The Amazon Web Services (AWS) Identity team builds, operates, and innovates the identity, authentication, and authorization stack for the AWS cloud. Our mission is to push the technical boundaries to enable AWS customers to run their business workloads confidently and securely. As part of this mission, AWS Resource Access Manager (RAM) enables customers to securely share their AWS resources across accounts, organizations, and organizational units — simplifying multi-account governance while maintaining fine-grained access controls. AWS RAM allows customers to centrally manage resource sharing at scale, eliminating the need to create duplicate resources in every account. As AWS grows and customers adopt increasingly complex multi-account strategies, RAM must evolve to support new resource types, richer sharing policies, and higher-order scalability demands. We are looking for strong software engineers to build the next generation of resource sharing infrastructure. Individuals interested in this position should have experience building high-performing, reliable systems in a distributed, multi-tenant environment at a fast pace. You'll thrive in this role if you are passionate about building highly available, fault-tolerant distributed systems that operate seamlessly across organizational boundaries. You care deeply about API design that makes complex sharing workflows intuitive — making "the right thing, the easy thing." You think about the customer experience when weighing engineering trade-offs, whether that's designing retention behaviors for departing accounts, enabling resource discovery, or ensuring consistent state across asynchronous workflows. You value operational excellence — advocating for actionable alarms, eliminating toil, and squashing flaky tests before they erode confidence. You also believe that having fun and tackling hard problems go hand-in-hand: event-driven architectures, eventual consistency challenges, high-throughput resource indexing, and building APIs that scale to millions of shared resources — all while maintaining the security and reliability customers depend on.
