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, we leverage customer obsession and technologies to help customers set appropriate access controls across all their AWS environments. AWS Identity and Access Management (IAM) enables customers to secure their workloads in the cloud by providing authentication and authorization mechanisms. With the growth of AWS, the workloads and access patterns keep evolving, demanding the next order of magnitude scalability. We are looking for strong software engineers to build the next generation of IAM systems. Individuals interested in this position should have experience building high-performing, reliable systems in a complex, multi-tenancy, and distributed environment in a fast-paced environment. Youll thrive in this role if you are interested in building highly available, fault-tolerant distributed systems, low latency request processing, and p 100 anomalies. You are capable in one or more programming languages and open to learning new ones. You include customer experience when discussing engineering alternatives and value creating APIs that make "The right thing, the easy thing." You value operational sustainability and advocate for eliminating flaky tests as soon as possible. You also think having fun goes together with tackling hard problems like supercomputing, high availability, streaming, and building loosely coupled micro-services all while continuing to securely and reliably handling massive traffic with millisecond latency. About the team. We're a diverse team that's intentional about building an inclusive culture. Our members are active across Amazon's many affinity groups spanning a wide range of backgrounds and communities. We value work-life balance and offer flexible hours our on-call rotation is roughly one week every two months, and we invest in fault-tolerant systems so pages are rare. When they happen, we fix root causes together. We're committed to your growth through hands-on mentorship, thoughtful code reviews, and projects chosen to stretch your skills and advance your career.
