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 someones 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 Review

Review 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 Verification

Walk mechanical installations at key milestones: pipe routing and support valve access equipment clearances insulation quality and cleanliness/flushing protocol compliance - catching operability problems while theyre still cheap to fix.

Commissioning Witness

Witness 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 Readiness

Verify mechanical turnover packages: O&Ms 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 Support

Support early operations stabilization post-turnover: alarm tuning input setpoint refinement and first-months troubleshooting alongside the operations team.

Program Feedback

Feed operational lessons into Hut 8 mechanical design standards and the next projects basis of design.

ABOUT YOU

What were looking for:

- 8 years in critical facilities mechanical operations commissioning or chief-engineer-track roles.

- Deep hands-on knowledge of chilled water plants hydronic systems and data center cooling topologies - air-cooled water-cooled and liquid/direct-to-chip.

- Level 1-5 commissioning fluency from the witness/operations side including integrated systems testing.

- Sharp eye for maintainability in design reviews: access isolation and instrumentation gaps.

- Turnover documentation rigor - you read the O&M before signing for it.

- Comfortable embedded with a construction team while holding the operations line.

- Water treatment and cleanliness protocol experience for critical hydronic systems.

- CFC/EPA certifications trade licensure or engineering degree all welcome paths.

ABOUT THE WORK ENVIRONMENT

- Full time on-site role.
