Job description

Overview

Own and evolve our Jenkins Shared Library powering multi-language builds (Java/Maven, Node/NPM, Python, Helm, Terraform, containers). Deliver fast, secure, provenance-rich pipelines (SLSA, SBOM, digests) and strengthen supplychain integrity across teams.

Responsibilities

1. Design and maintain Groovy pipeline steps (build, test, package, scan, deploy).
2. Extend Python tooling for SLSA provenance, SBOM generation, hash/digest accuracy, and security scan aggregation (SonarQube, Sonatype IQ, SAST/Container).
3. Optimize performance (parallel builds, caching, scope-reduced BOMs, dependency prefetch).
4. Ensure artifact integrity (correct SHA1/SHA256 mapping, reproducible inputs, evidence modeling).
5. Refactor legacy scripts (remove global state, consolidate hashing, standardise templates).
6. Document ci-config.yaml standards and usage patterns.
7. Mentor engineers on secure pipeline development and supply-chain practices.
8. Troubleshoot and prevent pipeline incidents.
