Security Software Engineer; Starlink

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

At SpaceX we’re leveraging our experience in building rockets and spacecraft to deploy Starlink, the world’s most advanced broadband internet system. Starlink is the world’s largest satellite constellation and serves millions of users worldwide. We design, build, and operate all parts of the system – thousands of satellites and all of the space-ground infrastructure necessary for a constellation of that size.

As we scale the constellation to hundreds of thousands of satellites, and become a foundation of global connectivity both on earth (and in space), we are looking for excellent engineers to help us build secure, defensible systems from the ground up.
