Senior Supply Chain Security Engineer

Responsibilities

• Authoring and maintaining image definition files that track upstream OSS project releases, define build steps, and keep our catalogue current across dozens of images
• Adapting upstream Helm charts (cert-manager, grafana, mongodb, kyverno, and many more) to work with DHI images - handling security constraints, non-root contexts, and Kubernetes compatibility concerns
• Tracking upstream version releases and semver patterns across monorepos and standard repos, handling major version breaks and dependency chains
• Writing Go-based integration tests that validate images and charts behave correctly in real Kubernetes environments
• Triage CVEs and contribute to security hardening decisions across images
• Reviewing peers' definitions and chart PRs against established conventions and catching subtle issues before they reach customers

Qualifications

• 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
• Bonus: 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
