Senior Mechanical Operator - Data Center Cooling

Fluidstack; Abernathy (TX); On-site; USD 120,000 - 180,000; Full time

Job summary

Fluidstack seeks an experienced Data Center Mechanical Operations Lead to manage live, always-on cooling systems in our hyperscale facilities. You will own mechanical operations on shift, drive maintenance, and lead root-cause analysis to prevent outages while ensuring safety and compliance.

You will work with chiller plants, CRAC/CRAH, pumps, and hydronic loops, mentor junior staff, and help refine SOPs for fast-scaling, high-uptime environments across multiple sites.

Qualifications

• 8+ years of hands-on mechanical or critical facilities operations in data centers.
• Deep knowledge of chillers, cooling towers, CRAC/CRAH units, air handlers, pumps, and hydronic loops.
• Fluency in BMS platforms: reading trends, tuning alarms, diagnosing faults from controls data.

Responsibilities

• Own mechanical operations on shift as the top escalation point for chiller plant, CRAC/CRAH, air handler, pump, and cooling loop failures in a live, always-on facility.
• Run preventive maintenance execution end to end: scheduling, vendor supervision, lockout/tagout, and QA of completed work, with records rigorous enough to survive a customer or owner audit.
• Lead root-cause analysis for mechanical incidents and drive corrective actions to closure, including procedure updates, setpoint changes, and spare parts adjustments.
• Build and maintain operating procedures (SOPs, MOPs, EOPs) for mechanical systems, and drill them so any operator on shift can execute under failure conditions.
• Drive BMS alarm hygiene and trend analysis so degrading equipment gets caught and fixed before it trips, not after.
• Close out commissioning-to-operations handovers for new mechanical plant, verifying performance against design before accepting systems into the maintenance program.
