That trust rests on our commitment to hardened, production-ready images.\nWe are advancing the state of the art with a new generation of Ubuntu-based container images we call \"rocks\": minimal images engineered for performance and usability and backed by long-term security commitments. As a member of the team, you will own the path from upstream source to published image, turning open source software into tested, signed, and continuously maintained artifacts that developers can deploy with confidence.\nThis is fast-paced, multi-disciplinary software engineering. Because most of the software we package originates from third-party upstreams, you will work across a broad range of container technologies and hundreds of open source projects, often in several programming languages, integrating and maintaining them so they are easy to consume on Ubuntu. Automation is central to the role: you will build the pipelines that package, build, test, and publish images at scale.\nYour seniority in this role will reflect your software engineering experience and your ability to mentor and guide more junior colleagues.\nLocation: This is a globally remote role\nThis role entails\nBuild and maintain a growing portfolio of high-quality, hardened container images\nDesign and operate automated CI/CD pipelines that build, test, scan, sign, publish, promote, and retire images across environments and architectures\nWrite tooling and tests to assess security compliance and cloud-native compatibility\nWork closely with the community and partners to share container expertise and keep our portfolio current with new features, patches, and applications\nCollaborate with our product security, platform, infrastructure, and customer-facing teams\nContribute technical input to the team's decision-making\nSet the standard for quality, defining image standards that span security, compatibility, performance, size, and developer experience\nGrow our knowledge base and write about the work we do\nWork in a collaborative, agile, and globally distributed environment\nMentor colleagues and contribute to hiring\nWork from home with global travel of up to 15% for internal and external events\nWhat we are looking for in you\nProficiency in Bash and Python\nExperience working with CI/CD systems (e.g. GitHub Actions, Jenkins)\nExperience building container images\nCommand of at least one container management or orchestration tool (e.g. Docker, Podman, or Kubernetes)\nHands-on experience with Linux systems, package management, build systems, release engineering, or artifact pipelines\nClear communication and end-to-end ownership, spanning design, review, documentation, operation, and cross-team collaboration\nA commitment to sharing knowledge and helping those around you grow\nA genuine appetite for learning and for working outside your comfort zone\nA Bachelor's degree or equivalent in Computer Science, a STEM field, or a similar discipline\nAn exceptional academic track record from both high school and university\nBusiness level written and spoken English.\nSincere personal motivation aligned with our mission.\nInternational travel 2-4 times a year for company events up to two weeks long.\n0-7 years relevant experience.\nIn addition we expect that you will match our values, by being:\nPrecise, taking care to deliver correctness and clarity.\nReliable, delivering high quality work that builds trust and confidence.\nAccessible, collaborating to build products and systems that are usable.\nAdroit, blending enthusiasm, knowledge, adaptability, style and character.\nNice-to-have skills\nA security-oriented maintenance mindset: you can investigate dependency and vulnerability findings, assess their impact, and deliver a safe fix\nAn understanding of software supply chain security, with some experience generating and consuming artifacts such as SBOMs, signatures, provenance, or CVE reports\nFamiliarity with GitOps principles and workflows\nFamiliarity with additional languages such as Go or Rust\nHands-on experience building minimal and distroless container images\nKnowledge of the OCI specifications\nFamiliarity with security or compliance frameworks such as CIS, NIST, FedRAMP, or DISA STIG\nEvidence of contributions to open source projects\nA passion for embedding security across all stages of the engineering lifecycle (DevSecOps), and an interest in using AI or agentic development responsibly and safely\nRelevant Linux, container, or cloud-native certifications (such as CKS or DCA) are welcome\nIf your experience is close but does not match every requirement, we encourage you to apply. We value transferable experience from Linux packaging, release engineering, build systems, platform engineering, and open-source maintenance.\nWhat we offer colleagues\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 recognize 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.\nDistributed work environment with twice-yearly team sprints in person\nPersonal learning and development budget of USD 2,000 per year\nBi-annual compensation review\nCompany recognition rewards\n40 days annual leave per annum, including public holidays and our All Company holiday periods\nMaternity and paternity leave\nTeam Member Assistance Program & Wellness Platform\nOpportunity to travel to new locations to meet colleagues, with Priority Pass for lounge access\nAbout Canonical\nCanonical is a pioneering tech firm at the forefront of the global move to open source.
