Manager, Supercomputer Site Reliability Engineering - 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 the Critical Facilities Operations Manager at SpaceXSI Memphis, you will own the reliability, performance, and continuous improvement of critical data center infrastructure, including power, cooling, and environmental systems. You will lead and develop a team of Facilities Operations Supervisors and Technicians, driving hands-on technical excellence, strategic operational planning, process optimization, vendor management, and cross-functional collaboration. This role emphasizes building a high-performance, team-first culture while ensuring maximum uptime, safety, and efficiency across the site. RESPONSIBILITIES: Lead, mentor, and develop a team of Facilities Operations Supervisors and Technicians, fostering a culture of excellence, accountability, collaboration, and continuous improvement.

ABOUT THE ROLE: As a Site Reliability Engineer focused on Hardware, you will serve as an expert focused on firmware, hardware specifications, vendor relations, and failure analysis. You will proactively identify and resolve hardware issues, manage RMA processes, and stay ahead of emerging hardware technologies to support SpaceXSI's data center operations. This role demands deep technical expertise in hardware diagnostics, and forward-looking hardware evaluation. RESPONSIBILITIES: Analyze firmware packages and hardware specifications for upcoming releases for compatibility, performance, and reliability in SpaceXSI's data center environment. Run security scanning and CVE / vulnerability analysis on firmware and related components. Flag safety issues (electrical, thermal, power-protection, fail-safe behavior) before the package hits the floor. Investigate and diagnose hardware failures, including "grey failures" (ambiguous or intermittent issues), proving them as true hardware defects through rigorous testing and data analysis. Manage vendor relationships, including initiating RMA (Return Merchandise Authorization) claims, negotiating beyond standard processes when necessary, and h

ABOUT THE ROLE: The Data Center Engineering team builds the internal systems and platforms that keep our data centers running at the scale and reliability required for frontier AI training and inference. We partner closely with datacenter operations, research, and infrastructure teams to deliver high-leverage tools that turn raw operational data into clear insight and action. RESPONSIBILITIES: Build and operate the software stacks that make site operations scalable, auditable, and fast — including repair trackers, vendor turnback workflows, operational dashboards, and their integrations. Your users are the technicians, managers, NOC operators, and leadership who run the fleet. Design, build, and operate multi-service production systems (UI, APIs, data pipelines, auth, and on-call) for systems such as SRT-style repair/maintenance trackers and vendor turnover/turnback state machines. Own correctness of operational state: node state accuracy, queue ownership, and audit trails — the data that decides what work happens on the floor. Build and maintain integrations with ticketing, inventory/rack systems, telemetry stores, and vendor portals. Keep the tools themselves reliable: uptime,

ABOUT THE ROLE You will oversee mechanical contractors and crews building the advanced mechanical infrastructure for SpaceXSI's Memphis Data Center — including large-scale HVAC and cooling systems, chilled water plants, condenser water systems, process piping, pumps, CRAC/CRAH units, cooling towers, and fire protection systems. If you thrive on hands-on leadership, complex industrial mechanical construction, and contributing to high-impact AI infrastructure, join us to help deliver one of the most advanced and efficient data centers in the world. This is a full-time, onsite role based in Memphis, Tennessee, with relocation required depending on additional construction locations within the US. RESPONSIBILITIES Oversee and coordinate mechanical installations during night shift hours, including chilled water piping, condenser systems, HVAC equipment, cooling towers, pumps, heat exchangers, ductwork, CRAC/CRAH units, and fire suppression systems for SpaceXSI Data Centers. Manage and schedule mechanical contractors, subcontractors, and on-site crews to deliver project milestones on time and to SpaceXSI's exacting quality and reliability standards.

ABOUT THE ROLE: As a Supervisor on the power generation team, you will lead the technicians who operate, maintain, and repair on-site generation that powers SpaceXSI's high-density AI supercomputing facilities. You will oversee plant technicians, process technicians, and electrical technicians as one operations and maintenance team — covering gas turbine packages, balance-of-plant, process/fluid systems, and plant electrical systems through 34.5 kV. You will operate with autonomy to solve diverse and complex problems, manage multiple workstreams at once, and work in a dynamic, fast-paced plant environment. This role directly impacts reliability, safety, and uptime at the Southaven and Memphis sites. You will keep generation online, keep maintenance disciplined and cost-effective, and build a technician team that can respond to trips, outages, and commissioning without losing the day-to-day plant. RESPONSIBILITIES: Lead a team of plant technicians, process technicians, and electrical technicians responsible for inspections, testing, operations, maintenance, and repair of power generation systems, including gas turbines and generators, balance-of-plant, fuel gas and process/fluid
