General Foreman - Commissioning (Canal Flats)

Are you Ready to Build the Future of AI Infrastructure?

If you’re energized by massive scale, deep technical complexity, and the opportunity to shape the next era of compute, this is your moment. Join a team where groundbreaking work meets competitive compensation, meaningful impact, and a chance to accelerate your career at the forefront of AI innovation. We want to meet you.

Why IREN?

IREN is a vertically integrated AI Cloud provider, delivering large-scale data centers and GPU clusters for AI training and inference. IREN’s platform is underpinned by its expansive portfolio of grid-connected land and power in renewable-rich regions across North America, Europe and APAC.

With 100% renewable energy, we build, own and operate our data centers and take pride in being at the forefront of sustainable solutions for the ever-evolving applications of high-performance compute. 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 – Commissioning is the Commissioning Superintendent's eyes and ears on the commissioning scope. Working under the direction of the Commissioning Superintendent, you provide day-to-day oversight of the contractors executing contractor, vendor, and third-party commissioning activities across electrical, mechanical, liquid cooling, air cooling, fire suppression, and controls systems during the transition from construction to operations 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.

What You Bring

• 10+ years of hands-on industrial construction, start-up, or commissioning experience (data centers, power generation, substations, oil and gas, mining, pulp and paper, or heavy industrial), including 3+ years as a foreman, general foreman, commissioning lead, or equivalent supervising contractor or vendor crews during start-up.
• Demonstrated experience executing or overseeing Level 1 to 5 commissioning, including pre-functional, functional, and integrated systems testing.
• Strong working knowledge of critical power (MV/LV, UPS, generators, PDUs), cooling (pumps, CDUs, heat exchangers, air handling), and controls (BMS/EPMS); able to read single-lines, P&IDs, sequences of operation, control schematics, and commissioning scripts. Familiarity with CSA C22.1, CSA Z462, ASME B31, NFPA fire protection standards, and WorkSafeBC OHS Regulation; proficiency with Procore, CxAlloy, or similar.
• 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

• Prior commissioning of mission-critical or data center facilities, including liquid-cooled infrastructure (water quality, flushing, cleanliness) and high-volume air-cooled systems.
• Load bank testing, protective relay coordination, and pull-the-plug IST experience; fire suppression acceptance testing in mission-critical environments.
• Familiarity with NETA, ASHRAE commissioning guidelines, and Technical Safety BC processes.
• 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.

What You'll Do

• 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 Commissioning Superintendent.
• Coordination: Coordinate commissioning work fronts, system isolations, temporary power, load banks, and outage windows with construction crews still completing adjacent work, avoiding conflicts between construction and live or energized systems.
• Permits & Controls: Confirm that energization permits, MOPs, lockout/tagout, arc-flash controls, pressure-test exclusion zones, and construction-to-commissioning ownership hand-offs are in place before any activity 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: Level 1-2: factory witness test follow-up, receipt inspection, installation verification, and construction-completion checklists; Level 3: pre-functional testing, energization, start-up, and vendor commissioning of MV/LV switchgear, transformers, UPS, generators, PDUs, busway, pumps, CDUs, heat exchangers, dry coolers, air handlers, and fan walls; Level 4: functional performance testing of electrical, cooling, fire suppression, and controls, including sequence-of-operation and failure-mode testing; Level 5: Integrated Systems Testing under load bank and pull-the-plug scenarios, including BMS/EPMS alarming; fire suppression acceptance (sprinkler, pre-action, clean-agent) and interfaces to detection, shutdowns, and controls.
• Testing & Inspections: Witness and verify insulation resistance, protective relay and breaker testing, load bank testing, water and air balancing, flushing and water quality verification, and controls point-to-point checks; verify construction completion, punch-list closure, and turnover package readiness before releasing systems for start-up, and reject systems that are not ready; coordinate the third-party commissioning agent, Technical Safety BC, utility energization, and AHJ acceptance.
• 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.
