Staff Mechanical Engineer (Data Center Cooling)

Join our team as a Staff Mechanical Engineer specializing in data center cooling. In this role, you will own cooling-system standards and reference architectures for large-scale AI data centers. You will design the complete thermal path from GPU and rack heat capture through facility distribution and final heat rejection.

Additionally, you will perform various calculations, evaluate system performance, and coordinate cooling interfaces across multiple engineering disciplines.

Responsibilities

• You will also develop air-cooled, liquid-cooled, and hybrid cooling architectures for various facility types.
• Travel to project sites and partner facilities may be required.
• Posséder des normes et des architectures de référence pour les systèmes de refroidissement des centres de données à grande échelle.
• Concevoir le chemin thermique complet depuis la capture de chaleur jusqu'à l'évacuation finale de la chaleur.
• Développer des architectures de refroidissement pour des installations neuves, des rénovations et des installations exploitées par des partenaires.
• Communicate clearly across engineering, construction, operations, equipment vendors, and executive stakeholders
• Understand hydronic design, heat transfer, pumping, heat exchangers, chilled-water systems, and heat-rejection equipment
• Can develop and review P&IDs, equipment specifications, mechanical layouts, and engineering calculations
• Understand cooling-system redundancy, failure domains, thermal ride-through, maintainability, and operational risk
• Can model system capacity, flow, pressure loss, temperature approach, and performance across varying operating conditions
• Can balance reliability, efficiency, water consumption, equipment cost, and delivery schedule
• Experience with warm-water cooling, water-side economization, dry coolers, or adiabatic heat rejection

Requirements

• Hold a bachelor’s degree in mechanical engineering or equivalent practical experience
• Have experience designing cooling systems for data centers, mission-critical facilities, central plants, or large industrial environments
• Understand the relationship between GPU behavior, rack density, coolant conditions, and facility cooling capacity
• Have experience with direct-to-chip liquid cooling, CDUs, technology cooling-water loops, or other high-density cooling systems
• Familiarity with ASHRAE TC 9.9 guidance and liquid-cooling industry standards
• Experience designing cooling for hyperscale, colocation, HPC, or AI data centers
• Experience supporting multi-megawatt liquid-cooled GPU deployments
• Familiarity with CFD, Pipe-Flo, AFT Fathom, Revit, or comparable engineering tools
• Professional Engineer licensure or progress toward licensure

Preferred

• Knowledge of coolant chemistry, glycol systems, corrosion control, filtration, and wetted-material compatibility
• Experience with factory testing, commissioning, integrated systems testing, or live system bring-up
