Senior RF Design Engineer

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!Senior RF Design EngineerAs an RF Engineer you will be responsible for design, qualification, and procurement of active RF electronics (frequency converters, SSPAs, LNAs, PLLs, etc) in the RF front end of satellite payloads.
