Controls Technician

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 member of the Supercomputer Physical Infrastructure team, you will provide hands-on support for the integration, commissioning, troubleshooting, and maintenance of control systems across our AI training campuses. This role focuses on safe, structured execution of repairs and recoveries that maximize uptime; wiring and building industrial control panels; supporting PLC, HMI, and SCADA systems; and keeping cooling plants, electrical distribution, liquid-cooling loops, and data halls running. You will work closely with Controls Engineers on the same team. This position is based in Memphis, TN, with work across the Memphis / Southaven campus.

RESPONSIBILITIES:

• Support integration and commissioning of vendor and OEM equipment into campus BMS, EPMS, and SCADA systems and plant PLC controls
• Perform safe controls and electrical work within LOTO, arc-flash, interlock, bypass-control, and restart-verification requirements; identify hazards, verify zero energy, validate safety devices after repair, and escalate unsafe conditions or unauthorized changes
• Maximize uptime of cooling, electrical, and facility control assets through hands-on troubleshooting, basic repairs, and corrective actions on electromechanical, pneumatic, and control systems
• Wire, commission, validate, build, and maintain industrial control panels and field devices to NFPA 79 and UL 508A standards; replace like-for-like components (power supplies, relays, fuses, terminal blocks, sensors), restore wiring condition, and create accurate redlines
• Navigate and diagnose PLCs, HMIs, alarms, permissives, sequences, I/O status, and logic behavior; clear approved alarms, perform basic recovery, capture evidence, and support minor authorized parameter adjustments with documentation
• Set up, diagnose, replace, and validate sensors, instrumentation, and industrial networks serving chillers, CDUs, pumps, and power distribution; verify signals, alignment, scaling, and network health
