Description

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.

Your responsibilities:

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

Essential skills/knowledge/experience:

7+ years engineering; 3+ in CI/CD platform or DevSecOps.

Strong Jenkins + Groovy shared library expertise.

Advanced Python automation (JSON/YAML processing, tooling scripts).

Deep Maven/NPM/Python packaging knowledge; exposure to Helm/Terraform and container image metadata.

Supply-chain security (SLSA, CycloneDX SBOM, digests).

Experience with SonarQube, Sonatype IQ, container and SAST scanning.

Proven performance tuning (caching, parallelization, dependency pruning).

Compliance Awareness.

Desirable skills/knowledge/experience:

Artifact signing / attestations (cosign, OCI).
Terraform module and Helm chart publishing patterns.
GitOps or release automation experience.
GCP/AWS cloud experience
