coursework, student teams and personal projects count.

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.
