Job Description

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very widely used in breakthrough enterprise initiatives such as public cloud, data science, AI, engineering innovation and IoT. Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1000+ colleagues in 70+ countries and very few office based roles. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution.

The company is founder led, profitable and growing.

This is a general selection process for software engineers focused on virtualisation and container technology - from the kernel through userspace. Apply here if you are an exceptional Go, Rust, or C/C++ software engineer and want to work on next-generation open source VMM or container technology, or related open source networking and storage.

Container, virtualisation and cloud infrastructure have become essentials of modern software deployments. We invest in open source related to application isolation, workload orchestration, system or OCI containers, micro service architecture or cloud infrastructure.

Here are some examples of projects under way at Canonical.

RustVMM has great potential as a new hypervisor for Linux. We are building a team to work on this, with an emphasis on performance, security and operability. Work in Rust and bring your expert knowledge of VMM and related kernel networking and storage capabilities.

Docker images are easy to make and publish on Docker Hub and other registries, but the quality, consistency and security maintenance of those images is broadly very poor. Canonical is in a good position to publish a portfolio of outstanding Docker images. Our Rockcraft team is designing and implementing an elevated Docker image experience for the open source community.

LXD is a modern system container and virtual machine manager that is widely used on Ubuntu, ChromeOS and other Linux platforms. LXD engineering spans the entire software stack from low-level kernel work on namespaces, confinement, security, filesystems, VMMs and networking, to the high level management REST API and CLI.

Members of the Kubernetes product team build MicroK8s for on-rails K8s, and Charmed Kubernetes for more sophisticated integration. We work on K8s itself and on the operations tooling around it.

The OpenStack team deliver Charmed OpenStack, OVN / OVS and Ceph. This work brings cloud platform technologies to large-scale computing environments.

These teams hire system level C/C++, Golang, Rust and Python developers to work on security-critical, performance-critical and mission-critical code, focused on software delivery, containers, security, sandboxing, application orchestration and management. Our teams are motivated to have a meaningful impact on modern cloud computing technologies.

Location: we have remote container and virt engineering roles in every time zone.
