About The Position

The AWS Graviton Software team is seeking Software Engineers to optimize
performance for AWS Graviton.

Graviton delivers the best price/performance in AWS data centers. For the past 2
years, Graviton has powered the majority of new EC2 capacity and is used by over
90% of our largest customers.

You'll drive performance optimization across open source projects, internal
services, and customer applications, working on everything from Linux kernel
development to C++/Rust debugging to assembly-level optimization. Our team
optimizes a diverse range of applications including databases, web services,
games, video encoding, ML, and HPC workloads.

This doesn’t mean you have or will have all those skills, but you’ll have a
chance to learn from those who do. This is a unique opportunity to impact how
software runs in AWS, while growing your technical breadth and depth.

The role offers opportunities to work on latest CPU technology while
contributing to both AWS and the open source community.

The Graviton Software organization ports, optimizes, and develops software to
drive down the cost of adoption and operation for the AWS Graviton instances. We
pro-actively improve and upstream open source software, including Linux kernel,
operating system, compilers, libraries, and applications. We help internal and
external customers to troubleshoot and fix performance bottlenecks that prevent
them from using Graviton. We develop tools to automate most of the heavy lifting
and maintain publicly available documentation: Graviton Developer Guide on
