Power Electronics Engineer (Electric Propulsion) El Segundo, CA

Job Description: As a Power Electronics Engineer, you will work closely with a focused technical team to design and analyze critical electronic systems for our product suite, including Seldon and Dreadnought spacecraft vehicles, Genesis propulsion systems, and more. You will have extreme ownership over your work, move quickly, and operate with high agency. As we grow, there will be opportunities to expand your role with the company. In particular, you will own and build the Power Processing Unit (PPU) for General Galactic’s electric propulsion system for multiple spacecraft platforms. You will own your designs from requirements definition and architecture through prototyping, qualification and flight. You will work closely with other members of the engineering team across propulsion, software, avionics, and other disciplines to create a PPU that integrates well with the propulsion system and the spacecraft. Responsibilities may include:

• Define and own power electronics architecture and converter topologies, including for a kW-class PPU for an electric propulsion system.
• Take circuit designs from concept through completion, including component selection, circuit analysis, schematic capture, and PCB layout.
• Define PPU-to-spacecraft communication and power interface.
• Build, bring up and test hardware on the bench and with electric thrusters, while developing test plans, equipment, and scripts
• Qualify designs through vibration, shock, TVAC, EMI/EMC, and radiation testing.
