Job description

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. Your work ensures that hosts receive short‑lived, least‑privilege credentials seamlessly, eliminating the operational burden of credential rotation at Amazon’s scale. Your primary focus will be keeping this system secure, scalable, and resilient—designing for failure and driving automation. You’ll also work backwards from internal customers to simplify credential management, building features and tooling that make adoption seamless and effortless for service teams.

Key job responsibilities

• Design, build, and operate a tier‑0 credential distribution system that serves every service team across Amazon’s internal infrastructure
• Own and continuously improve system reliability, scalability, and security—proactively identifying risks and building mechanisms to prevent recurring issues
• Work backwards from internal customers to simplify credential management, building features and tooling that make adoption seamless and effortless
• Drive operational excellence through automation, monitoring improvements, and runbook development—reducing operational toil and improving mean time to resolution
• 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
• Participate in 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

Basic Qualifications

• 3+ years of non‑internship professional software development experience
• 2+ years of non‑internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• 1+ years of software development engineer or related occupational experience
• 1+ years of designing and developing large‑scale, multi‑tiered, multi‑threaded, embedded or distributed software applications, tools, systems, and services using: C#, C++, Java, or Perl experience
