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.
