Principal Engineer & Senior Principal Engineer, Distributed Systems, Distributed Systems

Description We are hiring Principal and Senior Principal Engineers to join AWS Infrastructure Services. Infrastructure Services operates like a startup that ships at hyperscale. We own the full stack - from demand forecasting algorithms and supply chain planning systems to fleet security and network architecture - and every system we build goes live supporting production infrastructure serving millions of customers. There's no handoff to another team. You see it through. As a Principal or Senior Principal Engineer here, you'll set the technical direction for the intelligent systems layer that powers AWS's data centers. That means making the calls that ripple across the entire infrastructure lifecycle: architecting distributed software that determines how efficiently we utilize billions in electrical capacity, designing supply chain automation that decides whether AWS can deliver capacity in weeks or months, driving security strategies that protect the world's most targeted infrastructure from provisioning through decommissioning, and defining network architectures that connect it all at hyperscale. You'll work across Infrastructure Services' full breadth of specializations - power utilization and capacity planning, supply chain automation and optimization, infrastructure security and fleet lifecycle management, and network engineering - bringing clarity to cross-cutting technical decisions that no single team can resolve alone. You'll mentor technical leads, raise the engineering bar, and partner directly with senior leadership across multiple VP organizations to shape our roadmap. The systems you influence will optimize power across thousands of data centers, automate supply chains managing billions in assets, secure infrastructure against nation-state threats, and connect it all through networks operating at unprecedented scale - the intelligent foundation that makes AWS possible.
