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 Electrical Engineer — Power: High Voltage

As a Senior Electrical Engineer for High Voltage Power, you will be tasked with conceptualizing, designing, testing, validating, and otherwise owning power converters and power systems specializing in high voltage. You will work with a range of multidisciplinary team members to engineer the best solution, trading size, weight, cost, power efficiency, thermal management, and other key requirements. Specific high voltage considerations include electric field analysis, familiarity with partial breakdown mechanisms and prevention in solid, gas and vacuum insulation systems, partial discharge testing, industry standards for creepage and clearance and potting processes for high voltage systems.

You will be joining an established team of experienced power engineers working to create the next generation of power conversion on our next generation satellites. Day-to-day will include simulations, schematic, layout, and hands-on board bring-up, debugging, and optimizing. Every day is a new exciting challenge to build what hasn't been built, and a new exciting opportunity to put your skills to the test engineering the future of the space industry.
