HVAC Engineer (Senior/Principal)

About Our Client Our client is a global engineering organization focused on delivering modular and prefabricated data centre infrastructure solutions across Asian markets. Job Summary This position requires an HVAC specialist to oversee the complete engineering lifecycle of cooling systems for prefabricated data centre modules. You will be responsible for translating thermal requirements into factory-ready manufacturing documentation while driving the standardization of cooling technologies for both local and international deployments. Key Responsibilities Create comprehensive HVAC system configurations for modular units, producing precise fabrication drawings and detailed material lists for production. Execute thermal load assessments and computational fluid dynamics (CFD) analyses to verify system performance and enhance energy efficiency in specific project designs. Identify and integrate key cooling components, including chillers, cold distribution units, pumps, towers, and humidity control devices, ensuring they fit within the prefabricated module constraints. Offer technical expertise during the manufacturing process and on-site commissioning to troubleshoot and resolve any cooling-related technical challenges. Align technical specifications and equipment parameters with stakeholders, including clients, external consultants, general contractors, and equipment suppliers. Drive the standardization of HVAC design methodologies by managing drawing templates, maintaining version control, and overseeing document archiving for modular products. Requirements Hold a bachelor’s degree or higher in HVAC, refrigeration, energy systems, or a closely related engineering field. Possess at least three years of professional experience in HVAC design, with a strong preference for candidates who have contributed to data centre or construction projects. Demonstrate a thorough understanding of applicable HVAC design codes and standards, particularly those governing data centre facilities. Show proficiency in selecting and applying equipment from leading manufacturers, with a solid grasp of their performance metrics. Possess advanced capabilities in CAD software for creating technical drawings and documentation. Exhibit strong ownership of tasks, effective communication skills, and the ability to collaborate within a team environment. Have experience with micro-module or E-house data centre projects, which is highly desirable. Be familiar with international data centre construction standards, with prior exposure to overseas projects being a significant advantage. Be a Malaysian Chinese speaker capable of communicating fluently in Chinese. Be willing to undertake a six-month training and work period in Jinshan, Shanghai, before transferring to the manufacturing facility in Johor Bahru, Malaysia.
