Job title: Design and Construction Mechanical Engineer, Korea

About the Role Design and Construction Mechanical Engineer, Korea serves as the Mechanical Engineering System subject matter expert for the design and construction of greenfield, brownfield, and colocation data centres in Korea. You will oversee mechanical design across the project lifecycle from concept through commissioning and handover, ensuring high-density AI workloads are supported and sites operate at peak performance.

What You'll Do

• Lead mechanical designs in coordination with other disciplines to produce a complete construction document package.
• Drive innovation and R&D for emerging technologies (e.g., liquid cooling integration, advanced monitoring).
• Participate in site selection reviews and define site utility requirements with local utilities.
• Design and develop Mechanical systems for data centres (ACMV, hydraulic, thermodynamics, refrigeration cycle, Fire Protection, Plumbing & Sanitary, etc.).
• Perform engineering calculations (cooling load, hydraulic), equipment sizing (chillers, pumps, cooling towers, AHUs, heat exchangers) and procure equipment meeting safety and performance standards.
• Leverage experience with large-scale chilled water plants, liquid cooling systems, cooling towers, and chemical dosing.
• Ensure designs meet quality and budget targets; collaborate with regional vendors and manufacturers.
• Ensure compliance with APAC design codes and jurisdictional requirements; review equipment submittals.
• Manage multiple concurrent projects across geographic regions; define scope and provide technical support pre/during construction.
• Conduct feasibility studies, value engineering, and testing with commissioning teams to validate installations.
• Perform root cause analysis and implement corrective actions for mechanical issues.
• Update internal design specifications and drawings with lessons learned; travel to sites in Korea to work with field engineers and support startups.

What We're Looking For

• Bachelor’s degree in Mechanical Engineering.
• 7–10+ years designing and maintaining mechanical systems for data centers; 5+ years in mission-critical facilities.
• Knowledge of large-scale mission-critical mechanical infrastructure.
• Experience with high-density AI/HPC workloads.
• Licensed Professional Engineer (PE) or Chartered Engineer is an advantage.
• Strong fundamentals in thermodynamics, fluid mechanics, heat transfer, fire protection, plumbing and sanitary systems.
• In-depth knowledge of critical data center electrical systems.
• Proven ability to research and implement new designs from concept through deployment.
• Experience managing supplier relationships and FATs.
• Proficiency with AutoCAD, Revit, BIM; ability to work on multiple projects across regions.
• Willingness to travel within Korea for site reviews.
