We believe that human progress is invaluable, but it should be done in the right way: responsibly, sustainably and having a positive impact on the communities we operate in.

This position is based on-site in Canal Flats, BC, supporting the construction of a 30 MW liquid-cooled AI data center campus. It is a camp-based role working a 14 days on / 7 days off (14&7) rotation in support of the project's 24-hour, two-crew (A/B) construction schedule. Camp accommodations, meals, and site transportation are provided during on-rotation periods.

The Role

The General Foreman – Mechanical is the Superintendent's eyes and ears on the mechanical scope. Working under the direction of the Superintendent, you provide day-to-day oversight of the contractors executing liquid cooling and air cooling infrastructure, process piping, HVAC, fire suppression, plumbing, and associated equipment installation on IREN's 30 MW data center project in Canal Flats, verifying that work is performed safely, in the right sequence, to the approved drawings and specifications, and in line with the project quality process. This is a mission-critical build: you hold contractors to a zero-defect standard, escalate issues early, and spend the majority of every shift in the field as the primary daily point of contact for contractor foremen and site supervision.

• Daily Contractor Oversight: Conduct daily walkdowns of all active work areas to confirm crews are working to the current plan, drawings, and specifications; verify contractor manpower, equipment, test equipment, and material readiness against the three-week look-ahead and report shortfalls to the Superintendent.
• Coordination: Coordinate mechanical work fronts, access, laydown, and equipment set (pumps, heat exchangers, CDUs, dry coolers, chillers, tanks, air handlers, fan walls, fire suppression equipment) with other trades to avoid conflicts and trade stacking.
• Permits & Controls: Confirm that permits, hazard assessments, lockout/tagout, hot-work, confined-space, and pressure-test exclusion zones are in place before mechanical work proceeds.
• Quality Process Oversight: Enforce the project Quality Management Plan and discipline Inspection and Test Plans (ITPs) in the field, including hold points, witness points, and required sign-offs. Perform first-hand verification of installations covering: technology cooling and facility water system piping (welded, grooved, pressed, and fused joints); liquid cooling infrastructure including CDUs, pumps, heat exchangers, dry coolers, filtration, and chemical treatment; pipe supports, hangers, anchors, expansion provisions, and seismic restraint; air cooling systems including air handling units, fan walls, evaporative or DX cooling, ductwork, dampers, and aisle containment interfaces; fire suppression including sprinkler and pre-action piping, clean-agent systems, detection interfaces, and fire pumps; plumbing, fuel systems, and equipment anchorage and alignment.
• Testing & Inspections: Witness and verify hydrostatic and pneumatic pressure tests, weld inspection and NDE records, flushing, cleaning and passivation, fill and chemical treatment, duct leakage and airflow testing, fire suppression acceptance tests, and equipment alignment and vibration checks; coordinate Technical Safety BC boiler and pressure vessel inspections and AHJ fire suppression acceptance; confirm records are complete before work is insulated, covered, or turned over.
• Non-Conformance: Identify, document, and track non-conformances and deficiencies; drive contractors to timely, verified closure and confirm rework meets specification; support the Engineers of Record in obtaining the field-review evidence required for BC Building Code letters of assurance.
• Contractor Supervision Interface: Act as IREN's primary daily field contact for contractor general foremen, foremen, and site supervisors; lead daily plan-of-day meetings; resolve field issues promptly and escalate schedule, quality, or safety concerns with recommended solutions; hold contractors to housekeeping and site-logistics standards appropriate to a mission-critical facility.
• Safety Leadership: Model and enforce IREN's safety culture and WorkSafeBC OHS Regulation requirements across all contractor crews; lead toolbox talks and field-level hazard assessments; stop work where conditions present an unacceptable risk.
• Documentation & Reporting: Maintain daily field logs, photo records, progress notes, and deficiency tracking; support the Superintendent with RFI follow-up, field changes, and as-built markups; contribute to weekly progress and quality reporting.

• 10+ years of hands-on industrial mechanical or piping construction experience (data centers, power generation, oil and gas, mining, pulp and paper, or heavy industrial), including 3+ years as a foreman, general foreman, or equivalent supervising mechanical contractor crews.
• Strong working knowledge of process piping, pumping systems, heat exchangers, HVAC and air handling, fire suppression, and equipment installation; able to read P&IDs, isometrics, mechanical drawings, equipment schedules, and specifications.
• Familiarity with ASME B31 piping codes, CSA B51, NFPA 13, 25, 72 and 2001, BC Building and Fire Codes, and WorkSafeBC OHS Regulation. A Red Seal pipefitter, steamfitter, plumber, millwright, or sheet metal ticket is an asset; equivalent industrial field experience will be considered.
• Demonstrated experience enforcing quality programs, ITPs, and inspection hold points on industrial projects.
• Strong communication skills and the ability to deal firmly and professionally with contractor supervision.
• Proficiency with common construction software (Procore or similar), Microsoft Office, and mobile field-inspection tools.
• Valid driver's licence and legal eligibility to work in Canada.
• Ability to work on-site in Canal Flats, BC on a 14&7 camp rotation, including night shift coverage as the project ramps; camp/remote-site experience an asset.

Preferred Experience

• Direct experience with liquid-cooled data center infrastructure (CDUs, direct-to-chip or immersion cooling) and its water quality, flushing, and cleanliness requirements.
• Experience with high-volume air-cooled installations (fan walls, evaporative cooling, aisle containment) and with sprinkler, pre-action, and clean-agent acceptance testing.
• Experience with start-up, air and water balancing, commissioning, and IST of critical cooling systems; familiarity with Technical Safety BC pressure piping registration.
• Gold Seal Certification, CSTS-2020 or BCCSA safety training, and standard first aid.
• Experience working on remote industrial sites in British Columbia or similar environments.

• Work with state-of-the-art AI hardware and some of the most advanced compute systems in the world
• Be part of a team that values innovation, autonomy, and continuous learning
• Make a measurable impact on the performance and reliability of global AI workloads
