Robotics Test & Debug Engineer

The Role Sonny V2, our semi-humanoid robot, moves into production in early 2027 and ramps to 18 robots a day.

We're hiring a Robotics Test & Debug Engineer to make sure every Sonny that leaves our Watertown factory works.

You'll be the production team's first line of defense: when a robot fails, you find the root cause and fix it. You'll also build the test platforms that catch failures early.

What You'll Own - Robot debug: take failing robots and subassemblies to root cause

- First line of defense: resolve floor issues fast and escalate design problems with clear data

- Bench testing: design subassembly fixtures and hardware-in-the-loop rigs

- Factory acceptance testing: build the end-of-line test every Sonny passes before it ships

- Test automation: write Python test sequences, with results logged to ION and Atlas

- Closing the loop: turn recurring failures into new tests and process fixes

Your First Year - Bench tests live for Sonny's critical subassemblies before the 2027 ramp

- An automated FAT that every Sonny passes, with results traced to serial number

- Most floor issues resolved within Production Engineering, without an Engineering escalation

- Recurring failures trending down month over month

What You Bring - BS in Electrical, Mechanical, Computer or Mechatronics Engineering

- Hands-on root-cause debug of robots or electromechanical systems

- You've built test fixtures, bench rigs or HIL systems that others used

- Python for test automation and data analysis

- Strong electrical skills: schematics, scopes, meters, CAN

- Comfortable on the production floor, working alongside technicians

Nice to Have - Experience bringing a new robot or hardware product into production

- Humanoid, mobile robot or robot arm experience

- Embedded firmware or Linux experience

- MES/PLM experience (ION or similar)

- Daily use of AI tools like Claude to build tools and analyze data
