Job description

Our client is a Malaysian entity dedicated to the development and operation of data centre infrastructure.

Job Summary

This position focuses on directing the thermal engineering strategy for high-density GPU environments, specifically integrating liquid cooling solutions. The role requires bridging the gap between facility-level infrastructure and server-side thermal management to guarantee efficient heat rejection.

Key Responsibilities

• Assess HVAC configurations and liquid cooling architectures to verify they meet the thermal demands of high-power GPU racks, while confirming equipment specs and long-term scalability.
• Oversee the technical integration of GB-series liquid cooling circuits with building systems, managing coolant distribution, piping, rack interfaces, water quality, and leak prevention measures.
• Lead the selection and procurement of critical equipment, including the review of vendor documentation, monitoring of production schedules, and execution of final acceptance tests.
• Monitor on-site construction quality and progress, resolving cross-disciplinary technical issues involving electrical, civil, and automation systems to ensure cohesive integration.
• Direct the commissioning phase and performance verification, testing cooling performance under standard, fault, and standby conditions, while closing out any identified deficiencies.
• Manage plumbing and drainage coordination, oversee the final handover process, and ensure the completion of as-built records and operator training sessions.

Requirements

• A bachelor's degree or higher in Mechanical Engineering, HVAC, Refrigeration, Building Services, or a related discipline.
• At least eight years of engineering experience, with a minimum of three years dedicated to data centre cooling systems, including direct involvement in construction, installation, and commissioning.
• Proven hands-on experience implementing liquid-cooled data centres for NVIDIA GB-series platforms (such as GB200 or GB300), covering installation, testing, or project delivery.
• Strong ability to independently interpret technical drawings, equipment specs, and test protocols, with the skill to align liquid cooling hardware with facility cooling systems.
• Demonstrated success in managing relationships with design consultants, contractors, and suppliers; experience on the owner side or within Malaysian/Southeast Asian data centre projects is preferred.
• Full professional proficiency in English, enabling effective technical discussions, meeting participation, and document review.
