Senior Software Development Engineer

Come help us shape the future of one of the largest NoSQL database services on the planet! Amazon DynamoDB is one of the largest distributed database systems in the market, delivering single-digit-millisecond performance at any scale. At DynamoDB, we continue to believe it is Day 1! The DynamoDB Storage Engine team is the custodian of all customer retrievable data stored on disk in DynamoDB and owns services, components and libraries that persist customer data on disk, keep it secure and make it available for timely retrieval. We are looking for a senior software development engineer with a deep passion for storage and persistence — someone who thinks deeply about how data should live on disk, how to balance durability guarantees against performance, and who finds elegance in the engineering of reliable, space-efficient, crash-resilient storage systems. Many of the world's fastest growing businesses, such as Lyft, Airbnb, and Redfin, as well as enterprises, such as Samsung, Toyota, and Capital One, depend on the scale and performance of DynamoDB to support their mission‑critical workloads. In this role, your work will directly safeguard the durability and availability of data for these customers at planetary scale. What You Will Do Design and build high-performance, low-latency systems that operate reliably at massive scale. Optimize the read and write paths to improve throughput and tail latency while maintaining strict performance guarantees. Expand query and data‑modeling capabilities that make the database more flexible and easier for customers to use. Improve fleet efficiency and capacity utilization through smarter resource management. Build automation and tooling that increase operational excellence and prevent customer‑impacting issues before they occur. Lead technical designs, drive cross‑team initiatives, and mentor engineers through design and code reviews. About the team AWS values diverse experiences.
