Задачи

• 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
• This 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
• Build and maintain a growing portfolio of high-quality, hardened container images
• Design and operate automated CI/CD pipelines that build, test, scan, sign, publish, promote, and retire images across environments and architectures
• Write tooling and tests to assess security compliance and cloud-native compatibility
• Collaborate with our product security, platform, infrastructure, and customer-facing teams
• Contribute technical input to the team's decision-making
• Set the standard for quality, defining image standards that span security, compatibility, performance, size, and developer experience
• Grow our knowledge base and write about the work we do
• Work in a collaborative, agile, and globally distributed environment
• Mentor colleagues and contribute to hiring
• In addition we expect that you will match our values, by being
• Precise, taking care to deliver correctness and clarity
• Reliable, delivering high quality work that builds trust and confidence
• Accessible, collaborating to build products and systems that are usable
• Adroit, blending enthusiasm, knowledge, adaptability, style and character
• Nice-to-have skills
• A security-oriented maintenance mindset: you can investigate dependency and vulnerability findings, assess their impact, and deliver a safe fix

• Experience working with CI/CD systems (e.g. GitHub Actions, Jenkins)
• Experience building container images
• Command of at least one container management or orchestration tool (e.g. Docker, Podman, or Kubernetes)
• Hands-on experience with Linux systems, package management, build systems, release engineering, or artifact pipelines
• Clear communication and end-to-end ownership, spanning design, review, documentation, operation, and cross-team collaboration
• A commitment to sharing knowledge and helping those around you grow
• A genuine appetite for learning and for working outside your comfort zone
• A Bachelor's degree or equivalent in Computer Science, a STEM field, or a similar discipline
• An exceptional academic track record from both high school and university
• Business level written and spoken English
• 0-7 years relevant experience
• An understanding of software supply chain security, with some experience generating and consuming artifacts such as SBOMs, signatures, provenance, or CVE reports
• Familiarity with GitOps principles and workflows
• Familiarity with additional languages such as Go or Rust
• Hands-on experience building minimal and distroless container images
• Knowledge of the OCI specifications
• Familiarity with security or compliance frameworks such as CIS, NIST, FedRAMP, or DISA STIG
• Evidence of contributions to open source projects
• A passion for embedding security across all stages of the engineering lifecycle (DevSecOps), and an interest in using AI or agentic development responsibly and safely
• Relevant Linux, container, or cloud-native certifications (such as CKS or DCA) are welcome
• We value transferable experience from Linux packaging, release engineering, build systems, platform engineering, and open-source maintenance
