Join us in building the foundational infrastructure that powers Amazon's global operations. You'll work on highly distributed systems handling tens of millions of requests per minute, designing and maintaining the critical software layer that accepts, filters, and routes all web traffic from the public Internet to Amazon's websites and services. This role offers the opportunity to solve complex technical challenges while directly impacting the security and reliability that millions of customers depend on every day.
Key job responsibilities
- Develop and maintain software for high-availability systems that process millions of requests per minute, ensuring reliability and performance at scale
- Troubleshoot, debug, and resolve system alerts and issues in production environments, implementing fixes that maintain service integrity
- Design and implement tools and automation workflows that reduce manual operational tasks and enable more autonomous system operations
- Collaborate with cross-functional teams to evaluate feature requests, implement enhancements, and manage software deployments and migrations
- Participate in on-call rotations to monitor system health, respond to incidents, and support the operational needs of our infrastructure
A day in the life In this role, you'll focus on developing and operating the reverse proxy and traffic management systems that form the backbone of Amazon's connectivity infrastructure. Your day might include troubleshooting and resolving system alerts, collaborating with cross-functional teams to implement feature enhancements, and writing code that optimizes how traffic flows through our distributed network. You'll balance hands-on software development with operational responsibilities, including on-call support where you'll diagnose issues in real-time and deploy solutions to production systems. You'll also dedicate time to building automation tools and end-to-end workflows that reduce manual operational work and move us toward more autonomous systems. Throughout it all, you'll work with colleagues who are equally committed to maintaining the security, reliability, and performance that our customers expect.
