About The Position

Tacit is an early-stage deep tech startup based in San Francisco developing hardware that rethinks human-computer interaction. The company is backed by General Catalyst, Khosla Ventures, and Greylock Partners, and has a founding team from Stanford, BrainGate, Oculus, and Tesla.

The System Electrical Engineer Intern will help validate, debug, and improve electrical blocks in Tacit's sensing hardware, working alongside hardware engineers with prototype boards. The role includes bench bring-up and measurements, investigating hardware issues, and translating findings into design updates. The intern will contribute to the product journey from prototype to mass production, including bring-up, design updates, and testing. Interns are hired on a rolling basis, with flexibility on start date and timeline.
