Our client in the Information Technology and Services industry is looking for a DevOps Engineer / Build Pipeline Engineer to own and evolve a Jenkins Shared Library powering multi-language builds across Java/Maven, Node/NPM, Python, Helm, Terraform, and container technologies. The successful candidate will deliver fast, secure, provenance-rich pipelines using SLSA, SBOMs, and artifact digests while strengthening software supply chain integrity across engineering teams.

What you will do:

• Design and maintain Groovy pipeline steps covering build, test, package, scan, and deployment activities.
• Extend Python tooling for SLSA provenance, SBOM generation, hash and digest accuracy, and security scan aggregation.
• Integrate and maintain security scanning capabilities across SonarQube, Sonatype IQ, SAST, and container scanning.
• Optimise pipeline performance through parallel builds, caching, dependency prefetching, and scope-reduced BOMs.
• Ensure artifact integrity through accurate SHA1/SHA256 mapping, reproducible inputs, and evidence modelling.
• Refactor legacy scripts by removing global state, consolidating hashing, and standardising pipeline templates.
• Document ci-config.yaml standards, configuration requirements, and usage patterns.
• Mentor engineers on secure pipeline development and software supply chain practices.
• Troubleshoot pipeline incidents and implement improvements to prevent recurring issues.
• Assess the current shared library structure and understand supported building blocks and modules.
• Investigate user-reported issues to develop a strong understanding of critical pipeline components and configuration options.
• Identify and classify pipeline bugs and develop appropriate hot fixes.
• Deliver at least two small pipeline features or improvements during the initial 30-day period.
• Apply secure and compliant CI/CD practices across engineering environments.

Qualifications

• Bring 7+ years of software engineering experience, including at least 3 years working with CI/CD platforms or DevSecOps.
• Demonstrate strong Jenkins and Groovy Shared Library expertise.
• Demonstrate advanced Python automation skills, including JSON/YAML processing and tooling development.
• Bring deep knowledge of Maven, NPM, and Python packaging, with exposure to Helm, Terraform, and container image metadata.
• Demonstrate strong understanding of software supply chain security practices, including SLSA, CycloneDX SBOMs, and artifact digests.
• Bring hands-on experience with SonarQube, Sonatype IQ, container scanning, and SAST solutions.
• Demonstrate proven experience optimising pipeline performance through caching, parallelisation, dependency pruning, and similar techniques.
• Demonstrate awareness of security, compliance, and software supply chain requirements.
• Bring experience with artifact signing and attestations using technologies such as cosign and OCI as an advantage.
• Demonstrate experience publishing Terraform modules and Helm charts as an advantage.
• Bring GitOps or release automation experience as an advantage.
• Demonstrate GCP or AWS cloud experience as an advantage.
• Demonstrate relevant Python and Jenkins/Tekton experience through previous engineering projects.
• Demonstrate precise communication and strong documentation discipline.
• Demonstrate an ownership mindset and the ability to operate effectively with minimal supervision.
