Role Scope- 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.
What We're Looking ForThe 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.- You have a minimum of 10 or more years of hands-on commissioning experience
- You've 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.
- You've run hydronic flushing, cleaning, and pressure and hydrostatic testing on process piping, and you know AABC/NEBB TAB standards well enough to catch a bad test result before it gets signed off.
- You've built and executed Testing & Verification programs end to end, from pre-site functional testing through on-site startup, troubleshooting, and support.
- You show up in design and constructability reviews with commissioning and operations in mind, catching issues before they're built into concrete and steel.
- You keep commissioning records, issue logs, and test reports rigorous enough that any of them could stand up to an owner or insurer audit.
- You hold a degree in Mechanical Engineering.
- Bonus: ASHRAE or BCxA commissioning guideline experience. Controls or electrical systems knowledge. Hyperscale or mission-critical data center project experience. Managing multiple concurrent project sites.
Benefits- Competitive total compensation package (salary + equity).
- Retirement or pension plan, in line with local norms.
- Health, dental, and vision insurance.
- Generous PTO policy, in line with local norms.
We are committed to pay equity and transparency.
