AI SummaryCanonical, the company behind Ubuntu, is seeking an experienced Software Engineer to build and maintain a portfolio of Ubuntu-based container images. This role focuses on developing robust container images, automating CI/CD pipelines, writing tools for security compliance, and engaging with the open-source community. The position is fully remote within EMEA, with up to 15% global travel, and requires deep knowledge of Python, Linux, and container orchestration tools like Docker and Kubernetes. As part of a growing team, the engineer will contribute to fast-moving products like Rocks (OCI images) and mentor junior team members. This is an opportunity for a senior engineer who is passionate about open source and shaping high-quality container solutions. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 4/5EasyHard ### Pace & Pressure 4/5RelaxedFast-paced ### Autonomy Level 4/5GuidedFull ownership ### Communication Load 4/5IndependentCollaborative AI insightThis role demands a high level of technical expertise in Python, container technologies, CI/CD, and Linux administration, alongside experience in mentoring and open-source collaboration. The complexity of building secure, scalable container images and leading junior engineers justifies a difficulty rating of 4, as it goes beyond typical mid-level software engineering but does not require the strategic scope of a principal-level role. ## Salary analysis Estimated compensation compared with the broader US market for similar roles.

With extensive experience in Python development, CI/CD automation, and container technologies like Docker and Kubernetes, I am excited about the opportunity to contribute to Ubuntu-based container images and drive open-source adoption. In my previous roles, I have built and maintained scalable containerized applications, implemented robust CI/CD pipelines, and collaborated with cross-functional teams to ensure high-quality, secure deployments. My deep understanding of Linux systems and GitOps principles aligns perfectly with the requirements of this role, and I am eager to bring my technical expertise to a globally distributed team. I am particularly drawn to Canonical's mission of simplifying open-source application deployment and its commitment to long-term security. I am confident that my skills in mentoring junior engineers, engaging with communities, and delivering timely, high-quality software make me a strong fit for this position. Thank you for considering my application. I look forward to the possibility of contributing to the innovative work at Canonical. Sincerely, Your Name Copy Sample interview questionsDescribe your experience with building and maintaining container images. What best practices do you follow for security and performance?I have extensive experience building Docker images for production environments, using multi-stage builds to minimize size, and scanning images for vulnerabilities with tools like Trivy. I follow practices like using minimal base images, pinning versions, and running as non-root users to enhance security. For performance, I optimize layer caching and ensure the image is built with the right CPU architecture. How would you design a CI/CD pipeline for automatically building and publishing container images to multiple registries? I would utilize a pipeline tool like GitHub Actions or Jenkins, with a matrix strategy to build for multiple architectures. The pipeline would include stages for linting, unit tests, building images, security scanning, and then publishing to registries like Docker Hub and Canonical's own registry. I would use GitOps principles, keeping pipeline config as code, and implement automated versioning with tag triggers for releases. Explain GitOps principles and how you would apply them to manage infrastructure and container image deployments. GitOps uses a Git repository as the single source of truth. For container images, I would store Kubernetes manifests or Helm charts in a repo, and use a tool like ArgoCD to sync the cluster state to the desired state in Git. This approach provides version control, audit trails, and easy rollbacks. Any changes to image versions would be done via pull requests, ensuring consistency. Given a new Python tool that needs to be containerized, how would you ensure it is secure, efficient, and well-documented? I would start with a slim base image, install only necessary dependencies, and create a non-root user. I'd add HEALTHCHECK instructions, use environment variables for configuration, and write a detailed Dockerfile with comments. For documentation, I would provide a README with usage examples, build instructions, and security notes. I would also set up automated builds and vulnerability scanning. How do you handle working in a globally distributed team and communicating technical decisions effectively? I rely on clear, asynchronous communication using tools like Slack, email, and documented RFCs. For complex topics, I write clear design documents and use diagrams when needed. I'm comfortable participating in video calls and pair programming sessions, and I always document decisions in a shared repository to ensure transparency and alignment.
