With a strong background in Python, Linux kernel internals, and automated testing, I am well-prepared to take ownership of the kernel testing strategy and infrastructure. In my previous role, I designed and maintained test suites for multiple kernel versions, implemented CI/CD pipelines, and conducted performance and fuzz testing to ensure reliability. I am familiar with tools like LTP, kselftest, and syzkaller, and I thrive in collaborative, globally distributed teams. I am eager to contribute to the quality assurance of Ubuntu kernels and support Canonical's commitment to long-term stability. Thank you for considering my application. Copy ### Sample Interview Questions How would you design a test plan for a new kernel feature that needs to be validated across multiple architectures and kernel versions?I would start by understanding the feature's requirements and potential impact areas. Then, I would identify functional tests from upstream, create stress and performance benchmarks, and ensure regression tests are in place. I'd automate the tests in a CI/CD pipeline, covering all supported architectures and kernel versions, and integrate code coverage analysis to identify gaps.Describe your experience with kernel fuzzing. Which tools have you used, and how did you set up a fuzzing harness?I have experience with syzkaller and Trinity. For syzkaller, I would configure it with the target kernel, enable coverage instrumentation, and run it on a set of VMs. I would monitor crashes and bisect to find the triggering commits. I also developed custom fuzzers for specific subsystems by using ioctl fuzzing or syscall introspection.How do you ensure test suites remain effective across long-term support kernels that are updated over years?I maintain the test suites in a version-controlled repository, regularly updating them with new test cases from upstream and community contributions. I use parameterization to handle kernel version differences and run regression tests against each kernel branch. Periodic reviews of coverage and bug reports help identify gaps.Explain a time you identified a critical kernel bug through testing. What methods did you use?While running stress-ng with memory pressure tests, I noticed a rare crash in the OOM killer. I used ftrace to capture the events and bisected to a recent memory management patch. I then wrote a specific test case to reproduce it and reported the bug with detailed steps and a proposed fix.How do you prioritize testing efforts when there are multiple kernel versions and limited resources?I prioritize based on risk: new features, security patches, and known problematic subsystems get higher coverage. I use risk assessment from past bugs and community reports. I also automate as much as possible to scale, and focus manual testing on complex scenarios that are hard to automate. Ubuntu is the most widely used Linux distribution in the world, delivering kernels across a vast matrix of versions, architectures, and configurations – with up to 15 years of security and maintenance commitments for Long Term Support (LTS) releases. Ensuring the quality and reliability of these kernels demands a dedicated, systematic approach to testing at scale. The Canonical Kernel Team is looking for a Test Engineer to take ownership of our kernel testing strategy and infrastructure. You will design and maintain test plans covering functional correctness, stability, performance, and security. You will build and evolve automated test frameworks – including stress testing, fuzzing, code coverage analysis, and regression detection – that not only must remain effective across many concurrently supported kernel versions spanning years of maintenance, but must be able to scale with the high demand for Ubuntu kernels (currently more than 160 under active support). The successful candidate will bring strong Python skills, familiarity with Linux kernel internals, and experience building test infrastructure that scales. You will work closely with kernel engineers to catch regressions early, validate fixes, and ensure every kernel we ship meets the highest standards of reliability. Location: This role will be based remotely in the APAC region, except for Taipei, Taiwan, and Beijing, China, which are office-based locations. ## What your day will look like * Design, develop, and maintain comprehensive test plans covering functional correctness, stability, performance, and security for Ubuntu Linux kernels * Build and improve automated test infrastructure for continuous kernel quality validation across multiple kernel versions and architectures * Maintain long-lived test suites that evolve alongside Ubuntu’s many concurrently supported kernel versions spanning years of maintenance * Develop and maintain CI/CD pipelines for continuous kernel quality validation * Conduct performance benchmarking and regression detection across kernel releases * Measure and improve kernel code coverage, identifying gaps in test coverage and creating tests to address them * Execute and analyze stress tests covering CPU scheduling, memory management, I/O subsystems, networking, and filesystem workloads * Develop and maintain fuzzing harnesses to discover kernel vulnerabilities and reliability issues using tools such as syzkaller, Trinity, or custom fuzzers * Collaborate regularly and proactively with a globally distributed team * Contribute to upstream test suites and testing frameworks * Document test methodologies, results, and coverage gaps ## What we are looking for in you * Significant programming experience in Python * Experience with test frameworks such as LTP, kselftest, xfstests, stress-ng, fio, or similar * Experience designing and executing system-level tests: functional, stress, performance, or regression testing * Familiarity with CI/CD systems (Jenkins, GitHub CI, or similar) * Experience maintaining test suites over long periods, adapting to evolving software across multiple supported versions * Familiarity with Linux (Ubuntu or Debian preferred but not required), Linux kernel internals and subsystems * Experience with Linux systems administration and automation * Solid background with git * Well-organized, self-starting and able to deliver to fixed schedules * Professional written and spoken English with excellent communication skills * Ability to travel twice a year, for company events up to two weeks each ## Additional skills that you might also bring * Familiarity with kernel fuzzing tools and techniques (e.g. syzkaller, Trinity, AFL, or custom harnesses) * Experience with code coverage instrumentation (e.g. gcov, kcov, LLVM source-based coverage) * Knowledge of kernel tracing and observability tools (e.g. ftrace, perf, bpftrace, eBPF) * Familiarity with static analysis tools (e.g. sparse, smatch, Coccinelle) as part of a testing workflow * Experience with fault injection frameworks (e.g. failslab, fail_make_request) for reliability testing * Prior experience with test infrastructure at scale (provisioning, orchestration, result aggregation) * Experience with Ubuntu/Debian packaging or Snap * Knowledge of virtualization technologies (KVM, QEMU) and container runtimes * Cloud infrastructure experience (AWS, GCP, Azure, or OpenStack) * Prior involvement with open source testing communities or projects ## What we offer you Your base pay will depend on various factors including your geographical location, level of experience, knowledge and skills.
