Mechanical Systems Expert

ABOUT THE ROLE: The Mechanical Systems Expert is Managed Services' expert embedded in a data center build - supporting design review and commissioning to ensure cooling systems are operable and maintainable at turnover. Every design decision eventually becomes someone's 3 a.m. problem; this role reviews the design and witnesses the testing on behalf of that person. Some of the key responsibilities you should expect are the following: Operability Design ReviewReview mechanical and cooling designs - chilled water plants, air and liquid cooling systems, CDUs, CRAHs, heat rejection, water treatment - through an operations lens: maintenance access and laydown, isolation and redundancy behavior, degraded-mode operation, instrumentation adequacy, and failure-mode consequences. File review comments that change designs, not just document concerns. Construction-Phase VerificationWalk mechanical installations at key milestones: pipe routing and support, valve access, equipment clearances, insulation quality, and cleanliness/flushing protocol compliance - catching operability problems while they're still cheap to fix. Commissioning WitnessWitness Level 3-5 commissioning of mechanical systems: functional performance tests, staging and failover sequences, failure scenarios, and integrated systems testing. Drive operational issues into the Cx log with clear acceptance criteria and verify closure personally. Turnover ReadinessVerify mechanical turnover packages: O&M, as-builts, valve tags and system labeling, water treatment baselines, spare parts and consumables lists, and PM program inputs (frequencies, procedures, vendor contacts). Validate training actually equips operators to run the plant. Operations Transition SupportSupport early operations stabilization post-turnover: alarm tuning input, setpoint refinement, and first-months troubleshooting alongside the operations team. Program FeedbackFeed operational lessons into Hut 8 mechanical design standards and the next project's basis of design.
