Own the rules engine that decides who gets billed for every AWS transaction, worldwide

This is an SDE role on AWS Invoicing Entities, the team that owns the systems defining, storing, resolving and syncing entity/billing-relationship data behind every AWS commerce transaction. You'd design distributed services across DynamoDB, OpenSearch, Kinesis, SNS, AWS Glue, and cross-region replication, and extend a Seller-of-Record rules engine with direct legal/tax/compliance consequences.
