About The Position

The Principal Mechanical Design Engineer for Data Center Infrastructure is a technical leader responsible for the architecture, integration, and validation of advanced mechanical systems for hyperscale data centers. The role requires expertise in single-phase and two-phase liquid cooling, hydronic system design, structural integration, and manufacturable rack-level infrastructure. It defines system performance requirements, develops technical specifications, selects and integrates critical components, and leads mechanical design from concept through production release. Work includes wetted-material selection, thermal and structural analysis, fastening strategies, component layout, and design for manufacturability.

The engineer leads end-to-end mechanical design for data center infrastructure such as liquid-cooled rack assemblies, CDUs, manifolds, enclosures, structural frames, and hydronic piping. The role provides technical authority on liquid-cooling architectures, defines and validates operational requirements, and develops and approves specifications and validation plans. It also leads design reviews, vendor qualification, risk mitigation, root-cause investigations, and continuous improvement in manufacturing and assembly. Designs support modular, prefabricated, and skid-mounted deployment, including factory testing, transport loads, shipping constraints, and inter-module connections.

This is a remote role or may be based in Austin, Texas, with up to 25% domestic and/or international travel (described as rare). The listed pay range is $132,400–$238,400. The position is eligible for a performance-based short-term incentive and Jabil benefits.

Requirements

Nice To Haves

• Familiarity with industry standards and regulations related to Energy Storage Systems and Data Center Infrastructure.
• Master’s degree in Mechanical Engineering.
• Professional Engineer (PE) license.
• Hands-on experience designing liquid-cooling systems for modular or prefabricated data center deployments, including factory acceptance testing (FAT) and site integration.

Responsibilities

• Lead end-to-end mechanical design and engineering of hyperscale data center infrastructure, including liquid-cooled rack assemblies, CDUs, manifolds, enclosures, structural frames, and hydronic piping systems.
• Serve as the technical authority for single-phase and two-phase liquid-cooling architectures, including primary and secondary loops, in-rack distribution, and system integration.
• Define and validate performance requirements, 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 stress analysis, finite element analysis, flow modeling, and structural load calculations; ensure mechanical integrity and code compliance.
• Lead wetted-material selection and compatibility analysis, including corrosion mitigation, surface treatments, cleanliness standards, and durability.
• Develop and review CAD models and technical data packages, ensuring design accuracy, manufacturability, and system integration.
• Author and approve technical specifications for piping systems, rack-level cooling infrastructure, and hydronic components, including installation guidelines, maintenance procedures, testing requirements, and applicable standards compliance.
• Establish and oversee validation protocols, including hydrostatic pressure testing, leak detection and mitigation, flow resistance analysis, and corrosion verification.
• Evaluate customer design proposals and technical specifications for feasibility, manufacturability, cost, and risk, and recommend performance and total-cost-of-ownership improvements.
• Lead cross-functional design reviews with electrical, thermal, manufacturing, quality, and supply chain teams to ensure system integration and compliance with product specifications and applicable codes.
• Optimize rack manifold design and manufacturing processes, including machining, welding, surface finishing, connection interfaces, venting and draining, and flow paths.
• Improve manufacturing assembly methods and tooling with production teams and equipment vendors to improve quality, scalability, and cost efficiency.
• Lead root-cause investigations for mechanical failures found 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 affecting performance, schedule, or cost, and contribute to R&D initiatives in liquid-cooling technology and system innovation.
• Apply modular data center design principles to create standardized, repeatable mechanical packages that can be factory-built, tested, and validated before shipment.
• Design cooling systems for prefabricated and skid-mounted deployment, accounting for transport and vibration loads, shipping-envelope constraints, and inter-module connection interfaces.
