Full Job Description
Power Avionics Engineer
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
Basic Qualifications:
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
Preferred Qualifications:
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
Compensation and Benefits
The salary range for this position is $120,000 - $175,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity.
