About the Role
Fluidstack is building civilization-scale infrastructure for AI, aiming to deliver 10 to 100s of GWs of compute faster than anyone else. We are looking for individuals who care deeply about this mission and want to contribute to expanding human freedom through AI.
Responsibilities
- Lead mechanical commissioning across flushing, cooling, heat rejection, and liquid cooling systems for high performance data centers, spanning Level 1 through Level 5 commissioning phases.
- Drive the Testing & Verification program for mechanical cooling, heat rejection, and data hall thermal systems, working with commissioning agents and engineers from pre-site testing through on-site functional testing.
- Own commissioning documentation across multiple projects and sites, tracking issues, test results, and reports with enough rigor to hold up under an owner audit.
- Run on-site commissioning operations across general contractors, designers, and vendors: inspections, safety enforcement, progress tracking, and issue resolution.
- Close out final operational handover for mechanical systems, confirming every system is ready for service before occupancy.
Requirements
- A minimum of 10 or more years of hands-on commissioning experience.
- Commissioned data center mechanical equipment firsthand: chillers, cooling towers, CRAH/CRAC units, AHUs, CDUs, direct-to-chip liquid cooling, pumps, hydronic piping, and BMS/BAS integration.
- Experience running hydronic flushing, cleaning, and pressure and hydrostatic testing on process piping.
- Familiarity with AABC/NEBB TAB standards sufficient to identify incorrect test results.
- Experience building and executing Testing & Verification programs end to end, from pre-site functional testing through on-site startup, troubleshooting, and support.
- Ability to contribute to design and constructability reviews with commissioning and operations in mind.
- Ability to maintain rigorous commissioning records, issue logs, and test reports.
- Experience managing multiple concurrent project sites (Bonus).
