About the role

  • Senior Supply Chain Security Engineer developing Docker's security-hardened images and managing Helm charts. Collaborating on upstream OSS projects and ensuring compatibility with Kubernetes and security guidelines.

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

Requirements

  • 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

Benefits

  • Freedom & flexibility; fit your work around your life
  • Designated quarterly Whaleness Days plus end of year Whaleness break
  • Home office setup; we want you comfortable while you work
  • 16 weeks of paid Parental leave (after 6 months of employment)
  • Technology stipend equivalent to $100 USD net/month
  • PTO plan that encourages you to take time to do the things you enjoy
  • Training stipend for conferences, courses and classes
  • Equity; we are a growing start-up and want all employees to have a share in the success of the company
  • Docker Swag
  • Medical benefits, retirement and holidays vary by country
  • Remote-first culture, with offices in Seattle and Paris
