  • Propulsion system architecture
  • Fluid systems
  • Combustion and thermal analysis
  • Pressurized systems
  • Test infrastructure and operations
  • Integration and qualification testing
  • Feed systems, valves, regulators, and tanks
  • Engine controls and embedded systems
  • Ground support equipment (GSE)

What We're Looking For

We seek engineers with experience in:

  • Rocket propulsion
  • Satellite propulsion
  • Fluid systems engineering
  • Cryogenic systems
  • Thermal systems
  • Test engineering
  • GNC/controls related to propulsion
  • High-pressure or harsh-environment systems

Preferred Qualifications

  • BS, MS, or PhD in Aerospace Engineering, Mechanical Engineering, or related field
  • Experience designing or supporting propulsion or fluid-based systems
  • Strong analytical and problem-solving skills
  • CAD, analysis, testing, or integration experience relevant to propulsion hardware

Compensation and Benefits

  • Equity in Cowboy Space Corp.
