Liquid Cooling Systems Engineer

About the role

Jabil is looking for a Liquid Cooling Systems Engineer to act as the internal subject matter expert for liquid cooling technologies used in the manufacturing and deployment of data center hardware, including rack and server platforms. The engineer guides cooling system design, process standards and implementation, evaluates emerging technologies, components and suppliers, partners with systems, electrical and software teams, and mentors junior engineers.

Key responsibilities

• Optimize cooling and fluid handling processes for efficiency, reliability, safety and sustainability.
• Lead the engineering, optimization and scaling of liquid cooling processes for data center rack and server solutions.
• Identify and resolve bottlenecks in production and cooling workflows.
• Design, configure and monitor process performance during manufacturing and operations.
• Maintain engineering documentation such as P&IDs, schematics and layouts for pumps, compressors, chillers, CDUs, sensors and valves.
• Drive improvements in thermal performance, reliability and efficiency while reducing energy use and operating costs.
• Monitor pressure, temperature, flow rate and glycol concentration via BMS, predict failures and support preventative maintenance.
• Develop and manage maintenance plans for process assets and work with EHS on safety, leak mitigation and waste disposal procedures.
• Conduct CTQ analyses and risk assessments, and own the lifecycle of cooling subsystems from development through deployment.
• Support commissioning and validation of new systems and upgrades.

Required profile

• Bachelor's degree in Mechanical or Chemical Engineering or a related field.
• 10+ years of hands-on engineering experience with liquid cooling, chilled water or glycol-based systems in product or manufacturing environments.
• Experience with data center hardware, server platforms or high-density compute systems, or similar complex, high-reliability systems (e.g., pharma, food and beverage, distillery).
• Strong analytical and problem-solving skills, and the ability to drive cross-functional change with data.

Required skills

• Thermodynamics, fluid mechanics and heat transfer.
• Process control systems, instrumentation and sensors.
• DMAIC, root cause analysis and continuous improvement.
• Familiarity with ISO 9001 and regulatory compliance affecting process control.
• Preferred: data center liquid cooling (immersion or direct-to-chip), OCP and ASHRAE standards, BMS and SCADA, Six Sigma or Lean certification, and CFD or thermal simulation tools.
