Junior Linux Kernel Engineer

About Canonical

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. Teams meet two to four times yearly in person, in interesting locations around the world, to align on strategy and execution.

The company is founder-led, profitable, and growing.

The Role: Junior Linux Kernel Engineer

Every year we select new junior professionals into the Canonical Kernel Team, to work on the Linux kernel for Ubuntu. 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. We select candidates that are recent university graduates or early career professionals who are enthusiastic to develop kernel-level software in multiple areas including security updates, patching, and testing. The successful candidate will have a background in software engineering, be motivated to work in a distributed team and willing and able to travel globally twice a year for company engineering events.

These are full-time positions available to prospective or recently graduated students.

Location: We have home-based Kernel Teams in every timezone.
