Communications/DSP Engineer — Intern (Fall 2024)

Communications/DSP Engineer — Intern 2024

Internships at Astranis typically last for twelve weeks, and are hourly roles designed for students who are currently enrolled at a four-year university. 

As an Intern, 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 challenging projects, no matter their seniority. Many past interns have designed and tested hardware/software that is heading to space on our first satellite, and many of them are now full-time employees at Astranis. 

If you have already graduated from a four-year university, please apply to be an Associate Engineer.
