Mechanical Systems Expert

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 they're 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 project's basis of design.

ABOUT YOU

• 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.
