Containerization & Virtualisation Engineer

Home based - Americas, Albany

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, as well as industry leaders in many sectors. The company has over 1,000 colleagues in 70+ countries and very few office‑based roles, with teams meeting in person two to four times yearly in interesting global locations to align on strategy and execution.

Canonical 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++ developer 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 to modern software deployments. We invest in open‑source projects around application isolation, workload orchestration, system or OCI containers, micro‑service architecture, and 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, emphasising performance, security, and operability. Your work will be in Rust, pushing your expert knowledge of VMM, kernel networking, and storage capabilities.

The Rockcraft team is designing and implementing an elevated Docker image experience for the open‑source community, addressing quality, consistency, and security of Docker images on Docker Hub and other registries.

LXD is a modern system container and virtual machine manager widely used on Ubuntu, ChromeOS, and other Linux platforms. LXD engineering spans the entire stack, from kernel name spaces, confinement, security, file systems, VMMs, and networking to high‑level REST APIs and CLI.

Members of the Kubernetes product team build MicroK8s and Charmed Kubernetes. We work on K8s itself and on operations tooling around it.

The Open Stack team delivers Charmed Open Stack, OVN/OVS, and Ceph, bringing cloud platform technologies to large‑scale computing environments.

These teams hire system‑level C/C++, Go, Rust, and Python developers for security‑critical, performance‑critical, and mission‑critical code around containers, security, sandboxing, orchestration, and management.
