Amphenol High Speed Products Group | High Speed IO Connectors Position: Product Development Engineer - Mechanical Design for Liquid Cooling Location: Schaumburg, IL Amphenol High Speed Products Group develops high-speed, high-bandwidth interconnect solutions for telecom and datacom markets, including servers, storage, routers, and switches. Our products enable the electronics revolution and support major Tier 1 OEMs globally. We are seeking an experienced Product Development / Mechanical Design Engineer to help develop liquid cooling solutions for next-generation AI/ML and data center platforms. Position Overview This role is for a proven Mechanical Design Engineer who can take ownership of complex components and assemblies from concept through qualification and production. You will develop cold plates, integrated cage and cooling assemblies, and related mechanical solutions, balancing performance, reliability, manufacturability, cost, and customer requirements. This is an experienced engineering role, not an entry-level position.



Key Responsibilities Design and Innovation Lead concept generation and detailed mechanical design of liquid cooling components and assemblies for high-speed I/O and AI infrastructure applications. Create 3D CAD models, engineering drawings, GD&T, tolerance analyses, and bills of materials for precision components and assemblies. Develop robust designs addressing fit, flatness, structural stiffness, contact force, sealing, assembly, and serviceability. Partner with thermal and thermal-mechanical engineers to translate thermal and fluid-performance requirements into practical mechanical designs. Work with manufacturing and suppliers to select materials and processes, improve manufacturability, and resolve design and assembly challenges. Testing and Validation Develop mechanical and reliability validation plans with thermal, quality, and laboratory teams, including dimensional, structural, leak, pressure, and environmental testing as applicable. Perform design FMEA, tolerance analysis, DFM/DFA, and risk assessments; use structural analysisor collaborate with specialists as needed. Support prototype builds, investigate failures, and drive corrective actions using test data and root-cause analysis. Project Management Own development activities from concept through qualification, new product introduction, and production release. Manage project schedules, design deliverables, risks, and engineering changes across global engineering, manufacturing, quality, and supplier teams. Maintain explicit technical documentation and communicate progress, tradeoffs, and issues promptly. Customer Engagement Serve as a mechanical technical interface for customers,



supported by thermal specialists for thermal and fluid-performance discussions. Translate customer requirements into design goals and present concepts, design tradeoffs, validation results, and corrective actions. Incorporate customer feedback throughout design reviews, prototyping, and qualification. Qualifications Bachelor's degree in Mechanical Engineering or a related engineering discipline; a master's degree is a plus. 5+ years of hands-on mechanical design and product development industry experience , with demonstrated ownership of products from concept through production. Strong proficiency in 3D CAD, such as Creo or SolidWorks, and production drawing development. Solid understanding of GD&T, tolerance stack-ups, material selection, mechanical behavior, and design for manufacturing and assembly. Practical experience with precision components and assemblies using processes such as machining, stamping, molding, casting, joining, or mechanical assembly. Demonstrated ability to troubleshoot hardware, lead prototype builds, interpret test results, and resolve design or manufacturing issues. Strong communication skills and the ability to work effectively with customers, suppliers, and global teams while managing multiple projects. Additional Experience That Is Helpful but Not Required Experience with cold plates, liquid cooling, thermal management, fluid systems, sealing, brazing, welding, or leak testing. Experience with structural FEA, such as ANSYS, electronics packaging, or high-speed connector and cage assemblies. Candidates from other mechanical product development industries are encouraged to apply. Direct connector, cold plate, or thermal experience is not a prerequisite; our thermal and thermal-mechanical teams will support your development in liquid cooling technologies. Why Work for Us? Benefits Coverage : Comprehensive health, dental, vision, and travel insurance. Health Care Spending
