Are you passionate about solving complex engineering challenges that impact millions of people worldwide? Do you thrive when leading technical innovation in collaborative, diverse environments? Have you ever wondered what it takes to keep the global cloud running seamlessly? Whether your path to mechanical engineering was traditional or winding, we want to hear from you.
We seek a Principal Mechanical Engineering leader with extensive liquid cooled product development experience, proven ability to influence technical teams, and a track record of delivering complex mechanical products from specification through manufacturing and deployment.
AWS Infrastructure Services is the backbone of the global cloud, designing, planning, delivering, and operating all AWS infrastructure that keeps millions of customers connected to the innovation they depend on. As a Principal Mechanical Engineer, you will be a technical leader driving transformational change in how we approach mechanical cooling and controls systems across our global data center footprint.
As a Mechanical Engineering Principal, you will serve as a Subject Matter Expert and technical leader within the Mechanical Products and Services team, architecting solutions that fundamentally reshape data center operations while delivering measurable operational and financial benefits. You will own complex, ambiguous problems spanning multiple engineering disciplines and drive technical decisions that impact AWS's global infrastructure strategy.
You will lead the development of next-generation liquid cooled infrastructure solutions, taking ownership of product roadmaps from concept through at-scale deployment. This includes pioneering liquid-cooled and air-cooled rack technologies that enable AWS to maintain its competitive edge. Your technical expertise will guide cross-functional teams in making critical design decisions, evaluating trade-offs, and managing technical risks across complex mechanical systems.
As a principal engineer, you will influence and mentor engineering teams while collaborating with AWS builders, third-party manufacturers, and global stakeholders. You will establish technical standards, drive best practices, and ensure our mechanical solutions meet the highest standards for safety, security, and cost-effectiveness at unprecedented scale.
This role requires approximately 30% travel to AWS offices, data centers, supplier facilities, and validation sites globally. You will represent AWS's technical vision to external partners and drive alignment across our international operations.
