Job Description:

We are looking for a highly motivated Mechanical Engineer to support the design, construction, commissioning, and operation of mission-critical data center facilities.

This role will be responsible for critical cooling infrastructure, HVAC systems, commissioning activities, operational reliability, and energy-efficiency initiatives that ensure our facilities achieve the highest levels of availability and performance.

Key Responsibilities:

Mechanical Design & Engineering

• Review and develop mechanical designs, calculations, specifications, drawings, and technical documentation for data center facilities.
• Support the design and review of HVAC and cooling infrastructure for mission-critical environments.
• Perform cooling load calculations and equipment capacity assessments.
• Review chilled water systems including chillers, pumps, piping networks, valves, heat exchangers, and associated equipment.
• Review air-side systems including CRAH/CRAC units, AHUs, ventilation systems, ductwork, dampers, and air distribution systems.
• Evaluate redundancy, maintainability, reliability, scalability, and operational performance requirements.
• Review P&IDs, control schematics, equipment layouts, and control sequences.
• Ensure compliance with applicable local and international engineering standards.

Critical Cooling Systems

• Provide engineering support for chillers, cooling towers, dry coolers, heat exchangers, pumps, CRAH/CRAC units, and chilled water systems.
• Support redundancy strategies including N+1, 2N, and distributed-redundant configurations.
• Validate cooling capacity requirements against current and future IT demands.
• Monitor key operating parameters including temperature, flow rates, differential pressure, and system performance.
• Support cooling optimization initiatives focused on energy efficiency and PUE improvement.
• Evaluate failure scenarios and ensure environmental conditions remain within operational requirements.
• Monitor mechanical installation activities and ensure compliance with approved drawings and specifications.
• Inspect installation of chillers, pumps, cooling towers, CRAH/CRAC units, AHUs, piping systems, valves, ductwork, insulation, and associated equipment.
• Review shop drawings, RFIs, technical submissions, equipment submittals, and method statements.
• Coordinate with electrical, architectural, structural, controls, and MEP teams throughout project delivery.
• Resolve technical and construction-related issues while ensuring maintainability and operational accessibility.
• Support pre-commissioning, commissioning, and startup activities for mechanical systems.
• Participate in FAT, SAT, functional testing, performance testing, and Integrated Systems Testing (IST).
• Support commissioning of chillers, pumps, cooling towers, CRAH/CRAC units, heat exchangers, and associated control systems.
• Verify chilled water flow, pressure, temperatures, and overall system performance.
• Review mechanical control sequences and failure-response scenarios.
• Participate in integrated testing of mechanical and electrical systems.
• Support simulated failure testing of redundant cooling infrastructure.
• Review commissioning reports, punch lists, deficiencies, and test documentation.

Operations & Maintenance

• Support operation and maintenance of critical cooling and HVAC infrastructure.
• Troubleshoot equipment failures, alarms, temperature excursions, pressure issues, and flow-related abnormalities.
• Conduct root-cause analysis and implement corrective actions.
• Review preventive, predictive, and corrective maintenance programs.
• Develop and maintain SOPs, MOPs, and EOPs.
• Monitor performance and identify opportunities for optimization and sustainability improvements.
