Lead Electrical Reliability Engineer, Data Center 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. ABOUT THE ROLE: As the Facilities Operations Supervisor at SpaceXSI Memphis, you will oversee the maintenance and performance of critical data center infrastructure, including power, cooling, and environmental systems. You will lead a team of Facilities Operations Technicians, driving hands-on technical operations, team leadership, process optimization, and cross-functional collaboration to ensure the reliability and efficiency of our data center. This role emphasizes fostering a team-first culture, prioritizing team focus, and promoting a collaborative work environment. RESPONSIBILITIES: Lead and mentor a team of Facilities Operations Technicians, fostering a culture of excellence, collaboration, and continuous improvement. Oversee maintenance, monitoring, and troubleshooting of data center infrastructure, including HVAC, power distribution, and backup systems. Develop, implement, and optimize preventive maintenance schedules, equipment calibration, and system performance monitoring. Create and enforce standard operating procedures (SOPs) to ensure operational consistency and efficiency. Ensure compliance with safety regulations and industry standards. Collaborate with engineer

ABOUT THE ROLE: We are looking for a Manager of Engineering to own the design, build-out, commissioning, and continuous improvement of automation, controls, and electrical systems at SpaceXSI's power generation facility in Southaven. This plant is critical infrastructure for SpaceXSI's AI supercomputers: it must deliver high-reliability power and supporting utilities at scale, with the uptime and response expected of a mission-critical compute campus. If it has a gas or steam turbine control system, a switchgear lineup, a plant electrical distribution network, a SCADA/DCS point, a control loop, or a supporting utility/process system (water, wastewater, fuel gas, HVAC, cooling) that must run reliably, this team designs it, specifies it, commissions it, and keeps it running. As a Manager, you will lead a team of engineers in a high-reliability, fast-paced environment. This is a hands-on technical leadership role — you will review P&IDs, challenge control philosophies, dive into DCS/PLC architecture, electrical protection schemes, and commissioning details, not just manage a roadmap. You will scale both the team and the systems as generation capacity and AI compute load g
