Staff Mechanical Engineer - Data Center CoolingNew$349K–$465K

The opportunity

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers.

What you'll do

  • Own cooling-system standards and reference architectures for large-scale AI data centers.

  • Design the complete thermal path from GPU and rack heat capture through: facility distribution and final heat rejection.

  • Translate server, rack, and cluster requirements into coolant temperature,: flow, pressure, water-quality, and facility-capacity requirements.

  • Develop air-cooled, liquid-cooled, and hybrid cooling architectures for: greenfield, retrofit, and partner-operated facilities.

  • Design central plants, technology cooling-water loops, CDUs, heat exchangers,: pumps, piping, chillers, cooling towers, dry coolers, and adiabatic systems.

  • Perform thermal, hydraulic, pressure-drop, heat-transfer, psychrometric, and equipment-capacity calculations.

What they're looking for

  • Evaluate system performance across site climate conditions, compute-load: changes, equipment failures, and maintenance scenarios.
  • Develop and review P&IDs, equipment schedules, layouts, specifications,: sequence of operation, and basis-of-design documents.
  • Define requirements for redundancy, thermal ride-through, failure isolation,: maintainability, efficiency, and water consumption.
  • Establish requirements for coolant chemistry, materials compatibility,: filtration, flushing, cleanliness, leak detection, and fluid management.
