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
Triaging CVEs and contributing 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
