We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we’re looking for talented people who want to help. You’ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You’ll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And you’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion.

This position is based in Herndon, VA. Key job responsibilities - Design and build server-side APIs and asynchronous workflows in Java and Kotlin that operate at EC2 scale across all AWS regions - Own services end-to-end: design, implementation, testing, deployment, and production monitoring - Troubleshoot and root-cause customer-impacting issues across distributed systems - Write and review design documents for new features and system improvements - Mentor junior engineers through design reviews and code reviews - Participate in on-call rotations and drive operational improvements to improve availability - Build and maintain automation tooling in Python and Ruby to support deployment safety and fleet operations A day in the life On a typical day, you might root-cause a customer-reported API failure across multiple services, whiteboard a concurrency design with a senior engineer, or pair with a teammate on a tricky debugging session. You own your services end-to end: design, code review, deployment, and production monitoring. You'll collaborate with peers and senior engineers on system design, mentor junior engineers, and raise the bar in code reviews. On-call rotations give you direct exposure to how your services behave in production at EC2 scale. Expect a mix of heads-down coding and collaborative design sessions.
