• 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

Skills:

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

• 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)
