Full Job Description
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
$120,000 - $190,000 a year
Exempt, full-time, on-site in Watertown, MA. Final pay within the range is based on experience and skills.
