Want to help make sure every AWS customer's invoice is right — every single one, in every region, every day? The AWS Bill Adjustments team is modernizing how refunds, credits, and invoice corrections are processed at AWS scale — combining classical distributed-systems engineering with Generative AI and agentic workflows to dramatically improve the customer billing experience. This is an opportunity to do meaningful, mission-critical engineering: building services that AWS customers and AWS Customer Service teams rely on daily, deployed across every AWS region. You'll work in a team where engineers own features end-to-end, and partner closely with adjacent AWS Billing platform teams. The ideal candidate brings strong distributed-systems fundamentals, makes sound technical trade-offs across reliability, scalability, and maintainability, and writes code that is secure, well-documented, and built to last. You value written communication and shared ownership, and you're excited about what Generative AI means for the future of production software. If you want to work on real distributed-systems problems with direct customer impact — and grow into the AI-augmented future of operational software — we'd love to talk. Key job responsibilities - Design, build, and operate distributed services that handle billing adjustments — refunds, credits, and invoice corrections — for AWS customers worldwide - Build and integrate Generative AI and agentic workflows into our operational tooling, working with foundation models and agent frameworks to augment how billing issues are resolved - Partner with engineers on adjacent AWS Billing platform teams, our Product Manager, and Tech Lead to align on requirements, scope, and design across cross-functional initiatives - Make sound technical trade-offs across reliability, scalability, observability, and maintainability for production services deployed across multiple AWS regions - Own features end-to-end — from requirements and design document
