With extensive experience in C programming, device drivers, and OS kernel fundamentals, I am confident in my ability to contribute to optimizing Ubuntu for various SoC platforms. My background includes hands-on work with hardware-level software engineering, including BSPs and git-based development, which aligns directly with the requirements of this role. I am particularly drawn to the opportunity to collaborate with leading silicon vendors and to take ownership of delivering optimized kernel variants. As a self-starter who excels in remote environments, I am prepared to engage proactively with the global team and partners to diagnose and resolve kernel issues while improving automation and tooling. I also bring scripting skills in Python and Bash, which would aid in streamlining testing and delivery processes. I am excited about the chance to work at the forefront of open source technology and to help Canonical expand Ubuntu's hardware enablement. Thank you for considering my application. Copy ### Sample Interview Questions Describe your experience with Linux kernel development. What specific subsystems or areas have you worked on?I have contributed to the Linux kernel for over 5 years, focusing on device drivers for ARM-based SoCs, specifically in the graphics and networking subsystems. I have experience with patch submission, review processes, and maintaining out-of-tree modules for hardware enablement.How do you approach debugging a kernel crash or hang on a new hardware platform?I start by reproducing the issue with a minimal test case, then use tools like ftrace, kgdb, and kernel crash dumps (kdump) to identify the root cause. I also enable dynamic debugging and review the hardware documentation to verify register configurations and timing.Explain the process of enabling support for a new SoC in the Ubuntu kernel. What steps are involved?This involves integrating the SoC's vendor BSP, configuring the kernel to enable necessary drivers and device trees, and validating functionality across multiple releases. I also work with the vendor to test performance and stability, and submit patches upstream when appropriate.How do you manage competing priorities from multiple silicon vendors while maintaining kernel quality?I prioritize based on the impact on users and the strategic goals of Canonical. I use agile methodologies to track tasks, communicate regularly with vendors via forums and meetings, and leverage automated CI/CD to catch regressions early.Can you describe a time you had to collaborate with a remote team to solve a complex kernel issue?In a previous role, our team faced a memory corruption bug triggered by a specific DMA operation. I coordinated with the vendor's hardware engineers and my colleagues across time zones, using shared bug trackers and video calls to isolate the issue. We eventually traced it to a missing cache coherence barrier, fixed it, and revalidated the kernel. Ubuntu Linux, already the most popular Linux distribution in the world, is looking to increase its adoption even further by expanding the number of System On Chip (SoC) platforms supported natively and further optimising to ensure the highest performant experience for all users. There is a strong demand from silicon manufacturers such as NVIDIA, Xilinx, MediaTek, and Qualcomm to provide Ubuntu Linux to their customers and Canonical is looking to broaden its silicon enablement squads to meet this challenge. The Canonical Kernel Team – those responsible for the build, maintenance, and distribution of the Linux kernel for Ubuntu – are looking for individuals with a strong flair for software development at the hardware level and a passion for ensuring the most optimal performance the silicon can provide. The successful candidate will be able to prove a strong aptitude for software engineering at the hardware level. While direct experience with the Linux kernel would be a substantial advantage, it is not a hard requirement for candidates with prior background in other RTOS’ or bare-metal environments as long as direct hardware experience can be demonstrated. There are a number of work-from-home based roles available worldwide and we are looking for experience levels from early career candidates with a couple of years under their belt up through senior industry veterans. ## What your day will look like * Collaborate regularly and proactively with a globally distributed team * Work closely with our silicon vendor partners to integrate their platform support into the Ubuntu Linux kernel for their product ranges * Diagnose and resolve issues in the kernel reported by partners, customers, the community at large, and discovered by your own rigorous testing * Take responsibility for the delivery of distinct silicon-optimised variants of the Ubuntu Linux kernel to the world * Improve tooling and automation for the delivery and test of Ubuntu Linux kernels * Submit, review, and apply kernel patches, working with both internal and external upstream maintainers * Identify new means of maximising performance on partner silicon ## What we are looking for in you * Well-organised and motivated self-starter able to thrive in a remote work environment * Professional manner with colleagues, business partners, and the open-source community * Ability to communicate effectively in English, both written and verbal * Significant programming ability in C * Strong grasp of device drivers, BSP’s, and other aspects of hardware-level system engineering * Solid background with git * Understanding of operating system kernel fundamentals * Ability to travel twice a year for company events of up to two weeks length ## Additional skills that you might also bring * Python and Bash scripting ability * Prior background with the major SoC families * Ubuntu/Debian/Snap packaging * Demonstrated experience with Linux kernel patching and debugging * Solid understanding of performance optimisation for silicon platforms ## What we offer you We consider geographical location, experience, and performance in shaping compensation worldwide. We revisit compensation annually 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. We balance our programs to meet local needs and ensure fairness globally. * Home-based work environment with twice-yearly team sprints in person * Personal learning and development budget of USD 2,000 per year * Annual compensation review * Recognition rewards * Annual holiday leave * Maternity and paternity leave * Employee Assistance Programme * Opportunity to travel to new locations to meet colleagues * Priority Pass, and travel upgrades for long haul company events ## About Canonical Canonical is a pioneering tech firm at the forefront of the global move to open source.
