The role
You will turn designs and test plans into working hardware. You will partner with systems, mechanical, electrical, and firmware engineers to build, wire, bring up, and test robots and subsystems.
What you will do
- Assemble, wire, and bring up robotic systems and subsystems following engineering drawings and work instructions
- Execute test plans and procedures and collect, log, and organize test data
- Build, maintain, and improve test fixtures and jigs
- Run standard test equipment to triage and debug issues
- Support cross disciplinary triage and escalate findings to engineers
- Aid early robot deployments by going on site and potentially being on-call
- Document build logs, write standard operating procedures, and surface recommendations
- Perform soldering, crimping, rework, and light fabrication
- Maintain lab equipment, tools, inventory, and consumables
- Use basic scripting (Python) to run test routines or parse data
Required qualifications
- 2+ years of hands on experience building and testing robots or complex electromechanical systems
- Ability to read and work from schematics, mechanical drawings, BOMs, and work instructions
- Comfort with soldering, crimping, hand tools, and basic mechanical/electrical fabrication and assembly
- Familiarity with standard diagnostic tools (oscilloscope, multimeter, logic analyzer)
- Strong, detail-oriented record keeping and a habit of clear documentation
- Comfort working in a fast-moving prototype environment
Nice to have
- Exposure to protocols including CAN, Ethernet, USB, MIPI
- Hands on experience with actuators, cameras, microcontrollers
- Soldering and rework to IPC standards
- Comfortable with agentic coding tools (Claude Code, Codex, etc.)
- Prior experience in a robotics startup
