This role is for a highly innovative and hands-on engineer with the ability and drive to design, analyze, and qualify the mechanical and thermal systems that power AWS's next-generation network hardware. You will own the mechanical and thermal design of network devices and racks, from identifying requirements and simulation to building prototypes and driving designs into volume production. This is a hands-on role that requires a self-starter with deep expertise in thermal management and mechanical analysis, and the ability to drive multiple design iterations while diligently converging on the simplest, most reliable, and most cost-effective solution that satisfies the requirements.
As a Sr. Mechanical/Thermal Engineer within the Network Product Development (NPD) team, you will directly shape how AWS's network infrastructure is built and cooled - at switch, module, and rack level.
Key job 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 - balancing performance, cost, and manufacturability.
- 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 - static, dynamic, thermal stress, vibration, shock) 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.
BASIC QUALIFICATIONS
- Bachelor's degree in mechanical engineering or equivalent
- 5+ years of 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.
PREFERRED QUALIFICATIONS
- Experience working with interdisciplinary teams to execute product design from concept to production
- Knowledge of mechanical systems in critical Data Center operations including but not limited to CRAC/CRAHs/AHUs, chillers, cooling towers, storage tanks, chemical systems, heat exchangers, piping systems, pumps, valves, duct systems, fans, or dampers
- Experience with high-power electronics cooling (network switches, servers, or similar platforms with 1000W+ components) using air and liquid cooling
- Expertise in debugging and troubleshooting mechanical and thermal issues in deployed hardware.
