Data Center Water Treatment Engineer - Liquid Cooling

Overview

JOB TITLE: Senior Liquid to Chip Technician

REPORTS TO: Chief Engineer

The Senior L2C Technician is a specialist role focused on the installation, maintenance, and integrity of Direct-to-Chip (DTC) liquid cooling systems, ensuring that high-density computing clusters receive continuous, leak-free thermal management.

• Operate and maintain Coolant Distribution Units (CDUs), secondary filtration systems, and manifold delivery networks to ensure precise flow and pressure to the IT racks.
• Perform rigorous hydrostatic pressure testing and vacuum checks on wetted joints and hoses; execute immediate containment protocols in the event of a fluid anomaly.
• Conduct regular sampling of specialized dielectric or treated water fluids; manage “flush and fill” operations to prevent bio-fouling or corrosion within the systems.
• Facilitate the connection of server-level cold plates to the facility-level manifold using dripless Quick Disconnects (QDs) and precision hose routing.
• Monitor flow rates and “Approach Temperatures” via the BMS/EPMS, identifying thermal degradation before it triggers a server throttle or shutdown.

• High school diploma or equivalent required. Technical certifications in Hydraulics, Advanced Plumbing, or HVAC are highly preferred.
• 5+ years of experience with high-precision fluid systems, ideally in Semiconductor FABs, Clean Rooms, or Power Plants.
• Experience with Ultra-Pure Water (UPW) or chemical delivery systems.
• Ability to read and interpret P&IDs (Piping and Instrumentation Diagrams) and understand the physics of heat transfer and fluid dynamics.
• High level of manual dexterity required for working with small-diameter fittings and sensitive electronic components.
• Strong analytical, troubleshooting, and problem-solving skills.
