Commissioning Project Engineer, Data Centers

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.

The Commissioning Project Engineer is responsible for planning, coordinating, and executing commissioning activities for data center and mission critical facility projects, with a primary focus on Factory Acceptance Testing (FAT) and the development, review, and approval of project test procedures. This role ensures all critical infrastructure systems — from power and cooling to controls and monitoring — are fully validated against design intent before energization and handover, protecting uptime, reliability, and client SLA commitments.

• Plan, schedule, and coordinate Factory Acceptance Tests (FATs) and Factory Witness Tests (FWTs) for mission critical equipment including UPS systems, generators, switch gear, PDUs, transformers, precision cooling units (CRACs/CRAHs/CDUs), BMS/EPMS controllers, and fire suppression systems
• Review and approve vendor-submitted FAT procedures prior to testing, ensuring alignment with project specifications, Uptime Institute Tier standards, and client-specific requirements
• Develop and distribute FAT schedules, witness notifications, and travel logistics for internal teams, client representatives, and third‑party commissioning agents (CxAs)
• Attend and lead witness tests at manufacturer facilities, documenting results, managing non-conformance reports (NCRs), and driving punch list resolution
• Ensure all test data packages, certificates of conformance, and factory test reports are complete and submitted per project documentation requirements
• Coordinate re‑test scheduling with vendors where equipment fails to meet acceptance criteria, managing impacts to overall project schedule

• Lead the review, development, and approval of Level 1 through Level 5 commissioning test procedures across all critical systems, including electrical distribution, standby power, mechanical cooling, controls, DCIM/BMS integration, and security/access systems
• Ensure procedures align with ASHRAE, TIA‑942, Uptime Institute, and applicable NEC/NFPA standards, as well as owner‑specified commissioning requirements
• Coordinate interdisciplinary procedure reviews with MEP engineers, IT infrastructure teams, controls specialists, and HSE representatives
• Maintain a master commissioning procedure register, tracking revision status, approval workflows, and issue‑for‑construction releases
• Issue approved procedures to field commissioning teams, providing technical clarification and support during integrated systems testing (IST) and critical load testing
• Identify and resolve conflicts between test procedures, engineering deliverables, and equipment submittals

• Track and report commissioning progress against project milestones, including shell & core readiness, critical path mechanical and electrical completions, and white space readiness
• Maintain commissioning databases, test records, and punch lists in commissioning management platforms (e.g., Cx Alloy, ICAT, Procore)
• Coordinate with procurement and equipment expediting teams to align vendor FAT dates with construction and fit‑out schedules
• Participate in commissioning readiness reviews, pre‑TAB meetings, and critical power energization planning
• Support the development of…
