Qualifications

• Expert Jenkins internals: declarative and scripted pipelines, shared libraries, multibranch, trigger graphs — and Bitbucket Server administration.
• Enterprise CI/CD architecture: promotion models, environment strategy, secrets management, policy-as-code.
• GHAS or equivalent AppSec tooling integration; IaC (Terraform) for platform provisioning.
• Strong written design skills — ADRs, standards, runbooks that survive handover.

Responsibilities

• Author and version the golden-path reusable GitHub Actions workflows per archetype, consumed by reference with drift detection.
• Design the self-hosted runner topology (residency-aware) and integrate enterprise tooling: GHAS, Snyk/Sonar, Vault/CyberArk, Artifactory.
• Define the Jenkins→Actions conversion standards: secrets re-binding, shared-library equivalence, trigger mapping, artefact handling.
• Act as design authority on bespoke long-tail pipelines and review agent-generated PRs for architectural soundness.
• Partner with client platform/security teams; prepare the platform handover to client BAU.
