System Development Engineer II, AWS Traffic Engineering

Amazon Dev Center U.S., Inc.
 Seattle, WA


Job summary

AWS Traffic Engineering’s goal is to provide a one-stop-shop for all things throttling - starting from rule configuration, to enforcement at the network and application layer, and lastly analytics/analysis/verification on production data. The Throttle Enforcement team is responsible for developing and maintaining the AWS Throttling backend enforcement systems. These systems give AWS Service owners near infinite throttle scaling with virtually zero latency impact.

Come and join AWS Traffic Engineering! We’re a relatively new team building out systems that will give anyone owning services within AWS the ability to manage throughput and protect their service from downtime due to excessive load. We stand to protect the largest AWS services operating at the highest scale in the cloud. This is a challenging problem space, operating at the limits of scale in the cloud. We make use of cellular architecture to reduce blast radius. We write many services in Rust to achieve our required high throughput. We push ourselves to reduce our external dependencies to keep a high level of stability. This is your opportunity to work on a system that will improve availability for nearly every system in AWS. The chance to make a large impact across the company is immense!

AWS has the most services and more features within those services, than any other cloud provider–from infrastructure technologies like compute, storage, and databases–to emerging technologies, such as machine learning and artificial intelligence, data lakes and analytics, and Internet of Things. AWS Traffic Engineering is situated in the AWS Platform organization. AWS Platform is the glue that holds the AWS ecosystem together. Whether its Identity features such as access management and sign on, cryptography, console, builder & developer tools, and even projects like automating all of our contractual billing systems, AWS Platform is always innovating with the customer in mind. The AWS Platform team sustains over 750 million transactions per second.

We’re looking for builders to solve real world problems on a global scale, own their systems end-to-end and influence the direction of our technology that impacts hundreds of millions customers around the world. At Amazon an SysDE can expect to design flexible and scalable solutions, and work on some of the most complex challenges in large-scale computing by utilizing your skills in data structures, algorithms, and object oriented programming. Joining AWS Traffic Engineering offers you the opportunity to work on a small, diverse and vibrant development team building secure, reliable, and scalable features that help AWS services to be more resilient.

You will have the opportunity to drive mission critical projects, work with senior and principal engineers and mentor junior level developers. You will get in on the ground floor of building throttling software systems that are core to the operation of AWS!
