Senior Thermal & Mechanical Engineer – Data Center Hardware

Socket.dev; Seattle (WA); On-site; USD 159,000 - 215,000; Full time

Job summary

Amazon is seeking a Sr. Mechanical/Thermal Engineer to own the mechanical and thermal design of network devices and racks for AWS Infrastructure Services. You will perform CAD modeling, thermal simulations, and validation across switch, module, and rack levels.

Collaborate with electrical, firmware, manufacturing, and supply chain teams; develop test plans, qualification methods, and design packages; drive root-cause analysis and continuous improvement. On-site in Seattle, WA.

Qualifications

• Bachelor's degree in mechanical engineering or equivalent.
• 5+ years hardware design and validation of components, subsystems and systems experience.
• Experience in 3D CAD
• 2+ years of experience working with ODM/JDM/CM suppliers in a product development environment.

Responsibilities

• Identify and analyze thermal and mechanical requirements for network platforms and rack assemblies through collaboration with cross-functional disciplines (electrical, firmware, manufacturing, supply chain).
• Conceive and develop trade studies on thermal solutions including heatsink geometries, fan curves, airflow paths, liquid cooling, and TIM selections.
• Create and iterate detailed 3D CAD models of mechanical and thermal designs — enclosures, sheet metal, heatsinks, fan assemblies, cable management, and rack mounting.
• Perform thermal simulations (CFD) and mechanical analyses (classical and FEA) for all load conditions and compliance.
• Develop test plans throughout development with variable isolation DOEs and statistical analysis for long-term reliability assessments.
• Define qualification plans and identify acceptance testing methods appropriate for volume production.
• Produce complete design packages — detailed drawings, analysis reports, BOMs, and assembly documentation.
• Drive root cause analysis on field failures and work with operations to improve quality processes.
