About the role

Role focused on owning mechanical operations, preventative maintenance, and incident response for live data center facilities, with emphasis on chiller plants, CRAC/CRAH units, cooling loops, and BMS-driven analytics within hyperscale environments.

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.

Qualifications

  • 8+ years of hands-on mechanical or critical facilities operations in data centers, with time at a hyperscale operator, colocation provider, or cloud data center operations team.
  • Deep operating knowledge of chillers, cooling towers, CRAC/CRAH units, air handlers, pumps, and hydronic loops, including startup, failover, and recovery under load.
  • Fluency in BMS platforms: reading trends, tuning alarms, and diagnosing faults from controls data rather than waiting for equipment to fail.
  • A track record owning root-cause analysis and preventive maintenance programs at scale, not just executing tickets someone else wrote.
  • Experience as the senior mechanical escalation point on shift, making calls during outages when the runbook runs out.
  • Willingness to work rotating shifts and carry on-call responsibility for mechanical outages.
  • Ability to operate calmly in high-uptime, fast-scaling environments where the plant you ran last quarter is half the size of the one you run now.
  • Bonus: experience with direct-to-chip liquid cooling and CDUs, CFC/HCFC refrigerant certification (EPA 608 Universal or equivalent), or a role in commissioning handover for new-build mechanical plant.
