Senior Systems Integration & Test Engineer
Tau, Redwood City, CA +1
About the job
About Tau
Power conversion is the bottleneck between the compute, energy, and mobility industries and the future they're trying to build. Most of the industry is still solving it with decades-old approaches. Tau is fixing that. We're a venture-backed hardtech company in Redwood City, building power conversion technology for data centers, EVs, and energy systems. Several products are already moving into production.
We hire people who own problems end-to-end: power electronics, embedded software, controls, test and validation, mechanical design. We solve from first principles, not legacy playbooks. We're past "promising technology." Customers are buying, volume is coming, and the people who join now set the standard everyone builds on after.
About the role
Tau is validating power electronics at the boundary between hardware, controls, software, thermal systems, and the vehicle. Failures rarely belong neatly to one discipline. The job is to design tests that expose those interactions, distinguish product problems from test problems, and turn ambiguous system behavior into defensible engineering conclusions.
This role owns test planning and execution for Tau's power conversion products, including electric motors, onboard chargers, DC-DC converters, and power modules for EV powertrains. You'll define what "validated" means for a given program, plan and run the dynamometer, high-voltage, reliability, thermal, and vibration campaigns that prove it, and drive anomalies to root cause using Tau's existing test capability.
