Software Development Engineer II, AWS DynamoDB

Amazon DynamoDB powers many of the world"s fastest-growing businesses, including Lyft, Airbnb, and Redfin. It also powers enterprises such as Samsung, Toyota, and Capital One. Within Amazon, it runs high-traffic properties including Alexa, Amazon.com, and every Amazon fulfillment center. DynamoDB is one of the largest distributed database systems in the world. We believe it is always Day 1, and we keep improving the service and adding new capabilities.

DynamoDB is a serverless, fully managed database. It delivers consistent single-digit millisecond performance at any scale, with no servers to provision, no maintenance windows, and no downtime. Customers can create a table and scale it automatically to their most demanding workloads without having to plan capacity. During Prime Day 2026, DynamoDB handled more than 59 trillion requests over four days. It peaked at 192 million requests per second while keeping single-digit millisecond response times. The Capacity & Customer Entitlement (CCE) team builds the systems behind this. We decide how much throughput and storage each customer gets and enforce quotas and limits fairly. We also keep DynamoDB"s global fleet ahead of demand. When our systems do their job, customers grow without thinking about capacity, and DynamoDB runs efficiently at any scale.

Managing capacity for one of the largest databases in the world is a hard distributed systems problem. Our systems forecast demand across every AWS Region, plan and place capacity across the fleet, and manage the limits and entitlements that decide how far each customer can scale. We prepare DynamoDB for major events such as Prime Day and new Region launches, so capacity is in place well before customers need it. We are building fully automated capacity management from the ground up. It is a greenfield opportunity to design systems that detect, predict, and act on their own. Engineers on this team solve problems where accuracy, scale, and cost all matter at the same time, and their work shapes how customers experience DynamoDB.

Key job responsibilities

• Design, build, and operate the services that manage DynamoDB throughput, storage, quotas, and customer entitlements at global scale.
• Build automated capacity management: demand forecasting, proactive scaling, and self-healing workflows that replace manual operations.
• Build APIs and data platforms, that give DynamoDB teams and tools accurate, real-time views of capacity and usage.
• Reduce throttling, speed up limit increases, and make large-scale fleet events safe and predictable.
• Own features end to end, from design through deployment and operation, and deliver ambiguous projects with minimal guidance.
• Take part in on-call, debug issues across services, and fix root causes so problems don"t come back.
