Ubuntu Linux Kernel Engineer

Ubuntu Linux is already the most popular Linux distribution in the world, and its mission is to remain at the forefront of the global software ecosystem. As the industry evolves, we are expanding our support for a wider array of System on Chip (SoC) platforms to ensure that every user receives a high-performance and reliable experience. There is growing and vital demand from major silicon manufacturers such as NVIDIA, AMD, Qualcomm, MediaTek, and Renesas to provide Ubuntu Linux as the foundational platform for their next-generation hardware.

The Canonical Kernel Team is responsible for the build, maintenance, and distribution of the Linux kernel for Ubuntu. We are looking for engineers who share our passion for building high-quality, robust software foundations that others can rely upon. This role sits at a critical junction in the software stack, ensuring that the underlying hardware is seamlessly integrated, optimized and prepared to meet the demands of modern computing.

While direct experience with the Linux kernel would be an advantage, it is not a hard requirement. Candidates with RTOS or bare-metal experience and demonstrable hardware experience are encouraged to apply.

We welcome applications from engineers at various stages of their careers, from those beginning their journey in hardware-level development to seasoned industry veterans.
