About this role
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. ABOUT THE ROLE You will be a core contributor on the Developer Productivity team, designing and building the systems, tools, and workflows that make every SpaceXAI developer incredibly productive. Your mission is to create a world-class developer experience inside SpaceXAI: 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. Excellence means SpaceXAI engineers feel like they’re working in the best development environment in the world—one so good that parts of it could eventually become external features of Cursor itself. EXAMPLE PROJECTS INCLUDE - Building a multi-platform development environment that works seamlessly across macOS, Windows, and Linux. - Designing and maintaining CI/CD systems—merge queues, build caching, flaky test quarantine, observability, and safe rollout pipelines. - Automating developer machine provisioning—from laptop setup and reset automation to interview and onboarding workflows. - Partnering with backend and infrastructure teams to ensure local testing and debugging just work, with near-perfect parity between development and CI environments. YOU MAY BE A FIT IF - Have experience working on developer productivity, internal platform, infrastructure, or build/test systems. - Regularly write and review code, and enjoy improving build systems, scripting CI pipelines, and refining developer tooling. - Have built or maintained tooling or infrastructure for large-scale or multi-language codebases. - Care deeply about developer velocity, reliability, and maintainability, and apply sound technical judgment to improve them. - Are energized by tightening feedback loops and making development feel effortless, fast, and enjoyable. We're in-person with cozy offices in North Beach, San Francisco and Manhattan, New York, replete with well-stocked libraries. APPLYING If there appears to be a fit, we'll reach to schedule 2-3 short technicals. After, we'll schedule an onsite in our office, where you'll work on a small project, discuss ideas, and meet the team. #LI-DNI
