Responsibilities
Develop and maintain the mechanical POR for Giga Data Centers, defining the "Gold Standard" design that enables manufacturing of reliability and efficiency at scale
Author and own the internal engineering library including technical specifications and Basis of Design documents, deciding what we build and how we measure it
Design to global and local standards, leveraging ASHRAE TC 9.9 to define environmental envelopes for AI hardware and ensuring compliance with ASHRAE 90.1 for energy efficiency
Guide external engineering firms to localize designs while maintaining strict adherence to core performance intent and standardization requirements
Validate airflow patterns and rack-level thermal performance using computational fluid dynamics, ensuring compliance with ASHRAE thermal guidelines for Class A1-A4 environments
Execute rigorous hydraulic analysis and thermal load flow studies, conducting pipe stress analysis per ASME B31 standards to ensure system integrity under thermal expansion and seismic events
Engineer complex cooling loops (Direct-to-Chip, Immersion, RDHx) aligned with OCP (Open Compute Project) specifications for liquid cooling interoperability
Select and specify pumps, fans, chillers, dry coolers, and control valves for high-density compute environments
Create detailed Bills of Material (BOMs), Quantity Take Offs (QTOs), and Commissioning scripts to support a manufacturing-first supply chain
Develop Sequence of Operations (SOO) and Control Narratives that dictate how mechanical systems respond to dynamic AI load changes
Use advanced simulation tools to optimize thermal performance and validate designs before manufacturing
