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: We're seeking an experienced Structural Engineer specializing in mission-critical facilities to join our infrastructure team supporting the rapid build-out of large-scale compute clusters and data centers. This role will play a key part in designing and delivering resilient, high-performance structural systems for hyperscale AI training facilities. You'll collaborate closely with cross-functional teams—including mechanical, electrical, civil, and construction partners—to ensure structural designs support extreme compute densities, seismic resilience, vibration control, rapid deployment timelines, and operational uptime requirements. This is a full-time, on-site (or hybrid) position with occasional travel to project sites. RESPONSIBILITIES: Lead structural design and analysis for large-scale data center and compute facilities, from conceptual design through construction administration Develop and review structural models, calculations, drawings, and specifications using tools like Tekla Structures, ETABS, RISA, STAAD, or equivalent Oversee multidisciplinary coordination, ensuring seamless integration of structural systems with MEP, cooling infrastructure, raised f
