Job description

As an experienced DevOps Engineer you will evolve a Jenkins Shared Library powering complex, multi-language builds (Java/Maven, Node/NPM, Python, Helm, Terraform, containers). This is a hands-on, high-impact contract focused on modernizing infrastructure. Your primary mission is to engineer fast, secure pipelines (SLSA, SBOM, digests) and strictly enforce supply-chain integrity.

Core Responsibilities:

Pipeline Architecture: Design and maintain Groovy pipeline steps covering the entire build, test, scan, and deploy life cycle
Security Automation: Extend Python tooling for SLSA provenance, SBOM generation, and automated security scan aggregation (SonarQube, Sonatype IQ, SAST)
Aggressive Optimization: Maximize pipeline performance through parallel builds, caching, and dependency prefetching
Artifact Integrity: Ensure strict cryptographic integrity, reproducible inputs, and correct SHA1/SHA256 mapping
Modernization: Refactor Legacy scripts by removing global state and standardizing templates

Requirements

6+ years in devops/platform/software engineering roles
3+ years in CI/CD platform engineering or DevSecOps
High skill in Jenkins/Groovy/Tekton, ideally with experience in Shared Libraries
Deep Python Scripting experience and automation
Able to work on complex YAML/JSON processing and automation
Modern DevSecOps knowledge including continuous artifact integrity, multi-language packaging and cutting-edge supply-chain security frameworks (SLSA, CycloneDX SBOM)
Track record of performance tuning
Strong ownership mindset
