Manager, Fiber - Memphis

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: As a Fiber Supervisor at SpaceXSI's Memphis data center, you’ll lead the fiber optic installation and maintenance teams that keep critical network infrastructure online. Working onsite with project management and superintendents, you’ll plan work, direct technicians, and own quality, safety, and schedule on datacenter fiber projects. Expect to stay hands-on, coach the crew, and make sure systems run reliably in support of SpaceXSI's mission of accelerating human scientific discovery through AI. RESPONSIBILITIES: Supervise fiber technicians through all phases of datacenter installation projects, in coordination with the Project Manager and Superintendent Assign daily work, set priorities, and track progress so installations, splices, and repairs finish on schedule and to standard Ensure a safe and productive work environment, including job-site briefings, PPE compliance, and elevation and confined-space practices Develop inspection points and sensor checks so faulty fiber does not degrade system performance Direct troubleshooting, repair, replacement, and installation of fiber optic systems, and verify work before closeout Review and approve replacement of faulty
