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.

Strong electrical and controls fundamentals and sound engineering judgment. A practical approach to debugging: measurements, root causes, tests and validation.
