Mechanical Commissioning (HVAC & Water to Water Cooling) data centre

Our Client are currently looking for a Mechanical Commissioning (HVAC & Water‐to‐Water Cooling) for a Data Centre - expat assignment in India

Duration: 1-3 years

Location: based on site in India; Mumbai or Hyderabad

Monday to Friday, 8 hours per day

Rotation : 8 weeks on / 2 weeks off

Start date: spring 2026

7–12+ years experience in mechanical commissioning for critical facilities.

Role Purpose

Oversee the commissioning of all mechanical, HVAC, and water‐to‐water cooling systems for a hyperscale/enterprise datacentre in India. Ensure safe, compliant, and performance‐verified delivery of cooling infrastructure from plant to white space, achieving required redundancy, thermal stability, and operational readiness.

Key Responsibilities

Cooling Plant & HVAC Systems

- Oversee commissioning for HVAC systems, including AHUs, CRAHs/CRACs, MAUs, exhaust systems, pressurisation systems, and humidity control. - Commission water-to-water cooling systems, including: - Chillers (air‐cooled, water‐cooled, modular, or water‐to‐water units) - Cooling towers / dry coolers - Heat exchangers - Primary/secondary pumping systems - Glycol loops (if applicable) - Plate heat exchangers and economiser systems - Oversee system flushing, chemical cleaning, passivation, pressure testing, leak tests, and system balancing.

Performance & Controls

- Validate thermal performance: delta‐T, flow rates, capacity, and setpoint stability across all ambient conditions. - Commission HVAC control sequences including temperature, humidity, static pressure, free cooling, staging, and redundancy logic. - Work closely with BMS/Controls Lead to ensure all mechanical points, trends, alarms, and SOOs operate as designed.

Integration & Testing

- Ensure complete commissioning of: - Chilled water loops - CT/EC fan controls - Cooling distribution in whitespace - Pressure zoning - Heat rejection systems - Develop and execute functional performance tests (FPTs) and system-level tests. - Support Integrated Systems Testing (IST) by preparing load strategies, thermal load tests, and failure‐mode testing (pump failure, tower fan failure, chiller isolation, valve malfunction scenarios).

Documentation & Quality

- Maintain complete mechanical commissioning documentation: ITPs, test sheets, redlines, defect logs, and O&M integration. - Drive punch list closure for all mechanical/HVAC and cooling systems. - Ensure commissioning deliverables support operations handover: maintenance strategies, control strategies, spares, and training.

Required Experience

- 7–12+ years experience in mechanical commissioning for critical facilities. - Deep experience with: - HVAC systems in mission‐critical environments - Water‐to-water cooling systems (mandatory) - Chilled water systems (variable primary/secondary) - Cooling towers / dry coolers - CRAHs/CRACs / white space distribution - Demonstrated delivery of mechanical commissioning for datacentres or large industrial MEP projects. - Strong understanding of TAB, hydronic balancing, and controls optimisation.

Qualifications

- Degree in Mechanical Engineering or equivalent technical qualification. - Additional credentials in commissioning management, HVAC certifications, or critical environment training preferred. - Experience on international expat assignments, ideally in India or APAC regions.

Competencies

- Strong multi‐vendor coordination & orchestration. - Excellent root‐cause analysis for cooling and controls behaviours. - Strong documentation discipline and ability to enforce design intent.

Expat & India‐Specific Requirements

- Experience managing local contractors, OEMs, and BMS vendors in India. - Strong safety culture, especially in high‐risk commissioning environments. - Ability to work extended commissioning and IST windows as needed. - Willingness to travel to OEM factories for FAT and regional support.
