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.
You
Have experience designing cooling systems for data centers, mission-critical facilities, central plants, or large industrial environments.
