Technology Focus

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++ 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 are essential for 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 underway at Canonical:

• RustVMM – a new hypervisor for Linux focused on performance, security and operability.
• Rockcraft – an elevated Docker image experience for the open source community.
• LXD – a modern system container and virtual machine manager used on Ubuntu, ChromeOS and other Linux platforms, covering low‑level kernel work, filesystems, VMMs, networking, and higher‑level REST API and CLI.
• Kubernetes (MicroK8s & Charmed Kubernetes) – building on‑rail K8s, Charmed Kubernetes, and operations tooling.
• OpenStack (Charmed OpenStack, OVN/OVS, Ceph) – delivering cloud platform technologies to large‑scale computing environments.

These teams hire system‑level C/C++, Go, 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.
