Kernel Engineer

This is a general track for applications to any team at Canonical that works with the Linux kernel, across all seniority levels. Apply here if you are an exceptional software engineer who wants to work on both stable and cutting edge Linux kernels for Ubuntu and its wider ecosystem. Canonical has a large and rapidly growing kernel team that underpins Ubuntu and open source more widely across a very wide range of hardware and use cases. We partner with the biggest kernel contributors - the silicon companies - to ensure that their work reaches the widest possible audience as quickly as possible, with a 10 year enterprise security commitment. The Canonical Linux Kernel Organization has teams in every time zone. We have opportunities for technical leadership, engineering management, and engineering directorships. The team is responsible for all supported Ubuntu Linux kernels, on all platforms and architectures from small embedded devices to standard desktop/server systems to large scale cloud environments, mainframes and supercomputers. We care most about hardware and virtualization enablement, security, reliability and performance. There are a number of areas where we lead upstream, but for the most part we are interested in ensuring production readiness and performance for the latest patchsets, rather than subsystem maintenance or evolution. Kernel Team projects include but are not limited to: • Ubuntu Linux kernel plan, , benchmarking and stress testing • Optimised kernels for key silicon and cloud partners • Confidential computing and next-generation security primitives • Developer platforms such as Raspberry Pi and RISC-V • Enabling Ubuntu on a wide range of embedded systems • Kernel Livepatch, which delivers critical kernel fixes without rebooting • FIPS compliance • Real-Time and Low Latency kernel variants and patchsets • Virtualisation or abstraction engines • Container technology • Security with AppArmor, SECCOMP, namespaces and more • Networking - in particular performance and security • Storage - we are particularly interested in Ceph and DRBD
