About IR Pros

IR Pros provides commissioning, engineering, construction, and technical services for complex industrial and mission-critical environments. Our commissioning professionals bring extensive field experience supporting systems from initial equipment verification and installation through startup, functional performance testing, integrated systems testing, documentation, and final turnover.

IR Pros follows a comprehensive Levels 1–5 commissioning process, helping ensure critical cooling systems are properly installed, started, tested, integrated, and operating according to design requirements.

As IR Pros continues to expand within the data center market, we are looking for experienced commissioning professionals who understand the cooling infrastructure required to support today's high-density, mission-critical facilities.

Position Overview

IR Pros is seeking an experienced Data Center Commissioner specializing in mechanical and cooling systems for mission-critical data center environments. This position will be responsible for commissioning critical cooling infrastructure throughout the project lifecycle, from equipment installation and startup through Functional Performance Testing (FPT), Integrated Systems Testing (IST), and final turnover.

The ideal candidate has 3–6+ years of data center commissioning experience with a strong understanding of mechanical cooling systems and their associated controls. This is a hands‑on, field‑focused commissioning position requiring strong troubleshooting skills and the ability to coordinate effectively with clients, contractors, engineers, controls teams, equipment manufacturers, and other commissioning professionals.

Data Center Cooling Systems

• Chilled-water systems
• Air‑cooled and water‑cooled chillers
• Cooling towers and heat‑rejection systems
• Primary and secondary chilled‑water pumps
• Condenser‑water systems
• CRAH and CRAC units
• Computer‑room cooling systems
• In‑row cooling systems
• Air‑handling and ventilation systems
• Heat exchangers
• Pumps, valves, actuators, VFDs, and associated mechanical equipment
• Building Management Systems (BMS)
• Mechanical controls and sequences of operation
• Temperature, pressure, flow, and humidity monitoring
• Redundant cooling systems and failure/recovery sequences
• Liquid cooling and high‑density data center cooling systems, where applicable

Levels 1–5 Commissioning

Level 1 – Factory & Equipment Verification Review equipment submittals, specifications, sequences of operation, factory testing documentation, and commissioning requirements.

Level 2 – Installation Verification Perform field inspections and pre‑functional checks to verify cooling equipment, piping, controls, instrumentation, and supporting systems are properly installed and ready for startup.

Level 3 – Startup & Pre‑Functional Testing Coordinate equipment startup with contractors and manufacturers. Verify controls, sensors, valves, VFDs, safeties, alarms, interlocks, and system operation.

Level 4 – Functional Performance Testing (FPT) Execute functional testing of cooling systems under multiple operating conditions to verify performance against design intent and sequences of operation.

Level 5 – Integrated Systems Testing (IST) Support and execute integrated testing of mission‑critical cooling infrastructure, including equipment failures, loss‑of‑power scenarios, redundancy, automatic transfer, recovery sequences, and system response under simulated data center operating conditions.

What We're Looking For

We're looking for a commissioner who understands cooling systems — not simply someone who has worked around data centers. The right candidate understands how mission‑critical cooling systems operate as an integrated system, can troubleshoot problems in the field, understands sequences of operation and controls, and can verify that equipment performs properly during normal operation as well as failure and recovery scenarios.

Experience with large‑scale hyperscale, colocation, cloud, or other mission‑critical data center environments is highly preferred.

Join IR Pros

IR Pros is expanding its commissioning capabilities within the rapidly growing data center market. This position provides the opportunity to work on complex, high‑performance cooling infrastructure supporting some of today's most demanding mission‑critical environments.

If you have strong mechanical commissioning experience and understand what it takes to keep a data center cool, reliable, and operational, we want to hear from you.
