Staff Mechanical Operator

Required

• The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
• 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.
• You 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.
• Physical Requirements
• Work in non-climate-controlled environments, including active construction areas, data halls, electrical and mechanical rooms, and outdoor spaces. Temperatures can be high or low, and conditions can be humid, loud or dusty.
• Lift, carry, push and pull up to 40 pounds on your own.
