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.


Enabled by a constellation of low Earth orbit satellites, Starlink will provide fast, reliable internet to populations with little or no connectivity, including those in rural communities and places where existing services are too expensive or unreliable. Starlink is now delivering initial beta service and accepting pre-orders both domestically and internationally, and will continue expansion to near global coverage of the populated world in 2021.

SpaceX is seeking technical, passionate engineers to secure Starlink’s consumer applications environment. We are looking for people who see the big picture, prioritize accordingly, and are comfortable with working at different levels of abstraction.

Ideally, you will have notable skills in one or more of the following: web application security, software engineering, mobile app security, or network security. Being flexible, communicating clearly, and establishing and maintaining productive working relationships with other engineering teams are paramount to success.

If you love using your technical skills to solve challenging problems and want to make a great impact, then join SpaceX to be among the first to secure some of the world’s most innovative technologies.
