Job description

The Engineer – Mechanical Design – Data Centre is a full-time role based in Singapore or Indonesia (Batam).

The role reports to the Senior Manager – Data Centre.

Overview

The Engineer – Mechanical Design is responsible for the design, technical governance and engineering support of mechanical infrastructure across the company’s data centre portfolio. The role supports the full asset lifecycle – from concept design and construction through commissioning, operations, upgrades and capacity expansion – to ensure facilities meet the highest standards of availability, reliability, scalability, sustainability and operational efficiency.

Working closely with internal design, construction, operations and commissioning teams, the Engineer – Mechanical Design will develop and review mechanical engineering solutions that support mission-critical environments while ensuring compliance with company design standards and industry best practices.

Key responsibilities

• Develop, review and approve mechanical system designs for new data centre developments and major facility expansions.
• Prepare and review engineering calculations, technical specifications, equipment schedules and design documentation.
• Design and optimise mission-critical cooling systems, including:
• Chilled water plants.
• Air-cooled and water-cooled systems.
• CRAH/CRAC systems.
• In-row and overhead cooling solutions.
• Cooling towers.
• Pumping systems.
• Mechanical piping networks.
• Ventilation and pressurisation systems.
• Perform cooling load calculations, hydraulic analyses and equipment sizing.
• Evaluate innovative cooling technologies, including liquid cooling solutions for high-density AI and HPC deployments.
• Develop standardised design guidelines and engineering specifications across the data centre portfolio.

Design Review & Technical Governance

• Review consultant and contractor designs to ensure compliance with company standards, project requirements and applicable codes.
• Participate in design reviews, HAZOP, constructability reviews, value engineering and technical risk assessments.
• Ensure mechanical designs support maintainability, operational resilience, energy efficiency and future scalability.
• Manage technical deviations and engineering change requests.

Project Delivery

• Support project teams throughout design, procurement, construction, commissioning and handover.
• Review technical submissions, vendor proposals, equipment selections and shop drawings.
• Participate in Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), Integrated Systems Testing (IST) and commissioning activities.

Operations & Asset Lifecycle Support

• Provide engineering support for operating data centres.
• Evaluate plant performance and recommend improvements to reliability, capacity and energy efficiency.
• Support root cause analysis (RCA) of mechanical failures and develop corrective actions.
• Plan infrastructure upgrades, equipment replacement and capacity expansion while maintaining operational continuity.
• Collaborate with operations teams to optimise preventive maintenance strategies and improve asset reliability.

Sustainability & Innovation

• Support initiatives to improve Power Usage Effectiveness (PUE), Water Usage Effectiveness (WUE), and overall facility sustainability.
• Evaluate emerging cooling technologies, energy-efficient equipment and digital engineering solutions.
• Promote standardisation, automation and continuous improvement across the mechanical engineering function.

Qualifications & experience

• Bachelor’s Degree in Mechanical Engineering or equivalent.
• Minimum 5 years of relevant experience in mechanical design of mission-critical facilities, with significant exposure to hyperscale or enterprise data centres.
• Experience working for a data centre owner/operator, engineering consultancy or EPC contractor delivering large-scale mission-critical projects.
• Professional Engineer (PE), Chartered Engineer (CEng) or equivalent professional registration is preferred.
• Strong knowledge of mission-critical HVAC systems and precision cooling technologies.
• Experience in chilled water system design, hydraulic balancing and pumping system optimisation.
• Knowledge of data centre cooling strategies, including hotaisle/cold aisle containment, free cooling, economisation, liquid cooling, high-density rack cooling.
• Understanding of mechanical redundancy philosophies (N, N+1, 2N, 2N+1).
• Familiarity with ASHRAE Thermal Guidelines, SMACNA, NFPA, ASME and relevant local building codes.
• Experience with CFD analysis and airflow optimisation is advantageous.
• Proficiency in AutoCAD, Revit MEP, Navisworks and BIM coordination.
• Experience with engineering software such as HAP, IES VE or equivalent.
• Understanding of commissioning methodologies and integrated systems testing for mission-critical facilities.
• Familiarity with Building Management Systems (BMS) and Data Centre Infrastructure Management (DCIM) platforms is desirable.
