  • Strong systems-level thinking across electrical, mechanical, thermal, and power domains

Nice to have

  • Flight heritage — solar array hardware you designed that has successfully operated in space
  • Direct experience with IMM space solar cells and coverglass selection
  • Experience with array electrical modeling and radiation-degradation methods (e.g., EQFLUX / displacement damage dose)
  • Experience defining or running in-house panel lamination processes
  • Familiarity with grounding, bonding, and ESD/arcing mitigation for high-voltage arrays

What you get

  • Salary range of $173,000 - $193,000
  • Competitive equity grant
  • Comprehensive benefits package including medical, dental, and vision insurance
  • 401k retirement plan
