Description

AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we're 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 ensures 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 we're looking for talented people who want to help.

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

Within AIS and Data Center Engineering, the Mechanical Products and Services team is driving rapid innovation in mechanical cooling and controls systems used by AWS. Our designs are fundamentally changing the data center, providing operational and financial benefits that are critical to the success of the AWS business and its millions of customers. Our engineers solve challenging technology problems and take big bets on new concepts, enabling AWS services to continue to revolutionize the industry. This role provides the opportunity to work closely with our team of innovative mechanical engineering builders developing and deploying the next generation of air handling infrastructure for our data centers.

AWS is seeking a Principal, Mechanical Engineer for our team developing new infrastructure solutions that enable at-scale deployment of the latest air and liquid-cooled racks into our data centers. We are looking for an individual contributor with excellent people skills and prior air handling product development experience to define the product strategy and provide technical guidance to lead to team to execute against this strategy. This role will work closely with both AWS builders and third-party manufacturers to develop data center infrastructure solutions on our behalf.

If you have experience leading product design of mechanical products, have an extensive understanding of air-cooled solutions in data centers, and know how products should be manufactured to ensure quality and scalability, you may be a good fit. This role requires the ability to influence a team in developing detailed mechanical equipment specifications and evaluating the merit and risks of design changes.

Since Amazon has a global presence, intermittent travel will be necessary and should be expected to be approximately 30% to AWS offices, data centers, suppliers, vendors, and product validation tests. While most travel will be domestic, some international travel may be required.

Key job responsibilities

• Demonstrate strong engineering judgment in designing highly reliable air handling systems, psychrometric analysis, and air-side economization strategies for mission-critical facilities

• Direct innovative, high-performance teams developing next-generation direct evaporative cooling solutions and advanced chiller plants, managing facility thermal loads exceeding 100MW+ while achieving mechanical PUE metrics below 1.05

• Apply data-driven approaches using CFD analysis, thermal modeling software, and real-time sensor data to optimize airflow patterns, static pressure control, and air-side heat transfer optimization

• Build trust across teams by leading technical reviews of cooling system designs, maintenance procedures, and reliability improvements targeting +99.999% availability

• Utilize extensive experience in thermodynamics, psychometrics, fluid mechanics, and ASHRAE standards, with specific focus on evaporative cooling technologies including adiabatic cooling, free cooling, and advanced chiller plant optimization

• Provide strategic direction across multiple products being deployed globally in new and existing facilities exceeding 250MW+ across data center campuses

• Communicate complex cooling systems architecture through detailed control schemes, psychrometric analysis, and system performance specifications

• Collaborate with global suppliers

• Support global operations

• Incorporate multi-stakeholder feedback

- Contribute to our global knowledge base
