Position: Aerospace Thermal Engineer — Space Infrastructure | Austin, TX (On-site)

Aerospace Structures & Thermal Engineer - Space Infrastructure | Austin, TX (On-site)

Client is a 12-person space infrastructure company building autonomous bio-factories in orbit - producing advanced materials and enabling drug discovery impossible on Earth. Two satellites launched, NASA Tech Leap Prize winner, 8 more missions planned over the next two years. $30M funded, Series A incoming.

You'll own structural and thermal design end-to-end on their next generation of spacecraft. The critical question is yours to answer: will this vehicle survive?

What you'll do
  • Design primary structures, load paths, internal supports, and hard points; lead mass reduction efforts
  • Perform FEA, thermal modeling, and margin calculations using ANSYS to validate flight hardware
  • Select and evaluate materials - composites, ablatives, thermal barrier systems - for extreme environments
  • Develop and execute qualification test plans covering structural, thermal, vibration, and environmental testing
  • Collaborate closely with GNC, systems engineering, and manufacturing teams through to flight
Stack:

ANSYS, Nastran, Abaqus, Python, MATLAB, CAD

Strong fit if you have:
  • 3-8 years aerospace structures and/or thermal engineering with hands-on flight hardware experience
  • Personally designed hardware that flew - spacecraft, launch vehicle, reentry system, missile, or hypersonics; must be able to describe specific subsystem ownership in technical detail
  • Experience in high-temperature environments where thermal management was a primary design constraint
  • Background in composite structures, ablative materials, or thermal protection systems
  • BS or higher in Aerospace Engineering, Mechanical Engineering, or Physics
Details:
  • Full-time, 5 days on-site in Austin TX
  • $150K-$180K depending on experience + competitive equity
  • Must be a U.S. Person (citizen or permanent resident); no visa sponsorship
Not a fit:
  • Cannot describe specific hardware they personally designed - peripheral contributors to large programs are not a fit
  • Pure analysts with no hardware design or build experience
  • Legacy aerospace prime backgrounds with low ownership, slow-cadence program experience
