Proficiency in designing and testing of 1-10 kW power systems
Familiarity with power system packaging, integration, and testing for space environments
Strong problem-solving skills and the ability to collaborate effectively across multidisciplinary teams
Comfortable working in fast-paced environments with evolving priorities

Nice To Haves

Master’s degree in Electrical Engineering or a related field
Experience with fault-tolerant design and FMECA for safety-critical systems
Background working in configuration-controlled or safety-critical aerospace environments
Prior experience with spacecraft electrical power systems (e.g., solar arrays, batteries, power distribution, or power electronics)

Responsibilities

Design, build, and test electrical power subsystems for flight hardware in orbital environments
Define and maintain power system requirements and perform architecture-level design trades
Analyze and validate power system performance against requirements through modeling, simulation, and testing
Perform solar array sizing, including shading, peak, and average power analyses for orbital missions
Assess radiation effects on electronics and develop mitigation strategies
Conduct fault tolerance, redundancy, and reliability analyses for power systems
Work cross-functionally with structures, thermal, avionics, and GNC teams to ensure power system compatibility with vehicle-level performance
Support environmental qualification and acceptance testing, including thermal-vacuum, vibration, and leak/proof pressure testing
Contribute to vehicle layout and packaging decisions, accounting for radiation exposure and thermal environments
Interface with external vendors and suppliers, owning technical coordination, component sourcing, and qualification to ensure delivered hardware meets performance, quality, and schedule requirements
