Job summary

General Galactic Technologies Corporation is seeking a Power Electronics Engineer to own the PPU development for electric propulsion across multiple spacecraft platforms. You will guide designs from requirements through qualification, collaborating with propulsion, software, and avionics teams to create a robust PPU interface with the spacecraft.

The role emphasizes hands-on bench work, rapid iteration, and the ability to operate with high agency in a fast-paced startup environment.

Qualifications

• 4+ years hands-on experience in development of power electronics for spacecraft.
• Schematic and PCB layout design tools (Altium, KiCad, etc.).
• Experience designing isolated DC-DC converters through bring-up and test.
• Circuit simulation (LTSpice or similar) of isolated DC-DC converters.
• Programming ability in C++, Python, etc.
• Experience with PPUs for electric thrusters or plasma devices.
• NewSpace approaches to radiation tolerant component selection.

Responsibilities

• Define and own power electronics architecture and converter topologies for a kW-class PPU.
• Develop circuit designs from concept through prototype, including component selection and PCB layout.
• Define PPU-to-spacecraft communication and power interface.
• Build, bring up and test hardware on bench and with electric thrusters; develop test plans and scripts.
• Qualify designs through vibration, shock, TVAC, EMI/EMC, and radiation testing.
