Sr. Electrical Engineer

The role

You will lead the design and development of high-voltage power electronics for satellite propulsion systems. This role involves owning the design from initial architecture through flight qualification.

What you will do

• Own the architecture and detailed design of a high-voltage power electronics unit.
• Design high-voltage DC-DC converters 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.
• Develop and execute test plans for breadboard, engineering model, and flight hardware.
• Lead schematic capture and collaborate on PCB layout.
• Drive component selection and qualification.
• Troubleshoot and debug power electronics hardware.
• Develop qualification and acceptance test procedures and hardware.
• Support integration of the unit with spacecraft avionics and Design for Manufacturability efforts.

Required qualifications

• B.S. or M.S. in Electrical Engineering or a related field.
• 5+ years of experience designing power electronics.
• 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.

Nice to have

• Experience designing power conditioning or power conversion units for spacecraft or other high-reliability applications.
• Familiarity with radiation effects and radiation-tolerant component selection for space.
• Experience with plasma or other nonlinear high-voltage loads.
• Knowledge of magnetics design for high-frequency power converters.
• Experience with EMI/EMC design and mitigation.
• Familiarity with space hardware standards and qualification processes (e.g., NASA, MIL-STD, ECSS).
• Experience supporting hardware integration, assembly, or environmental testing.
• Familiarity with embedded control or firmware for power electronics.

Before you apply

• For U.S. Roles: applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual.
• For U.K. Roles: requires Baseline Personnel Security Standard (BPSS) checks and eligibility to obtain UK Security Clearance (SC).
• For Canada Roles: must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR.
