Software Engineer, Developer Productivity

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 making life multiplanetary and expanding consciousness to the stars.

SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.

You will be a core contributor on the Developer Productivity team, designing and building the systems, tools, and workflows that make every SpaceXSI developer incredibly productive. Your mission is to create a world-class developer experience inside SpaceXSI: fast builds, intuitive tooling, reliable environments, and seamless CI/CD. You'll architect, implement, and operate the foundations that power our engineering organization, from local development to global deployments. You'll set technical direction within the team, write and review code, and collaborate across engineering to make it effortless for developers to build, test, and ship quickly.
