Principal Physical Design Engineer , Data Center Engineering

Join AWS Data Center Engineering and play a critical role in delivering hyperscale infrastructure at scale. As a Senior Engineer, you'll drive the physical design of data center buildings—from site planning through permitting and construction—translating capacity demands into efficient, repeatable building designs that power AWS's cloud infrastructure. You'll contribute to innovation in high-density AI/HPC environments and help refine architectural standards that balance performance, cost, and rapid deployment. Working across electrical, mechanical, and structural disciplines, you'll evaluate trade-offs and propose solutions that support AWS's growth. You'll collaborate with cross-functional teams to improve constructibility, streamline delivery timelines, and advance sustainable, energy-efficient design. This is an opportunity to contribute meaningfully to infrastructure that serves millions of customers worldwide while tackling complex engineering challenges. Key job responsibilities Physical Design Delivery: Drive site planning, architectural development, and permitting through construction for assigned projects, translating capacity demands into efficient, scalable building designs Standardization & Efficiency: Contribute to the development and refinement of architectural standards for data center layouts, modular construction approaches, and phased expansion strategies, identifying opportunities to improve density, cost, and deployment speed Systems Integration: Deliver integrated designs across electrical, mechanical, and structural disciplines, evaluating trade-offs between cooling strategies, structural performance, and environmental requirements with data-driven analysis Permitting & Compliance: Support regulatory engagement and permitting strategies across assigned geographies, ensuring designs meet building codes, fire/life safety standards, and environmental regulations Constructibility: Collaborate with construction, procurement, and supply chain teams to improve site logistics, support prefabrication strategies, and identify bottlenecks that impact time-to-market Cross-Functional Collaboration: Partner with architecture, engineering, and construction teams to drive alignment on priorities and navigate complex trade-offs within your project scope Innovation: Contribute to continuous improvement through lessons learned, industry benchmarking, and exploration of high-density design, sustainable building strategies, and advanced construction techniques A day in the life About AIS AWS Infrastructure Services (AIS) 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 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 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. About the team About AWS Diverse Experiences AWS values diverse experiences.
