Software Development Engineer II, Hosted Execution (HEX)

Are you passionate about building the infrastructure that powers thousands of services across Amazon? The Hosted Execution (HEX) team is looking for a passionate, result-driven, and innovative Software Development Engineer II to deliver infrastructure solutions for all types of internal Amazon services.

In this role, you will design and implement technical solutions that drive the strategic transition from legacy hosting products (HEX and Honeycomb) to AWS-native solutions, while developing innovative Cloud Development Kit (CDK) constructs that form the foundation of Amazon Stores' compute infrastructure. You'll work on dynamic, highly distributed systems in a customer-centric environment, building automation that improves developer productivity and operational excellence across the organization.

This is a unique opportunity to influence compute infrastructure decisions that impact thousands of Amazon services, working closely with partners to develop sustainable solutions that emphasize operational excellence, safety, cost efficiency, and ease of use. If you're excited about contributing to the innovations that power Amazon's next generation of computing architecture and making broad impacts across all Amazon business lines — including Stores, Kindle, Alexa, Pharmacy, and Payments — we'd love to hear from you.
