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. In your first year you will tackle serious initiatives, which include but are not limited to:

• Third-party driver integration and distribution, such as graphics
• Expanded driver support for bleeding-edge PC platforms

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 early career candidates (1-3 years industry experience), recently graduated university students, or university students with less than 3 months before graduation. The Kernel Team is currently not offering any part-time or internship roles.
