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.


SpaceX is hiring a Principal Software Engineer to join our Security Engineering team which owns the custom security software, tools, and systems that protect against threats to our rockets (Falcon and Starship) and the network and technology utilized by our astronauts and employees.

You should expect to spend 80% of your time programming, automating, and writing novel security solutions to defend against the constantly changing threat landscape. We are looking for people with a track record of shipping reliable software and who have a broad understanding of security design and best practices.

In-depth security experience is not required to be successful in this role - we look for smart, motivated, collaborative software engineers who are excited about solving challenging security problems.
