Use CFD tools (FloTherm or Macroflow) to perform switch, rack, and system-level thermal/fluid analysis (flow distribution, pressure drop, and temperature profiling)
Design and optimize thermal components using 3D CAD (Creo or SolidWorks) to support seamless hardware integration and testing
Participate in customer engagements and site visits to understand and document deployment constraints and gather feedback for design improvements
Partner with factory teams to ensure racks are built with proper airflow, hose routing, and thermal safeguards, while establishing best practices that improve build consistency across deployments
Collaborate with Architects/Compliance/Reliability and global vendors to align thermal architectures with total system design and international data center/thermal/mechanical standards (e.g., UL, OCP, ASHRAE, ISTA, ASTM, NEBS)
Conduct thermal, mechanical, and reliability testing, analyzing airflow, coolant flow rates, pressure drops, and structural integrity to ensure compliance with the end-users’ specifications
Develop and maintain design documentation including BOMs, wetted materials compliance, test plans, and engineering change orders (ECOs)
Manage relationships with mechanical/thermal component vendors to build out a robust partner ecosystem consisting of racks, CDUs, hoses, manifolds, QDs, and cold plates
Ensure mechanical designs support airflow management, thermal containment, and integration with cooling systems (e.g., in-row cooling, in-rack cooling, rear door heat exchangers)
Conduct root cause analysis and corrective actions for mechanical and thermal failures or field issues
