Site Reliability Engineer (Application Software)

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. SITE RELIABILITY ENGINEER (APPLICATION SOFTWARE) The application software team is the central nervous system of SpaceX. We build mission-critical platforms that accelerate vehicle software delivery, testing, and operations for every Falcon 9, Starship, and Dragon mission all while powering Starlink’s global growth. This position will have a meaningful impact on Starship by significantly reducing safety-critical build and test times for vehicle software. We are looking for a Site Reliability Engineer who brings a strong SRE mindset, cares deeply about safety, quality, and attention to detail, and possesses the ability to understand the big picture before writing code. The ideal candidate fully understands what they are building, enjoys hard problem solving, thinks strategically, and is decisive, organized, and self-critical. SpaceX relies on our vehicle software being built quickly and correctly, tested rigorously, and rapidly iterated on. You will build and maintain the tools that make this possible. Every time a Falcon 9 or Starship 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 design, improve, and scale. Aerospace experience is not required. We value smart, motivated, collaborative engineers who treat teammates with fairness, respect, and support, and who want to take full ownership of challenging problems to help make humanity multi-planetary.
