We also believe in giving back to our communities and fostering a fun and engaging work environment through employee events and social activities.

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.

• 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.
