Electrical Engineer (Senior/Staff), Power Systems

Responsibilities

• Lead the design and development of spacecraft electrical power systems, including solar arrays, battery systems, power distribution units, and protection circuits
• Own power architecture trades and drive technical decisions balancing performance, mass, thermal, radiation tolerance, cost, and schedule
• Lead preliminary and critical design reviews (PDR/CDR) for power subsystems, ensuring designs meet program and customer requirements
• Develop and maintain spacecraft power budgets, including generation, storage, distribution, and load analyses across all mission phases from launch through end-of-life
• Perform power system modeling and simulation including on-orbit power generation, eclipse cycling, battery state-of-charge, and transient load analysis
• Design and analyze power conversion and regulation circuits, including DC/DC converters, peak power tracking, charge controllers, and fault protection schemes
• Conduct and review derating analysis and worst-case circuit analysis for power electronics in accordance with EEE-INST-002 and applicable standards
• Perform radiation and reliability analyses for power system components, identifying risks and driving design mitigations for the orbital radiation environment
• Define validation approaches and create development and qualification testing campaigns to exercise power system designs to their limits and ensure reliable hardware
• Develop and maintain documentation for power systems, including design specifications, interface control documents, test plans, and operating procedures
• Provide technical guidance and mentorship to junior and mid-level engineers on the Power team, raising the team's design capabilities and technical rigor
• Continuously improve power engineering processes and practices to drive innovation and efficiency

Qualifications

• Bachelor's degree in Electrical Engineering or related field
• Minimum 8 years of professional experience in spacecraft or high-reliability electrical power systems design
• Strong technical background in solar array systems, battery technologies (Li-ion, LiFePO4), charge control, DC/DC converters, peak power tracking, and power distribution
• Demonstrated experience with radiation effects on power system components and radiation-tolerant design practices
• Experience leading preliminary and critical design reviews (PDR/CDR) for power or electrical subsystems
• Proficiency with power system modeling, analysis, and simulation tools
• Advanced experience with circuit design tools (Altium Designer or equivalent ECAD) and analysis tools (SPICE, MATLAB, or similar)
• Excellent communication and interpersonal skills
