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.

Open Source Development
- Contribute to Linux kernel improvements
- Contribute to various other open source projects
- Develop analysis frameworks and automation systems

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

We believe striking the right balance between your personal and professional life is critical to life-long happiness and fulfillment. We offer flexibility in working hours and encourage you to find your own balance between your work and personal lives.
