Full Job Description
JOB SUMMARY

The Liquid Cooling Systems Engineer serves as the internal subject matter expert (SME) for liquid cooling technologies supporting Jabil's manufacturing and deployment of data center hardware, including rack and server platforms.

This role provides technical guidance on cooling system design, process standards, and implementation strategies to support scalable, high-reliability production. You will evaluate emerging cooling technologies, components, and suppliers to enable future product development and drive continuous improvement across manufacturing operations.

Partnering with systems, electrical, and software engineering teams, you will ensure effective integration of liquid cooling solutions into complex hardware systems. Additionally, you will mentor junior engineers and support cross-functional execution to deliver high-performance data center products.

ESSENTIAL DUTIES AND RESPONSIBILITIES
  • Optimize cooling and fluid handling processes to improve efficiency, reliability, safety, and sustainability.
  • Lead the engineering, optimization, and scaling of liquid cooling processes supporting the manufacturing of 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.
  • Develop and maintain detailed engineering process documentation, including P&IDs, schematics, and layouts (pumps, compressors, chillers, CDUs, sensors, valves).
  • Collaborate cross-functionally with systems, electrical, and software teams to ensure seamless integration of cooling into complex server and rack-level architectures.
  • Drive engineering improvements to enhance thermal performance, system reliability, and manufacturing efficiency, while reducing energy consumption and operating costs.
  • Monitor key parameters (pressure, temperature, flow rate, glycol concentration) via BMS.
  • Use data-driven methods to predict failures, optimize system performance, and support preventative maintenance strategies.
  • Develop and manage maintenance plans for process assets.
  • Collaborate with EHS on SOPs for safety, leak mitigation, waste disposal, and fluid handling.
  • Conduct CTQ analyses and risk assessments.
  • Own lifecycle management of cooling subsystems and process equipment, from development through production and deployment.
  • Support commissioning and validation of new systems and upgrades.


JOB QUALIFICATIONS

Required Qualifications:
  • Bachelor's degree in Mechanical or Chemical Engineering, or related field.
  • 10+ years of hands-on engineering experience with liquid cooling, chilled water, or glycol-based systems in product or manufacturing environments.
