Job Description

We are looking for an experienced Data Center Liquid Cooling Engineer to support the design, integration, implementation, and optimization of liquid-cooling solutions for modern data center infrastructure.

The role focuses on liquid cooling distribution systems, Coolant Distribution Units (CDUs), liquid-cooled server racks, manifolds, quick-connect hoses, and secondary-side piping systems. The ideal candidate will have knowledge of thermal management, cooling infrastructure, fluid distribution, and the operational requirements of high-density computing environments.

Key Responsibilities

Design and support liquid-cooling solutions for data center infrastructure.
Work with cabinet-mounted and rack-mounted Coolant Distribution Units (CDUs).
Support the integration of liquid-cooled server racks and cooling distribution systems.
Design, install, and maintain manifolds, quick-connect hoses, and secondary-side piping assemblies.
Coordinate the integration of liquid-cooling equipment with server racks and data center infrastructure.
Monitor cooling performance, coolant distribution, system pressure, flow, and temperature.
Support system commissioning, testing, troubleshooting, and performance optimization.
Ensure reliable coolant circulation and effective thermal management for high-density computing equipment.
Identify opportunities to improve cooling efficiency, reliability, maintainability, and system performance.
Collaborate with mechanical, electrical, infrastructure, and engineering teams to deliver integrated cooling solutions.
Support preventive maintenance, technical documentation, and continuous improvement activities.
Travel across Southeast Asia to support project implementation, installation, commissioning, troubleshooting, and on-site technical coordination.

Mandatory Requirements

Experience with data center cooling systems or industrial cooling infrastructure.
Knowledge of liquid-cooling technologies and thermal management principles.
Understanding of coolant distribution systems, piping, manifolds, and fluid connections.
Familiarity with pumps, valves, hoses, and cooling-system components.
Ability to interpret technical drawings, system layouts, and equipment specifications.
Experience with installation, testing, commissioning, troubleshooting, or maintenance of cooling systems.
Strong analytical and problem-solving skills.
Good communication and cross-functional collaboration skills.
Willingness and ability to undertake mandatory international travel across Southeast Asia.

Preferred Qualifications

Experience with liquid cooling for high-performance computing (HPC), AI infrastructure, or high-density server environments.
Experience with cabinet-mounted or rack-mounted CDUs.
Knowledge of liquid-cooled server racks and integrated cooling modules.
Experience with secondary-side cooling distribution and prefabricated piping assemblies.
Familiarity with quick-connect couplings and leak prevention in liquid-cooling systems.
Understanding of cooling-system monitoring, pressure management, flow control, and temperature regulation.
Experience optimizing energy efficiency and cooling-system reliability in data centers.

Ideal Candidate Profile

The ideal candidate combines practical engineering knowledge with experience in liquid-cooling systems and data center infrastructure. They should understand how cooling distribution equipment, server racks, piping, and monitoring systems work together to maintain stable operating conditions for high-density computing environments.

Candidates with hands-on experience in CDU integration, liquid-cooling commissioning, thermal management, and troubleshooting will be particularly suitable. The candidate must also be comfortable with mandatory international travel across Southeast Asia to support project activities and on-site technical requirements.
