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.

We're seeking a Construction Commissioning Manager to lead the integrated commissioning of critical electrical and mechanical systems for high-performance data centers. This role is responsible for commissioning planning and execution across power distribution, backup power, controls, HVAC, chilled-water systems, liquid cooling infrastructure, and associated piping—from installation verification and pre-functional testing through startup, functional performance testing, integrated systems testing, and final handover.

As the senior field leader for both disciplines, you will direct commissioning engineers, supervisors, technicians, vendors, and subcontractors; coordinate closely with construction, engineering, operations, and client stakeholders; and ensure all systems operate safely, reliably, and as an integrated whole. Success in this position requires strong technical knowledge of both electrical and mechanical infrastructure, disciplined issue resolution, and a consistent focus on safety, quality, schedule, and operational readiness.

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.

• High school diploma or equivalent required;
  Bachelor's degree in Electrical Engineering, Mechanical Engineering, Construction Management, or a related field preferred, or equivalent relevant field experience.
• Minimum of 7 years of progressive experience in commissioning, construction management, or system startup, including at least 3 years supporting data center or other mission-critical facility projects.
• Demonstrated experience leading the commissioning of both electrical and mechanical infrastructure on complex, highly available facilities.
• Strong working knowledge of critical electrical systems, including switch gear, UPS systems, PDUs, generators, transfer equipment, busway, emergency power, controls, protection systems, and redundant power architectures.
• Strong working knowledge of critical mechanical systems, including HVAC, chilled-water systems, pumps, piping, heat rejection, plumbing, liquid cooling, and data center environmental controls.
• Experience with liquid cooling technologies used in high-performance computing environments, such as direct-to-chip cooling, coolant distribution units, or immersion cooling.
• Proficiency in interpreting electrical one-lines, mechanical drawings, P&IDs, control diagrams, sequences of operation, commissioning scripts, equipment submittals, and change-management plans.
• Knowledge of applicable commissioning, electrical, mechanical, safety, and quality standards and best practices, including NEC, NFPA 70E, IEEE, OSHA, and relevant mechanical codes and standards.
• Familiarity with commissioning platforms, BMS, EPMS, and project management tools such as Procore, Primavera P6, Microsoft Project, and Microsoft Office Suite.
• Strong leadership, communication, technical writing, and stakeholder-management skills, with the ability to lead multidisciplinary teams in a fast-paced field environment.
• Excellent analytical and problem-solving skills, with a detail-oriented approach to safety, quality, documentation, schedule, and technical issue resolution.
• PMP, LEED AP, commissioning certification, or similar professional credentials are a plus.

• Pre-employment screening, including background check and substance testing may be required according to company policies.
• Must provide own steel-toed work boots;…
