About the role
Senior role leading design and development of high-voltage power electronics for satellite propulsion systems. Owns design from architecture through flight qualification, collaborating across mechanical, software, and subsystem teams to deliver reliable, manufacturable space-grade units.
Responsibilities
- Own the architecture and detailed design of a high-voltage power electronics unit, including topology, component selection, and PCB design.
- Design high-voltage DC-DC converters (e.g., phase-shifted full bridge or similar topologies) optimized for efficiency, mass, and reliability.
- Design control electronics for regulation, sequencing, telemetry, and fault protection.
- Perform analysis to validate designs against electrical, thermal, and radiation requirements of the space environment.
- Develop and execute test plans for breadboard, engineering model, and flight hardware.
- Lead schematic capture and collaborate on PCB layout for high-voltage, high-power flight hardware.
- Drive component selection and qualification, including evaluation of radiation-tolerant and high-reliability parts.
- Troubleshoot and debug power electronics hardware throughout development.
- Develop qualification and acceptance test procedures and hardware.
- Support integration of the unit with spacecraft avionics.
- Support Design for Manufacturability (DFM) efforts as the design transitions from prototype to sustained production.
- Define and maintain requirements, interface control documents, and verification artifacts.
Qualifications
- B.S. or M.S. in Electrical Engineering or a related field.
- 5+ years of experience designing power electronics, with demonstrated ownership of designs from concept through hardware bring-up and test.
- Strong fundamentals in switched-mode power conversion, including isolated DC-DC converter topologies and closed-loop control.
- Experience designing high-voltage and/or high-power electronics.
- Proficiency with schematic capture and PCB design tools.
- Strong problem-solving ability and attention to detail.
- Ability to work collaboratively within multidisciplinary engineering teams.
- Ability to work onsite in Burlingame, CA.
