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 are seeking a Construction Superintendent - Mechanical to lead the installation and integration of advanced mechanical systems—including liquid cooling technologies, piping, pumps, and HVAC—in high-performance data center environments. This role requires hands-on supervision, cross-trade coordination, and a strong focus on safety, quality, and schedule adherence. The ideal candidate brings 7+ years of mechanical construction experience, including work with liquid cooling systems, and excels at team leadership, technical problem-solving, and ensuring compliance with project specifications and industry standards.

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.   

Responsibilities

• Lead, mentor, and supervise a team of mechanical technicians, fitters, and subcontractors working on liquid cooling systems (e.g., direct-to-chip cooling, rear-door heat exchangers), piping, pumps, valves, and HVAC systems.
• Monitor performance and ensure workforce compliance with project goals and safety standards.
• Oversee the installation of mechanical systems, ensuring compliance with project drawings, specifications, and manufacturer guidelines.
• Coordinate with other trades (electrical, plumbing, structural) to ensure seamless integration of liquid cooling systems.
• Collaborate with engineers, vendors, and QA/QC teams to resolve technical issues and maintain project milestones.
• Ensure all mechanical installations meet data center standards, industry codes, and client requirements.
• Verify material and equipment compliance with approved submittals.
• Support QA/QC inspections and address non-conformance issues promptly.
• Supervise pressure testing, flushing, and balancing of liquid cooling loops to ensure leak-free operation and optimal performance.
• Oversee functional and performance testing of cooling systems to meet thermal and flow rate specifications.
• Assist commissioning teams in validating system performance under operational conditions.
• Enforce OSHA regulations, site-specific safety protocols, and industry best practices.
• Conduct regular safety audits and ensure team compliance with personal protective equipment (PPE) and safe work practices.
• Investigate and report incidents, implementing corrective actions to prevent recurrence.
• Monitor work schedules to meet project deadlines, coordinating with the project management team.
• Track progress and update project management on mechanical system status.
• Manage material and equipment inventories to prevent delays.
• Provide technical guidance on liquid cooling system installation, maintenance, and troubleshooting.
• Address field challenges, such as design conflicts or equipment malfunctions, with practical solutions.
• Stay updated on advancements in liquid cooling technology and data center mechanical systems.

Requirements

• High school diploma or equivalent; Associate’s or Bachelor’s degree in Mechanical Engineering, Construction Management, or related field preferred.
• Minimum 7 years of experience in mechanical construction or supervision in industrial projects, with at least 3 years of experience working with liquid cooling systems in data centers or similar high-tech facilities.
• Journeyman or Master Mechanical License, AWS Certified Welding Inspector (CWI), or equivalent.
• OSHA 30 certification required: First Aid/CPR certification a plus.
• Proficiency in reading and interpreting mechanical drawings, P&IDs, and specifications.
• In-depth knowledge of liquid cooling technologies, heat transfer principles, and data center infrastructure.
• Familiarity with testing tools (e.g., pressure gauges, flow meters, thermal imaging equipment).
• Strong leadership, communication, and conflict-resolution skills.
• Ability to manage multiple priorities and work under pressure.
• Detail-oriented with excellent problem-solving abilities.

Other important requirements:  

• Pre-employment screening, including background check and substance testing may be required according to company policies.
• Must provide own steel-toed work boots; other PPE will be supplied.
• Must be able to reliably commute to the work site daily or have plans to relocate before starting work.
• Must be comfortable working a rotational schedule, which includes day and night shifts as well as weekend work, based on project needs.
• Employees working night shifts will receive a 15% premium added to their hourly rate only for hours worked during night shifts.
