Radiation Effects Engineer Intern - Summer 2026

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 enrolled currently pursuing bachelor's degrees from four-year universities. 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.

Role

• Help to evaluate fault tolerant electrical systems for operating in a radiation environment

• Assist in creating test plans and documenting test activities and results. Practice efficient issue diagnosis and drafting clear documentation for review by the team.

• Support radiation testing campaigns to up-screen components for TID and SEE.

• Work with the structures team to determine the proper shielding levels across the spacecraft

• Work in a cross-discipline manner across teams to inform their decisions with regards to radiation considerations

• Support test development and early-stage activities, which may include assisting with breadboarding, initial testing, and basic cable harness fabrication as needed.
