• Space is a warfighting domain. Company seeks those with the talent and ambition to build the technology that secures it.
• OUR MISSION
• Company delivers decisive capabilities for space superiority. We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors — enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground.
• OUR VALUES
• Be the offset.   We create asymmetric advantages with creativity and ingenuity.
• What would it take?  We challenge assumptions to deliver ambitious results.
• It’s the people.  Our team is our competitive advantage and we are better together.
• YOUR MISSION  
• As a Staff Power Engineer at Company, you will be a senior technical leader on the Power team, owning the design, analysis, and performance of spacecraft electrical power subsystems across multiple programs. You will drive power architecture decisions - from solar arrays and energy storage through distribution and protection — and serve as the technical authority ensuring our power systems meet the demanding reliability and performance requirements of operational space missions.  
• 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 electrical ground support equipment (EGSE) for power system testing and hardware-in-the-loop (HIL) validation  
• Support environmental testing campaigns including EMI/EMC, thermal vacuum, and vibration testing of power subsystem hardware  
• Collaborate with avionics, systems engineering, software, and propulsion teams to ensure seamless spacecraft integration of power systems  
• 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

• 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  
• Experience with spacecraft power budgeting across all mission phases, including launch, tip-off, eclipse, and end-of-life  
• Advanced experience with circuit design tools (Altium Designer or equivalent ECAD) and analysis tools (SPICE, MATLAB, or similar)  
• Excellent communication and interpersonal skills  
• PREFERRED SKILLS AND EXPERIENCE  
• Master's degree in Electrical Engineering, Aerospace Engineering, or related field  
• Experience with fault management and autonomous protection schemes for spacecraft power systems  
• Experience with EEE parts screening and qualification per EEE-INST-002 or NASA-INST-002  
• Familiarity with EMI/EMC qualification and mitigation per GSFC-STD-7000 (GEVS) and MIL-STD-461  
• Experience designing, analyzing, and testing for spacecraft charging effects  
• Familiarity with lab test equipment including power supplies, oscilloscopes, electronic loads, and solar array simulators  
• Experience developing EGSE or HIL test environments for power subsystem validation  
• Knowledge of power supply stability analysis techniques  
• Experience with GEO, LEO, or other operational orbit regimes and their implications for power system design  
• Experience working in a fast-paced, startup environment or a similarly dynamic setting  
• COMPENSATION   
• Base Salary:  $135,000-$250,000  
• Equity + Benefits  including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave
