Software Development Engineer, AWS Identity, IAM Data Plane - Credentials Distribution Systems

About the role

What does it take to distribute billions of security credentials every day to every host across Amazon’s infrastructure - without ever going down? That's the challenge at the core of this role. As a Software Development Engineer on the AWS Credentials Distribution Systems (CreDS) team, you'll build and operate the IAM role credential distribution platform for Amazon's internal infrastructure — a tier-0 system that every single service team across the company depends on.

• Collaborate with partner teams across Amazon to drive credential migration and adoption goals
• Troubleshoot and resolve complex distributed systems issues across multiple layers of the stack
• Contribute to on-call rotations and contribute to incident response, root cause analysis, and corrective action follow-through
• Contribute to system design and architecture decisions, ensuring long-term scalability and maintainability
• Leverage AI tooling to improve engineering productivity, automate workflows, and raise the bar on operational efficiency
• Raise the bar for engineering quality through thorough code reviews, testing practices, and technical documentation
