Mechanical HVAC Commissioning Lead DATA CENTER USA (J26-333)

Industry: IT / Critical Infrastructure

Location: USA

Context

The Mechanical / HVAC Commissioning Lead is responsible for the commissioning and validation of all thermal management systems within a data center. This role ensures that critical cooling infrastructure operates reliably under all conditions, preventing server overheating and guaranteeing continuous IT load availability.

The position plays a key role in verifying that the cooling plant can sustain full heat rejection capacity during peak data center utilization.

Key Responsibilities

• Lead commissioning activities for all mechanical and HVAC systems
• Develop and execute commissioning plans, test procedures, and validation scripts
• Verify performance of cooling systems under full and partial IT load conditions
• Ensure proper integration between BMS and HVAC control systems
• Validate redundancy and resilience strategies (N+1, 2N cooling architectures)
• Supervise contractor and vendor commissioning activities

Critical Testing Activities

Thermal Load Validation

• Confirm cooling capacity meets design IT heat load requirements
• Test system behavior under peak server utilization scenarios
• Validate temperature and humidity stability in data halls

System Performance Testing

• Chiller efficiency and sequencing tests
• CRAH/CRAC airflow balancing and control verification
• Pump staging and differential pressure control validation
• Cooling tower performance and heat rejection efficiency checks

 Failure Scenario Testing

• Simulate equipment failure and redundancy activation
• Validate automatic switchover of cooling loops
• Ensure uninterrupted cooling during component outages

Technical Requirements

• Strong experience in HVAC systems for critical environments
• Deep knowledge of chilled water systems and thermal dynamics
• Experience with data center cooling architectures
• Understanding of BMS integration and control sequences
• Familiarity with commissioning tools, sensors, and balancing procedures
• Knowledge of ASHRAE data center environmental standards

Candidate Profile

• Degree in Mechanical Engineering, HVAC Engineering, or equivalent
• Proven experience in data center or mission-critical facility commissioning
• Strong background in large-scale cooling plant systems
• Experience with commissioning, testing, and troubleshooting HVAC systems
• Ability to work in multidisciplinary engineering environments
• Strong analytical mindset with attention to operational reliability
