Software Engineer, Test Infrastructure

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.

SOFTWARE ENGINEER, TEST INFRASTRUCTURE (C/C++)

As a Software Engineer on the test infrastructure team, you will design, develop, and maintain SpaceX’s in-house testing ecosystem that powers software and hardware test and validation across all flight systems. You will build and evolve the core test infrastructure framework and supporting applications used for production testing, integration testing, and high-fidelity simulations. The team is focused on building out SpaceXAI, improving SpaceX’s engineering capacity and capability through AI tooling.

This is a high-impact role where you will work across engineering groups to create reliable, scalable, and performant testing tools that accelerate vehicle production and flight software. Our testing software is critical to mission success for all vehicle programs at SpaceX. SpaceX is looking for smart, motivated software engineers who enjoy taking on complex challenges, work well in dynamic environments, and care about software best practices.

Help us build world-class software that is critical to SpaceX’s mission to Mars.
