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 other industry leaders. The company is a pioneer of global distributed collaboration, with 1200+ colleagues in 75+ countries and very few office‑based roles.

We are hiring a Senior Site Reliability / Git Ops Engineer to join the Information Systems (IS) team.
