Sr. Software Development Engineer , DynamoDB Storage Data Plane

Overview In this role, you will own the on-disk storage layer of the DynamoDB storage engine, shaping durable and efficient data persistence. You will design compact on-disk representations for in-memory structures and evolve storage formats to balance performance and footprint. You will build crash recovery, data integrity, and resilience mechanisms to safeguard customer data at scale. You will mentor teammates and influence long-term storage architecture while collaborating with cross-functional partners. This opportunity lets you impact planet-scale storage durability and performance in a world-class service.
