Mechanical Commissioning Technician - 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: SpaceXSI is seeking a Turbine Technician to operate, maintain, and troubleshoot gas turbine generator packages at our power generation facility. This is a hands-on role: you will inspect running turbine packages, support start-up and shutdown, respond to trips and alarms, restore equipment, and keep generation online. You will work across the turbine, generator, and package auxiliaries — following OEM procedures, site MOPs, and engineering direction in a fast-paced environment. RESPONSIBILITIES: Operate, inspect, and maintain gas turbine generator packages (including Solar and 6000-class units) and associated auxiliaries: lube oil, hydraulic, fuel gas, inlet air, enclosure ventilation, cooling, fire/gas detection, and generator systems Support turbine start-up, loading, shutdown, cooldown, and turning-gear operations per OEM and site procedures Perform daily inspections of turbines and package systems; identify leaks, vibration, temperature, and alarm issues early and self-report before they affect generation Troubleshoot and repair operational issues on turbine packages during normal operation, start-up, trips, outages, or commissioning Adjust, repair, or replac
