Skills
We are looking for a Sr. Software Development Engineer to design and build large-scale, next-generation Access Management systems. In this role, you will own and drive key engineering and business decisions that shape the Amazon developer experience. You'll contribute across the full software development lifecycle, including design, implementation, documentation, deployment, and operations, spanning multiple products and reaching the entire Amazon development community.
You will collaborate closely with leadership and a talented group of engineers to deliver high-impact, extensible security capabilities that unblock diverse businesses across the enterprise. Additionally, this role includes participation in an on-call rotation with the team. We prioritize building fault-tolerant systems to keep disruptions to a minimum, and when pages do occur, we work together to identify and fix the root cause, so the issue doesn't repeat.
What We are Looking For
• You challenge the status quo and find creative ways to move faster.
• You love to experiment, iterate rapidly, and embrace automation.
• You adopt AI assistants and modern tooling to build speed into your software lifecycle without compromising quality.
• You are passionate about building highly scalable and reliable systems in the cloud, or you thrive on solving complex, interesting business problems — ideally both.
• You don't need to be a security expert on day one — there is ample opportunity to learn, innovate, and deliver meaningful outcomes.
