SpaceX // design, manufacture & launch of advanced rockets & spacecraft
Apply To Job

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 & 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 & scale custom-built mission-critical software products for engineering, test, & launch. These products are used to deliver the software flying rockets, spacecraft, satellites, & 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 & maintain.

SpaceX relies on our vehicle software being built quickly & correctly, tested rigorously, & 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 & want to make an impact on a super inspiring mission. We are looking for engineers who treat fellow teammates with fairness, respect, & support. You will have full ownership of challenging problems, working with a team of enthusiastic engineers to design & 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 & your team produce.
