AWS Invoicing Entities owns the systems that define, store, resolve, and surface the entities and billing relationships behind every AWS commerce transaction. We ensure every transaction is attributed to the correct seller, buyer, broker, and billing family — and we enable AWS to expand into new markets by launching new Sellers of Record safely and efficiently. Our services are Tier 1 dependencies for the AWS billing pipeline: Tax, Invoice, Payments, Bill Computation, and Cost Allocation all depend on data we produce. We operate at massive scale across all AWS partitions and regions. Key job responsibilities - Design and build distributed services that store, resolve, and synchronize entity data across AWS's global infrastructure (DynamoDB, OpenSearch, Kinesis, SNS, AWS Glue, cross-region replication). - Develop and extend the rules engine that determines the correct Seller of Record for every AWS transaction - a system where correctness has direct legal, tax, and compliance implications. - Own the full lifecycle of features: design, implementation, testing, deployment, and operational excellence in production. - Improve the reliability and performance of Tier 1 billing-path services that process millions of events daily. - Build tooling and automation that reduces the developer effort required for Commerce Platform market expansions from weeks to near-zero. - Collaborate with partner teams across Commerce Platform (Tax, Invoice, Payments, Organizations) to evolve shared entity models and APIs. - Mentor junior engineers through code reviews, design discussions, and operational best practices. About the team - High impact, high visibility - Your code determines the legal entity on every AWS invoice worldwide. - Greenfield + modernization - We're consolidating fragmented legacy systems into a unified entity platform with modern, configurable architecture. - Scale - Tier 1 services processing billing events for millions of AWS accounts across all regions and partitions
