Sr. Principal Mechanical Integration Engineer – Data Center Liquid Cooling (REMOTE)

Jabil • Austin, TX

2d • $164,200 - $295,600 • Remote

About The Position

The Senior Principal Mechanical Design Engineer will lead mechanical integration for data center infrastructure, with a focus on liquid cooling systems. The role requires a strong understanding of thermal-component manufacturing processes and thermal design and analysis. Responsibilities include developing specifications, selecting and placing components, choosing fastening methods, and transitioning designs into manufacturing. The engineer will also lead test-process implementation and equipment selection to support operational excellence and reliability.

The position serves as a subject matter expert in single-phase and two-phase liquid cooling for hyperscale data centers, including primary, in-rack, enclosed, and facility-based cooling solutions. It covers cooling distribution units, high-density liquid cooling products, rack manifolds, piping systems, and integration with equipment such as chillers, heat exchangers, and air handler units. The engineer will design for modular, prefabricated, and skid-mounted deployments, considering factory validation, transport and vibration loads, shipping constraints, and field connection interfaces.

The role is remote or based in Austin, Texas, and may require domestic and/or international travel, generally described as 20%–30% and elsewhere as up to 30%.

Requirements

• Bachelor’s degree in Mechanical Engineering, Systems Engineering, or a related field; a suitable combination of education, experience, and/or training may be considered.
• At least 8 years of experience in mechanical system integration.
• Track record of successful system designs and implementations in a relevant industry.
• Strong understanding of mechanical systems, integration strategy, and system coordination.
• Strong background in liquid-cooling technology used in data center design and buildout.
• Knowledge of enclosed and facility-based cooling systems, current cooling distribution unit technologies, and high-density liquid-cooling products.
• In-depth knowledge of rack-manifold manufacturing, design, and function.
• Knowledge of plumbing, hydronic systems, piping fabrication and installation, and component selection for cooling systems.
• Ability to interpret and validate CAD and technical data packages and evaluate thermal test data.
• Ability to conduct or assess stress and flow analysis and testing for leaks, hydrostatic pressure, flow resistance, and corrosion.
• Excellent problem-solving skills and attention to detail.
• Excellent interpersonal, communication, teamwork, writing, presentation, and information-analysis skills.
• Creative, self-motivated, accountable, and team-oriented, with the ability to work independently with minimal oversight.
• Ability to communicate effectively with management, clients, production staff, and global teams; influence others and share best practices.
• Ability to assess projects, articulate risks, develop project milestones, and work with stage-gate processes in project lifecycle management.
• Ability to mentor junior engineers.
• Ability to travel 20%–30% as required.

Nice To Haves

• Master’s degree in Mechanical Engineering, Systems Engineering, or a related engineering discipline.
• Active Professional Engineer (PE) license.
• Familiarity with industry standards and regulations related to data center infrastructure.
• Hands-on experience designing liquid-cooling systems for modular or prefabricated data center deployments, including factory acceptance testing (FAT) and site integration.
• Familiarity with modular data center product architectures and constraints related to factory build, transport, and field commissioning.

Responsibilities

• Serve as a subject matter expert on single-phase and two-phase liquid cooling applications in hyperscale data centers, including primary and in-rack cooling solutions.
• Develop and review mechanical requirements and specifications for liquid-cooling systems, components, and infrastructure.
• Select and place components, including pipes, fittings, and valves, based on fluid type, temperature, pressure, and corrosion resistance.
• Define operational expectations for liquid-cooling racks, manifolds, and infrastructure, including pressure ratings, temperature ranges, flow uniformity, and durability.
• Review CAD and technical data packages to validate component mechanical design requirements and functions within the system.
• Lead cross-discipline design reviews to ensure plumbing, hydronic systems, components, performance, and applicable code requirements are addressed.
• Evaluate thermal data from engineering and manufacturing tests to confirm conformity with thermo-mechanical requirements, testing, and modeling.
• Assess and conduct stress, flow, leak-mitigation, hydrostatic-pressure, flow-resistance, and corrosion testing or analysis.
• Apply relevant international standards, including ASME and ISO, to testing and validation.
• Design and evaluate rack manifolds, including machining and welding, surface finishing and treatments, cleaning, flow optimization, thermal expansion, connection interfaces, vents, and drains.
• Support fabrication and installation of copper, stainless-steel, and aluminum piping for large-scale cooling systems.
• Integrate liquid-cooling systems across rack, site, equipment, and system levels, including chillers, heat exchangers, air handler units, and related equipment.
• Prepare technical specifications for piping components and systems, including testing, installation, and maintenance procedures.
• Use CAD and CAE tools and engineering equipment to complete design and analysis tasks.
• Optimize manufacturing assembly processes by designing, modifying, and testing methods and equipment, working with equipment vendors, and gathering production-team observations.
• Create detailed mechanical designs for components, subassemblies, and system integration, and prepare bills of materials for manufacturing release.
• Perform testing, debugging, and validation of mechanical systems and support manufacturing processes.
• Manage relationships with mechanical-component vendors and contract manufacturers.
• Collaborate with project managers on design quotations and provide technical input to identify and mitigate risks that could affect plans and schedules.
• Discuss engineering feasibility and cost-effectiveness with management and production staff.
• Apply modular data center design principles to create standardized, repeatable mechanical packages that can be built, tested, and validated in a factory before shipment.
• Design cooling systems for prefabricated and skid-mounted deployment, accounting for transport and vibration loads, shipping-envelope constraints, and inter-module connections.
• Keep current with technologies and methods to support competitive, cost-effective designs, and propose potential R&D projects with the manager.
• Assess projects, articulate risks, develop milestones, participate in stage-gate project lifecycle processes, and mentor junior engineers.
