Data Center Commissioner – Cooling SystemsIR Pros | Fully Remote, Anywhere in the US | Data Centers / Mission Critical Full-Time |Fully Remote |Project-Based Travel | Data Centers / Mission Critical About IR ProsIR 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.
