- Cambridge, United Kingdom
The Development Center in Cambridge
In 2018 EC2 expanded its operations to Cambridge by introducing a new Kernel and Operating System (KaOS) team in this location, in addition to our offices in Dresden, Germany and Bucharest, Romania.
The KaOS team develops and maintains the hypervisors and Linux kernels present in all EC2 servers, as well as various other low-level components, with particular focus on security, availability and performance; with continued research investment in self-healing, live updates, scheduling, networking, block devices, and much, much more.
Some of our recent innovations include the Nitro Hypervisor, core of the Nitro System, and the Firecracker MicroVM. More information about the Nitro system is available at:

The Cambridge KaOS/EC2 team has a wide charter, with focus on Hypervisor (Xen and KVM), and Linux Kernel (Networking, Block devices, IOMMU, scheduling, security, etc) development. While we are just starting, one thing is clear to us: our approach to software development is one of upstream first, Open Source first.
Amazon is looking for an experienced low-level developer with Linux Kernel or hypervisor experience for a Kernel and Operating System team. As part of the team, you will be given the chance to have a significant impact on our systems, our business and most importantly our customers.
