Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is very 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 1200+ colleagues in 75+ countries and very few office-based roles.

If you’ve enjoyed operating systems in your coursework or current role, you are confident in your ability to write high quality C and possibly Rust, and are ready to take the plunge and see how it all works, then this would be a great place to pursue your next career stage. We are a global team working to ship the world's most widely used Linux kernel, across the very latest silicon and cloud, where you can apply and grow your software engineering skills.

The Canonical Kernel Team builds and maintains all supported Ubuntu Linux kernels for a variety of platforms and architectures from small embedded devices to standard desktop/server systems to large-scale cloud environments. In your first year you will tackle serious initiatives, which include but are not limited to:
