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.
As the Director of Site Operations, you’ll own node and rack uptime for SpaceXSI's AI supercompute cluster—the most advanced of its kind. This role is the extreme owner of cluster health and customer Service Level Agreements across 5+ sites operating 24/7. You’ll lead a 250+ person organization of site managers, shift supervisors, and technicians, plus the site reliability engineering team that monitors cluster health and drives fault mitigation at scale. We’re looking for a hands-on operations leader who can build a culture of excellence and accountability, partner tightly across the company, and keep uptime exceptional as we grow.
