# Software Engineer, Client 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 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. SOFTWARE ENGINEER, CLIENT INFRASTRUCTURE As an Engineer on the Client Infrastructure team at SpaceXSI, you'll design and build the systems that make our desktop experience performant and stable for millions of developers. You'll work across the core architecture of the Cursor client, from build and distribution systems to performance instrumentation and shared abstractions that other teams rely
