Job description
Job Summary
Position Overview
We are seeking a top-tier Subject Matter Expert (SME) – HVAC & Liquid Cooling to serve as the ultimate technical authority on thermal engineering, liquid cooling innovation, and HVAC architecture for our next-generation AI data centers.
You will lead the design standards, fluid dynamics modeling, vendor benchmarking, and technical validation for high-density cooling infrastructure. This role is responsible for ensuring our facilities reliably support 100 kW to 150 kW+ per rack GPU deployments using direct-to-chip, immersion, and advanced hydronic cooling loops.
Key Responsibilities
. Advanced Liquid Cooling Architecture & Innovation
Direct-to-Chip & Immersion Topology: Define the global technical standards for direct-to-liquid cold plate loops, single/two-phase immersion cooling, Coolant Distribution Units (CDUs), and Rear Door Heat Exchangers (RDHx).
Fluid Dynamics & Thermal Modeling: Lead Computational Fluid Dynamics (CFD) modeling, hydronic network calculations, pressure drop analysis, and thermal capacity planning for high-density GPU clusters (e.g., NVIDIA H100/B200/GB200).
Coolant Chemistry & Fluid Management: Establish strict fluid quality guidelines, dielectric/glycol chemical specs, water treatment protocols, filtration standards, and corrosion prevention controls.
2. HVAC & Central Plant Optimization
Primary Heat Rejection Systems: Architect low-PUE primary cooling systems, including magnetic-bearing chillers, adiabatic dry coolers, free-cooling economizers, and cooling towers.
Hybrid Air & Liquid Systems: Design balanced thermal environments where liquid cooling handles 80–90%+ of rack heat load while supplementary CRAH/CRAC units maintain ambient data hall humidity and air distribution.
Energy & Sustainability Optimization: Drive industry-leading Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE) metrics aligned with ASHRAE TC 9.9 liquid cooling guidelines.
3. Peer Review, Troubleshooting & OEM Engagement
Design Validation & Review: Perform deep-dive technical reviews of MEP consultant drawings, single-line hydronic schematics, and equipment specifications across all global projects.
Root-Cause Failure Analysis: Serve as the escalation lead for complex thermal failures, fluid leaks, pressure drops, or CDU performance degradation during testing or live operations.
Vendor Benchmarking & R&D: Evaluate next-gen liquid cooling hardware from global OEMs, pilot emerging cooling technologies, and drive custom equipment engineering with suppliers.
