Principal Electrical Engineer, Power Systems

Responsibilities

• Own the technical direction and architecture for spacecraft electrical power systems, including solar arrays, batteries, power distribution units, and protection circuitry across multiple programs
• Lead trade studies and architecture definition that balance system performance, technical risk, cost, schedule, and SWaP constraints
• Drive the design, analysis, and verification of power generation, energy storage, and power distribution hardware from concept through on-orbit operation
• Develop and own power system budgets, peak power tracking strategies, and fault management approaches for diverse mission profiles
• Conduct and review derating analysis, worst-case circuit analysis, and FMEA for critical power hardware
• Lead radiation and reliability analyses to characterize system risk and define mitigation strategies for the space environment
• Define validation approach and lead qualification campaigns, including EMI/EMC, thermal vacuum, and vibration testing of power hardware
• Direct system-level integration of EPS hardware and its interfaces with avionics, software, and harness subsystems
• Set and elevate EPS design standards, processes, and best practices across the engineering organization
• Lead preliminary and critical design reviews and represent power systems to internal stakeholders and customers
• Provide technical guidance and mentorship to engineers across the EPS and broader avionics teams
• Support hardware through production, integration, and launch
