Impact You'll Make

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

You will define system performance requirements, develop technical specifications, select and integrate critical components, and lead mechanical design from concept to production release. Responsibilities include wetted material selection, thermal and structural analysis, fastening strategies, component layout, and design for manufacturability. You will collaborate cross-functionally to deliver reliable, scalable, and cost-effective Data Center Infrastructure solutions while advancing innovation in liquid cooling performance.

Key Responsibilities

• 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.

Minimum Qualifications

• Education: Bachelor's degree in Mechanical Engineering, Systems Engineering, or a related engineering discipline from an accredited university.
• Experience:
  • 8 years of experience in mechanical design and integration of mission-critical systems.
  • Proven track record of successful system designs and implementations in a relevant industry.
  • Strong understanding of mechanical systems, integration strategy, and system coordination.
  • Familiarity with industry standards and regulations related to Energy Storage Systems and Data Center Infrastructure is preferred.
  • Excellent problem-solving skills and attention to detail.
  • Strong communication and teamwork abilities.

Preferred Qualifications

• Master's Degree in Mechanical Engineering
• Professional Engineer (PE) License

Compensation and Benefits

• Pay Range: $132,400 - $238,400 annually. Actual offered rate depends on qualifications, experience, location, education, market data, and internal equity.
• Incentive: Eligible for a short-term performance-based incentive.
• Benefits: Medical, dental, and vision insurance; paid time off (3.07 hours per pay period in the first year); 4 weeks paid parental leave; 11 company-paid holidays in 2026 (9 fixed, 2 floating); 401(k) retirement plan; employee stock purchase plan.
