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 moving to liquid-cooled GPU halls at high density. Reporting to the VP, Engineering, the Senior Mechanical Engineer owns the mechanical systems that move heat and fluid across our Canadian sites: chilled water plant, coolant distribution, pumps, piping, heat exchangers, chillers and the controls around them, from design through construction, commissioning and operation.
You do not need to have worked in a data center. We are looking for an engineer who has owned fluid systems end to end in a demanding environment (oil and gas, petrochemical, water treatment, marine, mining or industrial process are all good backgrounds) and who can bring that to a new problem. If your career has been in pumps, pipes, chillers and compressors rather than fans and ducts, this is the role for you.
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
- Serve as the owner's mechanical SME for cooling plant across design, construction, commissioning and operations of liquid-cooled HPC data centers: chilled water, coolant distribution, pumps, piping, heat exchangers and controls.
- Review and validate specifications, calculations, drawings and other technical deliverables from consultants, equipment manufacturers, engineering firms and commissioning agents.
- Lead or support construction, installation and commissioning activities for mechanical systems.
- Monitor mechanical system performance to maintain operating limits and reliability, assess current and future capacity constraints, and implement energy-efficient improvements.
- Collaborate with architects, electrical engineers and other stakeholders to ensure integrated design solutions.
- Support project planning by contributing to schedules, budgets and resourcing plans, and coordinating with site teams, corporate staff and external engineering partners.
- Develop technical documentation (plans, checklists, specifications, reports, procedures and standards) to support work from design through construction, commissioning and operations.
- Maintain records for cooling-system technical documentation and site integration, ensuring completeness, accuracy and availability.
- Coach and provide feedback to other staff on cooling, mechanical and piping matters.
- Perform technical analyses (calculations, simulations, CFD and thermal analysis) to optimize liquid and air cooling and airflow.
Requirements
- Bachelor's degree in Mechanical Engineering from a recognized institution. P.Eng or eligibility for registration with EGBC preferred.
- 7+ years designing, building, commissioning or operating fluid-moving mechanical systems: pumps, piping, chillers, compressors, heat exchangers, hydronic and process cooling plants.
- Data center or mission critical experience preferred. Liquid cooling exposure (direct-to-chip, coolant distribution units, rear-door heat exchangers) is a strong asset.
- Hands-on experience sizing pumps, piping, heat exchangers and chilled water plant, including hydraulic and thermal calculations.
- Working knowledge of P&IDs and plant design tools (AutoCAD, Revit or equivalent).
- Ability to apply CFD and thermal analysis results to design decisions.
- Working knowledge of ASHRAE (including TC 9.9), ASME B31 piping codes, CSA and BC codes. ASPE, IPC and IECC an asset. Familiarity with BMS/BAS or DCIM platforms an asset.
- Senior individual contributor who mentors and coordinates across disciplines, with the potential to lead a mechanical team as the group grows.
- Excellent verbal and written communication skills across audiences from junior staff to senior leadership.
- Self-driven, detail oriented, and comfortable delivering high-quality work with limited direction, uncertainty and limited information.
- Willing to travel regularly to Prince George and other IREN sites in BC, and Alberta in future.
