Thermal Associate Engineer; Fall

Thermal Engineer Associate (Fall 2026)

Associate Engineer positions typically last for twelve weeks, and are salaried roles designed for students who have already received a bachelor's degree (or who will have done so before working at Astranis).

As an Associate Engineer, you will have an amazing opportunity to work on hard problems — we pride ourselves on giving everyone at Astranis a chance to do meaningful work on complex projects, and our Associate Engineers work on projects that are of equal importance and difficulty to the projects we give our full-time employees. Many past Associate Engineers have designed and tested hardware/software that is heading to space on our first satellite, and many now work at Astranis full-time.

If you are still a college student, please apply to join us as an Intern.
