From the original posting
SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.
SR. POWER ELECTRONICS ENGINEER, AI SATELLITES (STARMIND)
SpaceX is leveraging its experience deploying and operating the world’s largest satellite constellation to develop Starmind, a new constellation of satellites capturing solar energy in space to power low-cost, high-performance AI compute for Earth. Realizing this vision demands highly reliable, high performance electrical hardware ranging from power electronics, high speed digital systems, mixed signal designs, robust avionics, networking, and custom compute electronics. These systems must operate in the extreme environment of space while delivering the connectivity, control, power distribution, and processing needed for orbital AI inference.
Our Power Electronics team designs and develops the power conversion and control systems at the heart of Starmind satellites and orbital data centers — enabling the reliable, high-efficiency power delivery required for massive on-orbit AI compute. As a senior member of the team, your designs will run the gamut from low voltage to kV range, and powers from 1W to many kW (applications include high-density compute power delivery, battery systems, motors/actuators, ion propulsion, laser optical links, and other vehicle systems critical to orbital AI platforms).
RESPONSIBILITIES:
- Provide engineering expertise in design, analysis, and testing of DC-DC power converters for harsh environments
- Work on electrical power system and sub-system level design trades and develop requirements
- Define and perform electrical power system verification testing and analysis
