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.

About the team
Annapurna Labs, part of AWS, created Graviton as a strategic ARM-based CPU
initiative to revolutionize cloud computing at Amazon scale. Graviton instances
deliver superior performance, cost efficiency, and reduced carbon footprint

customer and internal team migrations to Graviton by optimizing and stabilizing
software ecosystems, contributing to open source projects (including Linux
kernel, operating systems, compilers, libraries, and ML frameworks), developing
automated services, and maintaining public documentation. Our work enables AWS
customers and Amazon teams to leverage Graviton's advantages in performance,
cost, stability, and energy efficiency.
