Commissioning Manager, Mechanical

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. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants.

There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it. We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software.

Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We are seeking a Commissioning Manager, Mechanical Data Centers with experience leading chilled water, HVAC, and overall mechanical commissioning efforts for our high-performance Data Centers. This role requires a deep understanding of pre-commissioning and commissioning across all commissioning phases (Level 1–5) for mechanical systems. The role will require stakeholder coordination while acting as the Owner’s Commissioning Mechanical lead for general contractors, designers, and vendors across multiple projects/sites.
