Software Dev Engineer I, Annapurna Labs

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 3 years, Graviton has powered the majority of new EC2 capacity and is used by over 98% 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.
