Space

X 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 Space

X is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

The Platform Team builds the foundational tooling and security infrastructure that empowers every team at Space

X to harness AI effectively. This team creates secure, scalable gateways and proxy systems that allow engineers and operators across the company to write code faster, perform advanced data analysis, connect AI to their daily tools and problems, and turn ideas into deployed solutions with confidence. By onboarding new frontier models, expanding compute capacity, optimizing proxy efficiency for logging and control, and building shared prompts, skills, and infrastructure, this team unlocks reliable, high‑impact AI capabilities across the entire organization.

As a Sr. Software Engineer for Space

X's AI platform, you will be a key technical leader and entrepreneurial builder focused on the leanest and most effective applied use of AI  will design and scale platforms that convert engineering know-how into tested software, automation, and reliable data stores at company scale while creating risk‑mitigation tools such as intelligent code review and PR assistants. Current systems are built with Docker containers acting as secure gateways and proxies that integrate with any cloud compute provider and multiple frontier model providers.

Your work will directly accelerate Space

X production and development by enabling every team to move faster with trustworthy AI.
