Containerization & Virtualisation Engineer

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is 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 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, virtualization and cloud infrastructure are essentials of modern software deployments. We invest in open source related to application isolation, workload orchestration, system or OCI containers, microservice architecture or cloud infrastructure.

Here are some examples of projects underway 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.
• 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 widely used on Ubuntu, Chrome
  
  OS and other Linux platforms. LXD engineering spans the entire software stack from low‑level kernel work on name spaces, confinement, security, file systems, VMMs and networking, to the high level management REST API and CLI.
• Micro K8s is built by the Kubernetes product team for on‑rails Kubernetes and Charmed Kubernetes. We work on K8s itself and on operations tooling around it.
• Open Stack team delivers Charmed Open Stack, 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.

We have remote container and virt engineering roles in every time zone.
