About the role

ABOUT FLUIDSTACK We exist to make humanity more free.
For most of human history, you farmed or you starved.
Technology gave people more time for the things they wanted to do, instead of things they had to do.

Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
Velocity. We drive everything forward as fast as possible.
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.
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.

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.
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.

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.
Fluidstack is an Equal Employment Opportunity Employer.
Fluidstack will consider for employment qualified applicants with arrest and conviction records pursuant to applicable law.
You will receive a confirmation email once your application has successfully been accepted.

Operate live chiller plants, CRAC/CRAH units, and direct-to-chip liquid cooling loops at densities where minutes of cooling loss mean thermal shutdown of GPU clusters.
Build preventive and predictive maintenance programs that scale across new sites without adding downtime or headcount linearly.
Take mechanical systems from commissioning handover to steady-state operations on compressed schedules, closing punch-list and performance gaps before they become incidents.
Run root-cause analysis on mechanical failures and feed corrective actions back into design, operating procedures, and spare parts strategy.
