[Hiring] Principal Advisor, Liquid Cooling & MEP Systems @World Wide Technology

Role Description

The Principal Advisor, Liquid Cooling & MEP Systems brings deep, hands-on technical expertise in direct-to-chip and rear-door liquid cooling — CDUs, coolant distribution, manifolds, and controls integration — to WWT's AI Factory engagements. This is a technical advisory role, not a self-perform or engineer-of-record role: you review and advise on liquid-cooling architecture, evaluate partner and OEM deliverables for soundness, and size cooling systems against real AI-density heat loads, working in close partnership with the Principal MEP Advisor and the practice's delivery partners. This role is accountable for:

• Reviewing and advising on liquid-cooling architecture — CDUs, coolant distribution, manifolds, and controls — across client and partner MEP designs, flagging risks and gaps before they reach the field.
• Sizing and validating facility water and heat-rejection strategy against rack-level heat load for AI-density deployments.
• Evaluating partner and OEM liquid-cooling deliverables — CDU commissioning, coolant chemistry, flow balancing, leak detection — for technical soundness.

Qualifications

• A minimum of 7 years' progressive experience in mechanical/MEP engineering, with direct hands-on liquid cooling deployment experience.
• Direct, hands-on experience with direct-to-chip and rear-door liquid cooling systems at data center scale — CDUs, coolant distribution, manifolds.
• Experience sizing and validating cooling systems for high-density (60–150 kW/rack and beyond) environments.
• The ability to read, review, and red-line liquid-cooling schematics and designs and be right — not just conversant.
• Bachelor's degree in Mechanical Engineering, Electrical Engineering, or a related field, or equivalent professional experience.

Requirements

• NVIDIA AI Factory / rack-scale platform experience (GB200, GB300, NVL72-class).
• Experience with CFD thermal modeling, power-system studies, and staged capacity analysis.
• DCD Cooling Professional (Uptime Institute), NVIDIA NCA-AIIO, or manufacturer CDU / direct-liquid-cooling training.
• Experience qualifying and overseeing liquid-cooling trade partners and CDU manufacturers.
