  About the team

We're the AWS Identity and Access Management (IAM) data plane team. We build and operate one of the largest and most important software systems in the world – one that is used by every AWS customer, makes authorization decisions about every AWS API request, and needs to scale with all other AWS services.

Security is the #1 concern and requirement for customers as they evaluate moving their workloads and resources to the cloud. AWS Identity and Access Management (IAM) enables customers to secure their workloads in the cloud by providing authentication and authorization mechanisms along with customer-facing tooling. With the growth of AWS, the workloads and access pattern keep evolving and therefore demanding the next order of magnitude for scalability.

Our team is dedicated to supporting new members. We have a broad mix of experience levels and tenures, and we're building an environment that celebrates knowledge-sharing and mentorship. Our senior members enjoy one-on-one mentoring and thorough, but kind, code reviews. We care about your career growth and strive to assign projects that help our team members develop your engineering expertise so you feel empowered to take on more complex tasks in the future.
