Job summary

Lambda, The Superintelligence Cloud, is seeking a mechanical engineer to design cooling systems for large-scale AI data centers. You will own cooling-path design, select equipment, and develop layouts to meet reliability and efficiency targets.

You'll collaborate across engineering, construction, and operations, travel to sites as needed, and help establish standards for redundancy and water management. Bachelor's in ME required.

Qualifications

• Design cooling systems for data centers, mission-critical facilities, central plants, or large industrial environments.
• Understand hydronic design, heat transfer, pumping, heat exchangers, chilled-water systems, and heat-rejection equipment.
• Have experience with direct-to-chip liquid cooling, CDUs, technology cooling-water loops, or other high-density cooling systems.
• Can develop and review P&IDs, equipment specifications, mechanical layouts, and engineering calculations.
• Can model system capacity, flow, pressure loss, temperature approach, and performance across varying operating conditions.

Responsibilities

• 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.
• 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.
• Review partner designs, vendor submittals, equipment selections, and construction documents for compliance with Lambda standards.
• Coordinate cooling interfaces across hardware engineering, electrical engineering, controls, construction, commissioning, and operations.
• Support equipment testing, construction sequencing, commissioning, cooling-system bring-up, and initial GPU loading.
• Investigate thermal events and cooling failures, incorporating lessons into future designs and operating standards.
• Travel to project sites, manufacturers, and partner facilities as needed.
