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

Principal And Senior Principal EngineersWe 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.Key job responsibilities:Deliver strategic technical projects and architect next-generation infrastructure systems at AWS scaleLead architecture and engineering strategy across one or more domains: power utilization, supply chain automation, infrastructure security, or network engineeringDrive large-scale architectural transformations, defining technical standards and solving complex challenges at unprecedented scale and complexityPartner with senior leadership across multiple organizations to influence cross-organizational product and technical strategyMentor and guide engineers while solving complex technical challenges hands-onWork cross-functionally with Principal Engineers and teams across Infrastructure Services' specializations — from capacity planning to fleet securityScout and recruit top technical talent, actively growing the engineering communityDrive a strong engineering excellence and operational culture across all products and teamsShape technical direction for systems critical to delivering and operating production infrastructure that powers AWSBalance technical expertise with strong analytical skills to make informed architectural decisionsAbout the team:AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure.
