Intern - Radiation Effects Engineer

As our Radiation Effects Intern you will be supporting the modeling and analysis of the space radiation environment as they relate to our missions as well as physical radiation testing of actual spacecraft hardware. You will have direct impact on our space vehicles by simulating radiation effects at a circuit level, modeling the spacecraft to inform mechanical designs, and performing radiation testing at various laboratories across the U.S.

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.
