How will you make an impact

The Principal Mechanical Design Engineer (Data Center Infrastructure) is a technical leader responsible for the architecture integration and validation of advanced mechanical systems supporting hyperscale data center environments. This role requires deep expertise in liquid cooling technologies (single-phase and two-phase) hydronic system design structural integration and manufacturable rack-level infrastructure solutions.

This role is responsible for defining system performance requirements developing technical specifications selection and integration of critical components and leading mechanical design from concept through production release. Responsibilities include wetted material selection thermal and structural analysis fastening strategies component layout and design for manufacturability. Partners cross-functionally to deliver reliable scalable and cost-effective Data Center Infrastructure solutions while advancing innovation in liquid cooling performance.

What will you do

• Lead the end-to-end mechanical design and engineering of hyperscale Data Center Infrastructure (DCI) systems including liquid-cooled rack assemblies CDUs manifolds enclosures structural frames and associated hydronic piping systems.

• Serve as the technical authority for single-phase and two-phase liquid cooling architectures including primary and secondary loop design in-rack distribution and system integration within hyperscale data center environments.

• Define and validate operational performance requirements for liquid-cooled infrastructure including pressure ratings hydrostatic limits temperature ranges flow rates and uniformity thermal expansion durability and serviceability.

• Design analyze and validate machined components welded fabrications manifolds and structural systems using advanced engineering principles including stress analysis finite element analysis (FEA) flow modeling and structural load calculations to ensure mechanical integrity and code compliance.

• Lead wetted material selection and compatibility analysis for liquid cooling systems including corrosion mitigation strategies surface treatments cleanliness standards and long-term durability considerations.

• Develop and review CAD models and complete technical data packages using CREO SolidWorks or equivalent tools; ensure design accuracy manufacturability and system-level integration.

• Author and approve technical specifications for piping systems rack-level cooling infrastructure and hydronic components including installation guidelines maintenance procedures testing requirements and compliance with applicable standards (ASME ISO).

• Establish and oversee validation protocols including hydrostatic pressure testing leak detection and mitigation flow resistance analysis and corrosion verification to ensure regulatory compliance and operational reliability.

• Evaluate customer design proposals and technical specifications to assess feasibility manufacturability cost and risk; provide recommendations to optimize performance and total cost of ownership.

• Lead cross-functional design reviews with electrical thermal manufacturing quality and supply chain teams to ensure full system integration and compliance with product specifications and applicable plumbing and hydronic codes.

• Optimize rack manifold design and manufacturing processes including machining welding surface finishing connection interfaces venting and draining strategies and flow path optimization to enhance performance and manufacturability.

• Drive continuous improvement in manufacturing assembly methods and tooling in collaboration with production teams and equipment vendors to improve quality scalability and cost efficiency.

• Lead root cause investigations for complex mechanical failures identified during validation or field deployment and implement corrective design improvements.

• Provide technical leadership in vendor qualification and management for mechanical components and liquid cooling subsystems.

• Identify and mitigate technical risks impacting performance schedule or cost and contribute to R&D initiatives advancing liquid cooling technologies and system innovation.
