Our team owns services that are critical to how Amazon operates in the cloud — they underpin account lifecycle operations, policy enforcement, and organizational governance for millions of AWS accounts. You'll build and operate services that are foundational to Amazon's security posture and cloud operations.
The Account Lifecycle and Federation at Amazon (ALFA) team is looking for a Software Development Engineer II who is passionate about building large-scale distributed systems that power AWS account management and governance.

You'll be expected to develop robust, highly available distributed systems, drive technical decisions, and deliver solutions that operate at Amazon scale. You'll work across the full software development lifecycle — from design through deployment and operations — and collaborate with partner teams across security, infrastructure, and AWS services.
