Staff Mechanical Engineer — Hybrid Data-Center Cooling Lead

Lambda; United States; Remote; USD 130,000 - 200,000; Full time

Job summary

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure, seeking a Mechanical Engineer to own design standards and cooling architectures for large-scale data centers. The role requires in-person presence in San Francisco or San Jose four days per week, with Tuesday as the work-from-home day.

You will develop central plants, cooling systems, and equipment specs, perform detailed calculations, and review partner designs to ensure Lambda standards and reliability across projects.

Qualifications

• Bachelor's degree in mechanical engineering or equivalent.
• Experience designing mechanical systems for data centers or mission-critical facilities.
• Ability to develop and review P&IDs, mechanical layouts, equipment schedules, specifications, and calculations.
• Knowledge of hydronic, chilled-water, heat transfer, and water-treatment systems.
• Familiarity with relevant codes and standards.

Responsibilities

• Own mechanical design standards and reference architectures for large-scale AI data centers.
• Develop cooling architectures for greenfield, retrofit, and partner-operated facilities.
• Design central plants, heat-rejection systems, hydronic distribution, air-cooling systems, and direct-to-chip liquid-cooling infrastructure.
• Perform cooling-load, heat-transfer, hydraulic, pressure-drop, psychrometric, and equipment-capacity calculations.
• Develop and review P&IDs, equipment schedules, layouts, specifications, sequences of operation, and basis-of-design documents.
• Select and size chillers, cooling towers, dry coolers, pumps, heat exchangers, CRAHs, CDUs, piping, valves, and water-treatment systems.
• Evaluate designs for capacity, redundancy, failure isolation, maintainability, efficiency, water use, constructability, cost, and schedule.
• Translate GPU, rack, and cluster thermal requirements into facility cooling requirements.
• Review partner designs, vendor submittals, construction documents, and equipment packages for compliance with Lambda standards.
• Coordinate mechanical interfaces with electrical systems, controls, building structure, hardware engineering, construction, commissioning, and operations.
• Travel to project sites, manufacturers, and partner facilities as needed.
