Careers at Relling

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 and own 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, and validate fixes on hardware. What we're looking for: Experience shipping and supporting software on real robotic or hardware systems, with clear ownership you can explain end to end. Strong programming fundamentals in Python or C++ and sound engineering judgment. Comfort debugging across software and hardware interfaces, using measurements and tests to find root causes. ROS/ROS 2, computer vision or robot motion experience is useful; a specific middleware background is not required. 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.

This is a full-time, in-person role in Potrero Hill, San Francisco. What you'll do: Build, test and improve mechanical and electromechanical systems for robotic workcells. Work across mechanical, electrical and software interfaces during cell bring-up. Diagnose failures under load, test fixes and document what works. What we're looking for: Experience building and testing physical systems, with clear ownership you can explain end to end. Strong mechanical and electromechanical fundamentals and sound engineering judgment. A practical approach to debugging: calculations, measurements, root causes 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.

About Relling Systems Hours: 40-60/week. Duration: A minimum commitment of 3–4 months is required. 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 do Build a scoped robotics software feature or diagnostic tool with an engineer. Write tests, inspect sensor data and reproduce runtime failures. Document the interface, test result and remaining limits of your work. What we're looking for Working toward a relevant degree or equivalent practical training. Python or C++ fundamentals and a working project you can show. Interest in software that has to work on real hardware; robotics experience is helpful but not required. How to apply 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.
