JOB TITLE: Critical Facilities Engineer - Direct-to-Chip Liquid Cooling
REPORTS TO: Chief Engineer
YOUR ROLE:The Critical Facilities Engineer - Direct-to-Chip Liquid Cooling is responsible for the operation, maintenance, testing, and reliability of advanced liquid cooling infrastructure supporting high-density compute environments. This role specializes in CDU operations, manifold distribution systems, coolant integrity, thermal performance monitoring, and leak prevention across mission-critical AI and HPC deployments.
This is a mechanical and critical infrastructure engineering role and is not an IT support or server repair position.
RESPONSIBILITIES:- 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.
QUALIFICATIONS:- 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.
