What you'll do

  • Design, build, and maintain secure CI/CD pipelines with security gates that catch issues before they reach production.
  • Systematically, consistently and automatically capture the risk exposure of Chainguards products.
  • Implement and enforce software supply chain security controls: signed artifacts, SBOMs, provenance attestation (SLSA, Sigstore / Cosign).
  • Proactively identify emerging customer security needs, and build solutions to meet these.
  • Lead security architecture reviews and threat models for Kubernetes-based workloads running on GCP and AWS.
  • Harden container images, Kubernetes cluster configurations, and cloud IAM postures — minimising attack surface across our product stack.
  • Define and drive adoption of baseline security standards: pod security standards, network policies, workload identity, secrets management.
  • Evaluate and operationalise CNAPP / CSPM tooling to maintain continuous visibility into cloud-native risk.

What they require

  • 7+ years in software engineering, security engineering, or a combined role with meaningful hands-on security responsibility throughout.
  • Strong proficiency in Go or Python, with the ability to write, review, and debug production-quality code.
  • Deep, hands-on experience with Kubernetes in production (cluster hardening, RBAC, network policies, admission controllers).
  • Practical expertise with GCP and/or AWS: IAM, workload identity, secrets management, security services (e.g., GCP Security Command Center, AWS Security Hub).
  • Proven track record designing and securing CI/CD pipelines (GitHub Actions, Cloud Build, Tekton, or similar).
  • Fluency with container security: image scanning, distroless/minimal base images, runtime security.
  • Experience with software supply chain security tooling and frameworks (Sigstore, SLSA, SBOM generation).
  • Solid understanding of OWASP, NIST, and cloud security frameworks and how to apply them pragmatically.
  • Preferred: Familiarity with Chainguard Images or other minimal/hardened container base image ecosystems.
  • Preferred: Contributions to open source security projects.
  • Preferred: Background in security research or offensive security (bug bounty, CTF, penetration testing).
