• Knowledgeable on High-Density Liquid Cooling (HDLC) products utilized in global data center applications
• In depth knowledge of rack manifold manufacturing, design and function (Machining and Welding, Surface Finishing, Material and Surface Treatments, Post-Production Cleaning, Flow Optimization, Thermal Expansion, Connection Interfaces, High-Point Vents and Low-Point Drains)
• Review CAD/Technical Data Packages to determine and validate mechanical design requirements for components and their functions within a system environment
• Responsible for understanding product specifications, plumbing, and hydronic systems to lead reviews with all disciplines ensuring the design and components meet performance and applicable code requirements
• Ability to evaluate thermal data collected from engineering or manufacturing tests to confirm product conformance to thermo-mechanical requirements, testing and modeling
• Knowledgeable in fabrication practices and installation of copper, stainless steel and aluminum piping for large-scale cooling systems
• Understanding and conducting stress and flow analysis to ensure that the piping systems can withstand operational conditions without failure
• Collaborate with project managers on design quotations
• Provide technical input to identify and mitigate project risks that may impact project plans and schedules
• Conduct component selection for pipes, fittings, and valves based on factors like fluid type, temperature, pressure, and corrosion resistance in chillers, HVAC systems and liquid cooling loops
• Collaborate with cross-functional teams to design and ensure system compatibility and integration for liquid cooling systems at the rack, site, equipment, and system levels, including water chillers, heat exchangers, Air Handler Units, and more
• Ability to prepare technical specifications for piping components and systems, including testing procedures, installation procedures and maintenance guidelines
• Utilize CAD tools, CAE tools, and equipment for engineering tasks
• Evaluate/optimize manufacturing assembly processes by designing, modifying, and testing manufacturing methods and equipment, conferring with equipment vendors, and soliciting observations from production team
• Adept at creating detailed mechanical design of components, sub-assemblies, and system integration
• Capable of creating a Bill of Materials (BOM) for release to manufacturing
• Perform tests, debug, and validation of mechanical systems and support manufacturing processes
• Manage relationships with mechanical component vendors and contract manufacturers
• Keep updated with the latest technologies and methods to ensure competitive and cost-effective designs
• Works with your manager to propose potential R&D project ideas to enhance competency areas
• Discuss with management and production staff to assess engineering feasibility and cost-effectiveness
• Apply modular data center design principles to liquid cooling integration standardized, repeatable mechanical packages that can be built, tested, and validated in a factory environment prior to shipment
• Design cooling systems for prefabricated and skid-mounted deployment, accounting for transport and vibration loads, shipping envelope constraints, and inter-module connection interfaces
