Director, Data Centre Commissioning

Company Overview

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 an expansive portfolio of grid‑connected land and power in renewable‑rich regions across North America, Europe and APAC.

The Director, Data Center Commissioning will lead the development and standardisation of IREN’s liquid‑cooled, AI‑ready data‑center commissioning practices, ensuring world‑class delivery across a global portfolio of mission‑critical sites. This role owns the end‑to‑end commissioning lifecycle from best‑practice documentation and specification development through execution oversight, driving quality, repeatability and speed across multiple concurrent projects.

• Commissioning Strategy & Best Practices:
  Define and own IREN’s global data center commissioning strategy with a focus on liquid‑cooled and high‑density AI infrastructure—developing, documenting, and continuously improving commissioning best practices, SOPs, and specifications for direct‑to‑chip and CDU‑based architectures; establish a repeatable framework applicable across all regions and site typologies; integrate emerging standards (ASHRAE Guideline 1.6P, ASHRAE 90.4, NEC Articles 270/646) as the industry evolves.
• Liquid Cooling & High‑Density Systems:
  Lead commissioning validation for liquid cooling systems including CDUs, cold plates, immersion tanks, rear‑door heat exchangers, manifold distribution systems, and FDUs; oversee pressure testing, flow balancing, water quality management, and thermal performance validation for high‑density AI rack environments (150–600+ kW/rack); direct commissioning of medium‑voltage distribution systems (4.16 kV to 34.5 kV), UPS, BESS, and on‑site generation assets; ensure hybrid cooling environments are commissioned to the highest reliability standards.
• Multi‑Site Commissioning Management:
  Oversee commissioning activities across multiple concurrent project sites and global regions, maintaining consistent quality standards and delivery timelines; deploy and manage commissioning teams with remote and on‑site technical leadership across all phases; develop project‑specific commissioning plans, test scripts, and integrated systems testing (IST) protocols; manage project schedules, resource allocation, and commissioning budgets across the portfolio.
• Quality Assurance & Compliance:
  Establish and enforce quality assurance processes and acceptance criteria for all commissioned systems; ensure compliance with applicable codes and regulations across all operating regions (NEC, IEC, local authority requirements); drive sustainability compliance including PUE and WUE validation, energy efficiency certification (LEED, ASHRAE), and grid‑readiness verification; oversee FAT and SAT programmes with equipment vendors and manufacturers.
• Automation, Digital Tools & Smart Commissioning:
  Implement and standardise digital commissioning workflows using Common Data Environments (CDE), BIM (LOD 400/500), and DCIM platforms; integrate AI‑driven Fault Detection and Diagnostics (FDD) and Condition‑Based Maintenance (CBM) validation into commissioning scope; leverage automation tools, 3D laser scanning, and robotic verification to improve accuracy and reduce rework; ensure proper sensor placement, IoT integration, and digital twin alignment across all commissioned facilities.
• Cross‑Functional
  
  Collaboration:
  
  Partner closely with Engineering, Construction, Operations, and Procurement to align commissioning activities with project milestones and operational readiness requirements; collaborate with Innovation and Technology teams to incorporate new design standards into commissioning specifications; engage equipment vendors, specialist subcontractors, and third‑party commissioning agents; support procurement with technical input on commissioning‑related scopes, contracts, and vendor qualifications.
• Leadership & Team Development:
  Recruit, build, and lead a global commissioning organisation capable of executing across multiple project sites simultaneously; establish training and certification programmes to…
