Avionics Engineer (Power Electronics)

The Mission Starpath is building the technology to enable human expansion into the Solar System. We are developing systems that will produce the water, power, and oxygen needed for humans to live and work on the Moon and Mars. Our ultimate goal is to build and operate a self-sustaining city on Mars. The Mission Starpath is building the technology to enable human expansion into the Solar System. We are developing systems that will produce the water, power, and oxygen needed for humans to live and work on the Moon and Mars. Our ultimate goal is to build and operate a self-sustaining city on Mars. Starlight is our space solar product. Our goal is to build the lowest-cost, highest-performance space solar power system—one capable of powering most new satellites around Earth and all Starpath equipment on the Moon and Mars. Position Details Location: Carson, CA Employment Type: Full-time Department: Starlight Travel: Occasional Power Electronics Avionics Engineer We are looking for a Power Electronics Avionics Engineer to own the design of Starlight’s power electronics.
