Senior Propulsion Test Engineer

Astranis
San Francisco, CA

As a team, we’ve launched five satellites into orbit, signed ten commercial deals worth over $1 billion in revenue, raised over $750 million from top global investors, and recruited a team of over 400 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.
