Pay by state
Which states pay Aerospace Engineers the most?
State medians come from the same OEWS release as the national figures. The cost-of-living column divides each state median by that state's BEA Regional Price Parity, restating pay in national-average dollars so a high-cost state and a low-cost one can be compared directly.

Much faster than average
BLS projects employment of Aerospace Engineers to change 8.3% over 2025–2035, roughly 2.4× the 3.5% projected for all occupations. That is 5,700 more jobs.
Annual openings
About 3,800 openings are projected each year, 5.5% of the 68,700 jobs that existed in 2025. Most come from workers leaving the occupation, not from growth alone.
Getting in
How to become a Spacecraft Thermal Engineer
Most thermal engineers hold a bachelor's degree in mechanical or aerospace engineering, with strong coursework in heat transfer and thermodynamics, and many earn a master's. Employers look for experience with thermal analysis software and test hardware, often from internships or student satellite projects.
NASA's annual Thermal and Fluids Analysis Workshop offers free short courses and is a common introduction to the field's tools and methods. Work on defense programs usually requires U.S. citizenship and a clearance.

The work
What does a Spacecraft Thermal Engineer do?
In space, one side of a spacecraft can bake in sunlight while the other faces deep cold. Thermal engineers design the systems that manage this: multilayer insulation blankets, radiators, heat pipes, coatings, heaters and, on larger vehicles, pumped fluid loops. They build thermal models in tools such as Thermal Desktop to predict temperatures across every phase of a mission.
They also plan and run thermal vacuum and thermal balance tests, where hardware is cycled through space-like conditions in a chamber, then correlate their models to the results. On launch vehicles and entry capsules, thermal engineers handle aerodynamic heating and heat shields. They support flight operations when temperatures drift outside predictions.
Day-to-day tasks
- Build and run thermal models of spacecraft and instruments
- Design insulation, radiators, heat pipes and heater circuits
- Specify thermal coatings and materials
- Plan and support thermal vacuum and thermal balance tests
- Correlate thermal models to test data
- Analyze heating during launch and atmospheric entry
- Support flight operations when component temperatures change
Typical tasks, researched by NueCareer from the sources below.
Working conditions and hours
Thermal engineers work mainly at a computer building models, with regular time in labs and test facilities supporting thermal vacuum chamber tests that can run around the clock for days or weeks. Schedules are regular outside test campaigns. Employers include NASA centers, satellite builders and launch companies.
