About the role
- The Power Electronics Engineer role is responsible for the design, development, and integration of electrical systems supporting high power solar arrays and compute payloads.
- You will collaborate with software, mechanical, solar, and propulsion engineers to develop solutions that meet rigorous performance standards for space applications.
Responsibilities
- Own the design, development, and validation of spacecraft power electronics systems from concept through flight
- Architect and implement power distribution systems, including power management, conversion, and regulation for spacecraft subsystems
- Design and analyze DC-DC converters, battery management systems (BMS), and power control electronics for high-reliability environments
- Develop and execute test plans for power systems, including functional, environmental, and hardware-in-the-loop (HIL) testing
- Perform system-level analysis of power budgets, efficiency, thermal performance, and fault conditions
- Implement protection and fault management strategies (overcurrent, overvoltage, short circuit, latch-up protection)
- Partner closely with structures, thermal, software, and payload teams to ensure seamless integration of power systems
- Support board bring-up, integration, and debugging of power electronics in lab and flight environments
- Investigate anomalies and drive root cause analysis to improve system robustness and reliability
- Support vehicle integration, pre-flight testing, and on-orbit performance analysis
Requirements
- Bachelor's degree in Electrical Engineering or a related field
- 3+ years of experience designing or testing power electronics or avionics systems
- Strong understanding of power electronics fundamentals (DC-DC conversion, control systems, power distribution)
- Experience with schematic capture, PCB design, and board bring-up
- Familiarity with lab equipment (oscilloscopes, power supplies, electronic loads) and debugging techniques
- Experience working in high-reliability or hardware-focused environments
Nice to have
- Experience designing power systems for spacecraft, aerospace, or other harsh environments
- Familiarity with battery systems, solar arrays, and energy storage technologies
- Experience with radiation-tolerant design and component selection
- Knowledge of thermal management and its interaction with power electronics
- Experience with hardware-in-the-loop (HIL) testing and system integration
- Familiarity with FPGA or embedded systems as they relate to power control and monitoring
- Experience with reliability analysis (FMEA/FMECA, derating, fault tolerance)
- Ability to work in fast-paced, high-ownership environments with aggressive timelines
