Role Overview

We are seeking an experienced CDU (Coolant Distribution Unit) / Liquid Cooling Data Center Site Lead to oversee onsite operations supporting high-density compute and direct-to-chip liquid-cooled data center infrastructure in Manassas, VA.

This role will provide technical leadership to Data Center Technicians responsible for the deployment, operation, maintenance, troubleshooting, and support of CDU systems and liquid-cooled GPU/compute infrastructure. The Site Lead will serve as the primary onsite technical escalation point for CDU-related incidents, cooling loop performance, coolant flow and pressure abnormalities, leak detection, and associated infrastructure issues.

The ideal candidate will possess hands-on experience with Coolant Distribution Units, direct-to-chip liquid cooling systems, high-density rack infrastructure, and mission-critical data center operations. This individual must be capable of leading technicians, coordinating with facilities and engineering teams, and maintaining operational reliability within a 24x7 data center environment.

Key Responsibilities

• Lead daily onsite operations focused on CDU systems, direct-to-chip liquid cooling infrastructure, and high-density compute environments.
• Provide technical direction, oversight, and mentorship to Data Center Technicians supporting liquid-cooled infrastructure.
• Oversee the installation, deployment, commissioning support, maintenance, troubleshooting, and operational readiness of Coolant Distribution Units.
• Support direct-to-chip liquid cooling infrastructure, including CDUs, cooling distribution loops, manifolds, coolant hoses, quick disconnects, and associated monitoring systems.
• Monitor and troubleshoot CDU operational parameters, including coolant flow rates, pressure, supply and return temperatures, alarms, and system performance.
• Investigate and coordinate response to coolant leaks, flow restrictions, pressure fluctuations, temperature abnormalities, and CDU-related operational incidents.
• Support high-density GPU servers, compute racks, networking infrastructure, rack integration, structured cabling, and hardware deployment activities.
• Lead incident response, technical troubleshooting, root-cause analysis, and escalation of critical cooling and infrastructure issues.
• Coordinate with data center facilities, mechanical engineering, hardware engineering, networking, remote operations, and vendor support teams.
• Manage technician work assignments, shift priorities, ticket queues, maintenance schedules, and operational handoffs.
• Ensure adherence to established SOPs, MOPs, EOPs, change-control procedures, maintenance standards, and operational documentation.
• Maintain accurate records of CDU performance, maintenance activities, incidents, asset inventories, and infrastructure changes.
• Enforce safety standards and operational procedures when working with liquid cooling systems, electrical infrastructure, mechanical equipment, and high-density compute environments.

Required Qualifications

• 5+ years of experience in data center operations, critical infrastructure, or mission-critical technical environments.
• Previous experience leading Data Center Technicians, onsite operations teams, or technical infrastructure support activities.
• Hands-on experience supporting Coolant Distribution Units (CDUs) and liquid-cooled data center infrastructure.
• Working knowledge of direct-to-chip liquid cooling, cooling loops, manifolds, coolant distribution, quick disconnects, leak detection, and flow/pressure monitoring.
• Experience troubleshooting CDU alarms, cooling performance issues, coolant flow abnormalities, temperature fluctuations, and liquid cooling system incidents.
• Strong understanding of high-density compute infrastructure, GPU servers, rack integration, structured cabling, networking, and power distribution.
• Experience supporting data center operational processes, incident management, change control, maintenance procedures, and technical documentation.
• Ability to coordinate technical escalations across facilities, engineering, operations, and vendor teams.
• Strong leadership, communication, troubleshooting, and organizational skills.
• Ability to work onsite in Manassas, VA, and transition to the assigned graveyard shift following the initial 30-day onboarding period.

Preferred Qualifications

• Experience supporting NVIDIA GPU infrastructure or other high-density AI/ML compute platforms.
• Experience in direct-to-chip liquid-cooled data centers supporting AI, HPC, or high-density GPU clusters.
• Previous hands-on experience with CDU commissioning, startup, maintenance, or performance monitoring.
• Familiarity with liquid cooling OEM equipment, CDU telemetry, DCIM platforms, and infrastructure monitoring tools.
• Experience working in large-scale hyperscale or enterprise data center environments.
