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.


The application software team is the central nervous system of SpaceX – we create mission critical applications that are used throughout SpaceX to accelerate launch vehicle production and flight as well as systems that allow Starlink to grow into a worldwide fast, reliable Internet service.

We are looking for an experienced Site Reliability Engineer to operate and scale custom-built mission-critical software products for engineering, test, and launch. These products are used to deliver the software flying rockets, spacecraft, satellites, and more - every time a Falcon 9 launches, a Dragon capsule docks with the ISS, or a Starlink satellite connects a new community, the software responsible for it was created with the tools you'll build and maintain.

SpaceX relies on our vehicle software being built quickly and correctly, tested rigorously, and rapidly iterated on. This allows us to pioneer technologies that were science fiction a decade ago; you'll work to ensure that software delivery at SpaceX keeps pace with other engineering efforts, to enable our goal of making humanity multi-planetary.

Aerospace experience is not required to be successful here - rather we look for smart, motivated, collaborative engineers who love solving problems and want to make an impact on a super inspiring mission. We are looking for engineers who treat fellow teammates with fairness, respect, and support. You will have full ownership of challenging problems, working with a team of enthusiastic engineers to design and produce solutions that enable SpaceX to move towards our goals at a rapid pace. The success of the missions at SpaceX depends on the software that you and your team produce.
