Project Engineer (Mechanical) - Data Center

Job Position

Project Engineer (Mechanical) - Data Center

Job Responsibilities

• Lead and manage all on-site mechanical construction activities for data center projects, from installation through testing and commissioning.
• Mechanical Site Supervision: Manage on-site mechanical works, including chillers, cooling towers, CRAH/CRAC units, AHUs, pumps, and chilled water and condenser water piping, ensuring alignment with project plans, technical specifications, and timelines.
• Data Center Cooling Systems: Oversee installation of white-space cooling, including hot/cold aisle containment, in-row cooling, and liquid cooling solutions (CDUs, direct-to-chip, rear-door heat exchangers) for high-density racks.
• Piping, Fire Protection & Plumbing: Supervise fuel oil systems for standby generators, pre-action sprinkler and clean-agent gas suppression systems (e.g. FM-200, Novec 1230, inert gas), water supply, drainage, and leak detection interfaces.
• Construction Quality & Safety Compliance: Ensure all mechanical works comply with local and international standards (e.g. ASHRAE, NFPA, SMACNA) and safety protocols, including hot work, lifting, and confined-space permits.
• Testing & Commissioning: Witness pressure tests, pipe flushing and chemical cleaning, testing, adjusting and balancing (TAB), and Level 1–5 commissioning, including Integrated Systems Testing (IST) to verify cooling redundancy (N+1 / 2N).
• Technical Review & Problem-Solving: Review mechanical shop drawings, equipment submittals, and method statements; resolve clashes with civil and electrical trades through BIM/MEP coordination.
• Material & Equipment Management: Track, foresee, and address the availability of long-lead equipment (chillers, CRAHs, pumps, CDUs), from factory acceptance testing (FAT) through delivery and installation.
• Coordination & Communication: Work closely with the project team, contractors, consultants, vendors and key stakeholders to ensure smooth project execution.
• Progress Monitoring & Reporting: Track project milestones, prepare daily/weekly site reports, and provide updates to senior management and stakeholders.
• Stakeholder Liaison: Maintain effective communication with local authorities, subcontractors, and project teams to facilitate seamless operations 

Job Qualifications

• Bachelor’s degree in Mechanical Engineering or a related field. A Thai Professional Engineer license (COE) is a plus.
• Minimum 3-10 years of experience in mechanical works for large-scale infrastructure, industrial, power plant, or commercial building projects (experience in data center projects is a plus but not required).
• Strong technical knowledge of HVAC, chilled water and precision cooling systems, mechanical piping, and fire protection systems.
• Understanding of data center cooling concepts (thermal management, redundancy, PUE) and their interfaces with power systems and BMS controls. • Strong leadership, problem-solving, and cross-cultural communication skills.
