What you will do

• Own the technical direction and architecture of spacecraft electrical power systems, including solar arrays, batteries, power distribution units, and protection circuitry.
• Lead trade studies, power-system budgets, peak power tracking strategies, fault management, and architecture definition across multiple programs.
• Drive design, analysis, verification, qualification, and system-level integration of power hardware from concept through production, launch, and on-orbit operation.
• Conduct derating, worst-case circuit, FMEA, radiation, and reliability analyses, defining mitigation strategies for space-environment risks.
• Lead EMI/EMC, thermal-vacuum, and vibration qualification campaigns and represent power systems in design reviews with internal stakeholders and customers.
• Set EPS design standards, mentor engineers, and coordinate interfaces with avionics, software, and harness subsystems.

Requirements

• Bachelor’s degree in Electrical Engineering or a related field.
• At least 12 years of professional experience designing electrical power systems, including significant spacecraft or high-reliability EPS experience.
• Deep expertise in solar arrays, Li-ion and LiFePO4 batteries, charge control, DC/DC converters, peak power tracking, and power distribution.
• Experience with spacecraft power modeling, analysis, fault management, system architecture ownership, and hardware delivery.
• Strong knowledge of derating, worst-case circuit analysis, reliability methods, radiation effects, and mitigation techniques.
• Must be a U.S. citizen, lawful permanent resident, protected individual, or eligible to obtain the authorizations required under ITAR.

Nice to have

• Master’s degree in Electrical Engineering or a related field.
• Experience with EMI/EMC testing, lab equipment, and HIL/SIL system integration and debugging.
• Knowledge of power-supply stability analysis, compensation techniques, spacecraft charging mitigation, GEO or other demanding orbital regimes, and EGSE development.
• Experience in a fast-paced startup or similarly dynamic environment.

Culture & Benefits

• Health, dental, vision, and HRA/HSA options.
• Paid time off, paid holidays, and parental leave.
• 401(k) and equity participation.
• Collaborative environment focused on ambitious space-security technology and cross-disciplinary engineering.
