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.\nCanonical 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.\nThe 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.\nWe 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.\nKernel Team projects include but are not limited to:\nUbuntu Linux kernel plan, execution, benchmarking and stress testing\nOptimised kernels for key silicon and cloud partners\nConfidential computing and next-generation security primitives\nDeveloper platforms such as Raspberry Pi and RISC-V\nEnabling Ubuntu on a wide range of embedded systems\nKernel Livepatch, which delivers critical kernel fixes without rebooting\nFIPS compliance\nReal-Time and Low Latency kernel variants and patchsets\nVirtualisation or abstraction engines\nContainer technology\nSecurity with AppArmor, SECCOMP, namespaces and more\nNetworking - in particular performance and security\nStorage - we are particularly interested in Ceph and DRBD\nWe hire candidates of all experience levels from recent university graduates through seasoned industry experts. We select those who are enthusiastic to work in multiple areas including security mitigation, feature development, patching and test. You must have outstanding academic results, a background in software engineering, be motivated to work in a distributed team and willing to travel globally twice a year for company engineering events.\nLocation: Working from home, worldwide. We have kernel teams and openings in every time zone and with the notable exception of Taipei, Taiwan, have no offices and therefore no pressure to work from an office.\nWhat your day will look like\nCollaborate regularly and proactively with a globally distributed team \nWork closely with silicon, cloud, or hardware manufacturers\nDiagnose and resolve issues in the kernel\nTake personal responsibility for a flavour of the Ubuntu Linux kernel\nImprove tooling and automation for delivery and test of Ubuntu Linux kernels\nSubmit, review, and apply kernel patches\nWhat we are looking for in you\nAn exceptional academic track record from both high school and university\nUndergraduate degree in Computer Science or STEM, or a compelling narrative about your alternative path\nDrive and a track record of going above-and-beyond expectations\nWell-organised, self-starting and able to deliver to fixed schedules\nProfessional manner interacting with colleagues, partners, and community\nAbility to communicate effectively in English, both written and oral\nSignificant programming experience in C\nSolid background with git\nBroad knowledge of the Linux kernel and kernel subsystems\nDemonstrated experience with kernel patching and debugging\nUnderstanding of Linux kernel upstream processes and release cycle\nStrong grasp of device drivers, BSP’s, and other low level system engineering\nProfessional written and spoken English \nExperience with Linux (Debian or Ubuntu preferred) \nExcellent interpersonal skills, curiosity, flexibility, and accountability \nPassion, thoughtfulness, and self-motivation \nExcellent communication and presentation skills \nResult-oriented, with a personal drive to meet commitments \nAbility to travel twice a year, for company events up to two weeks each\nAdditional skills that you might also bring\nPython and Bash scripting\nPrior experience with Ubuntu/Debian/Snap packaging\nPerformance engineering and security experience\nWhat we offer you\nWe consider geographical location, experience, and performance in shaping compensation worldwide. We revisit compensation annually (and more often for graduates and associates) to ensure we recognise outstanding performance. In addition to base pay, we offer a performance-driven annual bonus. We provide all team members with additional benefits, which reflect our values and ideals.
