Senior Data Center Mechanical Operator

Fluidstack; Austin (TX); On-site; USD 120,000 - 160,000; Full time

Job summary

Fluidstack is seeking a senior Data Center Mechanical Operations engineer to lead on-shift mechanical performance, troubleshoot chiller and cooling loop issues, and ensure continuous high-uptime operations at our Texas data centers. You will drive preventive maintenance, incident analysis, and procedural improvements in a fast-paced frontier compute environment.

Experience with large-scale cooling systems, direct-to-chip liquid cooling, and on-shift escalation will be highly valued.

Qualifications

• 8+ years of hands-on mechanical or critical facilities operations in data centers.
• Deep operating 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.
• 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.
