Job Summary

Own, operate, and optimize DynamoDB workloads in production, including data modeling, capacity strategy, GSIs/LSIs, TTL, Streams, and multi-region patterns. Design, deploy, and maintain relational and non-relational databases with sharding, indexing, and performance tuning. Leverage AWS services across the data stack to build reliable, observable, and secure solutions. Implement automation-as-code for schema and capacity changes.
