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. We collaborate with 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 at interesting locations around the world to align on strategy and execution. The company is founder‑led, profitable and growing.
