Key tools and skills
- Thermal Desktop / SINDA — Industry-standard spacecraft thermal modeling
- ANSYS / COMSOL — FEA thermal analysis
- MATLAB / Python — Custom thermal models, orbital heating analysis
- Testing — Thermal vacuum (TVAC) chamber test design and execution
- Materials — MLI, thermal coatings, phase-change materials, heat pipes
Thermal engineering is niche enough that experienced practitioners are in high demand. An engineer with 5+ years of TVAC testing and Thermal Desktop experience can command premium salaries.
