• Defineandmaintainpower system requirements and perform architecture-level design trades
• Analyze andvalidatepower 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 tovehiclelayoutandpackagingdecisions, accounting for radiation exposure andthermal environments
• Interface with external vendors and suppliers, owning technical coordination, componentsourcing, and qualification to ensure delivered hardware meets performance, quality, and schedule requirements

About You

You’re a successful candidate if you are a giver, not a taker. You make things happen. You are exceptional at several things, yet willing to take on efforts in areas of weakness.
