Kernel/OS Engineer, AWS EC2 Nitro Operating System

AWS EC2 Nitro powers the world's largest, fastest-growing, and most feature-rich compute cloud. Built from the ground up for virtualization at global scale, Nitro is a fully custom stack of hardware, firmware, and software that enables EC2 to support Intel, AMD, and AWS's own Graviton processors - while setting industry benchmarks for security and performance. With our Nitro System, we break apart traditional hypervisor functions like CPU virtualization, storage, and networking, and offload them to dedicated hardware and software. This enables us to deliver practically all of the resources of a server to customer instances, innovate faster, increase security, deliver new instance types, and reduce customer cost.

The Nitro Linux team owns the secure, embedded Linux environment at the heart of this system. We build and maintain the operating system that integrates with the Nitro control plane and powers live updates, metrics collection, core dump handling, and system health monitoring across AWS's global infrastructure. Linux, ash, C, lua, Rust - join us for embedded software systems at cloud scale!
