Job Description Summary

The Liquid Cooling Lead oversees maintenance, reliability, and lifecycle programs for liquid cooling systems in mission-critical data center environments. This role supports direct-to-chip cooling, rear door heat exchangers, immersion cooling, coolant distribution units, piping, and related infrastructure. As the subject matter expert, the Liquid Cooling Lead ensures maintenance activities preserve thermal redundancy, uptime, fluid integrity, and system performance while partnering with operations, engineering, and vendors to reduce risk and improve cooling efficiency.

Essential Functions & Responsibilities

• Develop, maintain, and continuously improve preventive, predictive, and corrective maintenance programs for liquid cooling systems, including CDUs, piping, immersion systems, and heat exchangers.
• Serve as the technical authority for liquid cooling infrastructure, ensuring thermal redundancy, flow stability, and system resiliency during maintenance and operational activities.
• Develop, review, and approve SOPs, MOPs, and EOPs for liquid cooling operations, maintenance, isolation, balancing, and emergency response.
• Plan and approve maintenance activities and outages involving loop isolation, flow control, system balancing, and post-maintenance verification.
• Establish and manage coolant quality programs, including filtration, contamination control, particulate monitoring, chemical balance, and treatment standards.
• Implement coolant testing protocols for pH, conductivity, dissolved solids, chemical composition, dielectric properties, corrosion inhibitors, biocides, and system compatibility.
• Lead root cause analysis for leaks, contamination events, thermal excursions, flow issues, and system inefficiencies; recommend corrective and preventive actions.
• Ensure fluid handling, storage, replacement, spill prevention, and disposal practices comply with environmental, safety, and OEM requirements.
• Coordinate vendor services for coolant treatment, system flushing, chemical management, testing, and maintenance support.
• Oversee leak detection systems and response protocols to support rapid identification, escalation, and mitigation of coolant-related risks.
• Monitor system performance following maintenance, including flow rates, pressures, temperature differentials, alarms, and operating trends.
• Maintain accurate CMMS records, including asset data, maintenance schedules, service history, and fluid management tasks.
• Support commissioning, recommissioning, capacity planning, and lifecycle planning for high-density compute environments and emerging cooling technologies.
• Identify degradation trends and recommend system upgrades, operational improvements, or fluid replacement strategies.
• Provide technical guidance, training, audit support, inspection support, and client-facing reporting related to cooling and fluid performance.
• Drive continuous improvement initiatives that enhance cooling efficiency, fluid performance, reliability, and operational readiness.

Requirements

• 5-8 years of experience in data center cooling, mechanical systems, facilities operations, or a related mission-critical environment.
• Hands-on experience with liquid cooling technologies such as CDUs, immersion cooling, RDHx, hydronic systems, or high-density cooling infrastructure.
• Strong knowledge of fluid chemistry, filtration, coolant treatment, contamination control, and heat transfer principles.
• Experience developing or managing maintenance programs, CMMS records, SOPs, MOPs, EOPs, and outage planning activities.
• Proven troubleshooting, root cause analysis, and corrective action skills in mechanical or cooling systems.
• Working knowledge of environmental, safety, spill prevention, and fluid handling requirements.
• Ability to support 24/7 operations, including escalations, planned maintenance windows, and emergency response as needed.
• Relevant technical certifications are preferred.
