Docker - Senior Supply Chain Security Engineer

• This is not a traditional software engineering role. You'll spend most of your time working with YAML definition files, upstream OSS projects, and the container and Kubernetes ecosystems - packaging and adapting software rather than building it from scratch. If you've ever maintained packages for a Linux distribution, contributed to a Helm chart upstream, or worked as a platform/infrastructure engineer with a strong security lean, this will feel familiar. • 6+ years of backend engineering experience with production-grade systems • Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience • Strong familiarity with the container and Kubernetes ecosystem - you know what cert-manager, kyverno, grafana, and istio are, you've deployed them, and you can read upstream Helm chart source without getting lost • Comfort with YAML as a primary working medium - you think carefully about structure, conventions, and patterns • Understanding of container security basics - non-root users, UID/GID, image layers, multi-arch builds, supply chain concepts • Some Go ability - enough to read and write test code, not to build distributed systems • A maintainer mindset - you take pride in consistency, catch drift from patterns, and think about how your change affects others downstream • Familiarity with GitHub-heavy open source workflows - PRs, upstream tracking, monorepo conventions • Experience as a package maintainer (any Linux distribution, Homebrew, etc.) • Helm chart authorship or contribution experience • Familiarity with supply chain tooling (Sigstore, SBOM, SLSA) • Experience in a regulated or security-conscious environment • Docker considers sponsorship on a case-by-case basis based on business needs.
