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 push the boundaries of in-space capabilities with products such as our Starlink low Earth orbit satellite constellation, Starship spacecraft, and Falcon 9 launch vehicle. Our missions support scientific research, classified national security operations, and commercial endeavors. Security and reliability are at the core of these programs.

The SpaceX product security team is seeking technical, passionate security engineers to influence the security of software and hardware across our product lines. We are looking for people who see the big picture, prioritize accordingly, and are comfortable with working at different levels of abstraction.

Ideally, you have notable skills in one or more of the following: exploit development or mitigation, security architecture design, firmware security, software development, or operating system security. Being flexible, communicating clearly, and establishing and maintaining productive working relationships with other engineering teams are paramount to success.

If you are passionate about hunting for vulnerabilities, love the challenges of defense, and want to make an impact on an inter-planetary scale, then we want to talk to you!
