Amphenol High Speed Products Group | High Speed IO Connectors

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.

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.
Prior cold plate, liquid cooling, or thermal engineering experience is not required. You will work alongside dedicated thermal and thermal-mechanical engineers who provide analysis, technical guidance, mentoring, and hands‑on collaboration to help you build expertise in these areas. You bring strong mechanical design fundamentals, practical problem‑solving skills, and a demonstrated ability to deliver products.

* This is an experienced engineering role, not an entry‑level position. *

• 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.

• 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 analysis or 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 clear technical documentation and communicate progress, tradeoffs, and issues promptly.

• Serve as a mechanical technical…
