System Development Engineer, DynamoDB

Job ID: | Amazon Development Center U.S., Inc. Imagine a system that stores petabytes of customer data and handles peaks of more than 20 million requests per second, responding in single‑digit milliseconds. Imagine the number of servers required to power such a system. Now imagine the high‑performance network infrastructure required to ensure such a system operates with near‑perfect availability at this low latency. The Amazon DynamoDB Networking Technologies team owns DynamoDB's border networking, ensuring low latency and high availability. The systems we own are high scale and high performance: they must not add overhead to the extremely low latencies our customers expect. They also must be fault tolerant: network failures are inevitable, but our systems ensure that DynamoDB customers see no impact when failures occur. We are looking for an experienced systems development engineer who is interested in building systems that balance load, manage heat, and adapt to failures, all without human intervention at a massive scale. DynamoDB is a key‑value and document database that delivers single‑digit‑millisecond performance at any scale. As a fast‑growing service at the core of the AWS Cloud, our business and engineering decisions have widespread impact across AWS, Amazon, and beyond. 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.
