Senior MechanicalThermal Engineer, Network Product Development (NPD)

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 AWSs 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.

AWS Infrastructure Services owns the design planning delivery and operation of all AWS global other words were the people who keep the cloud running. We support all AWS data centers and all of the servers storage networking power and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems with thousands of variables impacting the supply chain and were looking for talented people who want to help.

Youll join a diverse team of software hardware and network engineers supply chain specialists security experts operations managers and other vital roles. Youll collaborate with people across AWS to help us deliver the highest standards for safety and reliability while providing seemingly infinite capacity at the lowest possible cost for our customers. And youll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

As a Sr. Mechanical/Thermal Engineer within the Network Product Development (NPD) team you will directly shape how AWSs 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).
