Job description

Engineering · US, Boston, MA · FullTime · Senior level

This role centers on hands on work with early humanoid robot builds: assembling, debugging, and fixing electrical problems as designs change quickly. A strong candidate has done rapid physical prototyping and traced faults in custom hardware, understands low voltage and mixed signal circuits, connectors, and sensors, and can write clear test plans and repair guides. Comfort with shifting priorities and working across mechanical, electrical, and software teams matters more than polish.

How it fits the AI era

The robots themselves run on an AI framework, so the engineer builds and repairs the physical systems that AI depends on. Much of the diagnosis still comes from careful hands on testing and judgment about what failed and why. Clear records of failures and fixes feed back into design and help the AI driven platform improve.

How it builds AI experience

Working on humanoid hardware tied to an AI framework gives direct exposure to how AI behavior meets real electrical and mechanical limits. Building skill here means learning to document failures in ways software and AI teams can use, and getting familiar with automated test and diagnostic tools in hardware labs. Experience with mobile or human sized robotics reliability adds weight.

Worth showing

• Rapid physical prototyping


• Electrical fault troubleshooting


• Low voltage mixed signal circuits


• Test plans and runbooks
