Power Systems Engineer

Responsibilities

• Own power subsystems end-to-end—from requirements definition and architecture through design, manufacturing, integration, and in-flight operations
• Design DC/DC converters, power distribution units (PDUs), battery management systems (BMS), and solar array interfaces for high-reliability space applications
• Model and simulate power system performance under nominal and fault conditions using tools such as LTspice, PLECS, or MATLAB/Simulink
• Conduct PCB-level design and layout for power electronics with thermal, radiation, and EMI/EMC constraints in mind
• Drive root-cause analysis and troubleshooting of power-related issues in spacecraft and ground systems
• Develop test plans and automate validation for high-voltage and high-current systems
• Work with systems, mechanical, software, and GNC teams to ensure power architecture supports mission-level goals and spacecraft performance
• Contribute to avionics team best practices, including documentation, design reviews, and hardware bring-up processes

Basic Qualifications

• Bachelor’s degree in Electrical Engineering or a related field
• Experience designing and testing power electronics (DC/DC, power conversion, energy storage, etc.)
• Familiarity with power systems modeling and simulation tools
• Proficiency with test equipment such as oscilloscopes, electronic loads, power analyzers, and logic analyzers
• Experience with electrical CAD tools (Altium, KiCad, OrCAD, etc.)
• Strong organizational and time-management skills in a fast-paced environment
• Willingness to work extended hours when required to support critical milestones
• Ability to work onsite in Seal Beach, CA
