Linux Kernel Engineer - Ubuntu

Canonical is a leading provider of open source software and operating systems to the global enterprise and technology markets. Our platform, Ubuntu, is widely used in enterprise initiatives such as public cloud, data science, AI, engineering innovation, and IoT. Our customers include leading public cloud and silicon providers and industry leaders across sectors. Canonical has a distributed global team with 1200+ colleagues in 75+ countries and very few office-based roles. Teams meet two to four times yearly in person to align on strategy and execution.

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 desktop / server systems to large scale cloud environments, mainframes and supercomputers. We care most about hardware and virtualization enablement, security, reliability and performance. Our focus is production readiness and performance for the latest patch-sets, rather than subsystem maintenance or evolution.

Kernel Team projects include but are not limited to the following :

• Ubuntu Linux kernel plan, execution, benchmarking and stress testing
• Optimized 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, delivering kernel fixes without rebooting
• FIPS compliance
• Real-Time and Low Latency kernel variants and patch-sets
• Virtualization or abstraction engines
• Container technology
• Security with AppArmor, SECCOMP, namespaces and more
• Networking – performance and security
• Storage – Ceph and DRBD

We hire candidates of all experience levels from recent graduates to seasoned industry experts. You should be enthusiastic about working in multiple areas including security mitigation, feature development, patching and testing. You must have outstanding academic results, a software engineering background, be motivated to work in a distributed team, and be willing to travel globally twice a year for company engineering events.

Location : 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.
