Radiation Effects Engineer — Associate Program 2024 (Fall 2024)



San Francisco, CA, USA
Posted on Friday, June 21, 2024

Astranis is on a mission to bridge the digital divide by connecting the four billion people worldwide who currently lack internet access. We're doing this by building the next generation of smaller, more cost-effective spacecraft to bring the world online.

As a team, we’ve launched two satellites into orbit, signed ten commercial deals worth over $1 billion in revenue, raised over $500 million from top global investors, and recruited a team of over 300 world-class engineers. We all work out of our (legendary) San Francisco office, which was once used to build ships during the World Wars.

Our satellites, which operate from geostationary orbit (GEO), weigh only 400 kg and utilize a proprietary software-defined radio payload. Each satellite can connect over two million people, and we’re very excited for the impact we’ll soon have in the Philippines, Peru, Mexico, and more!

Backed by substantial funding and a passionate, collaborative team, we offer a rewarding work environment where you'll learn and make a significant impact, no matter where you are in your career.

Apply and join us on our journey towards global connectivity!

Radiation Effects Engineer — Associate Program
As our Radiation Effects Associate 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.
Associate programs at Astranis typically last for twelve weeks, and are salaried roles designed for students enrolled in graduate programs, or graduates of four-year universities.
As an Associate, 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 Associates 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.
