At Mindbox we connect top IT talents with technology projects for leading enterprises across Europe.
Are you passionate about secure, high-performance CI/CD systems and cutting-edge DevSecOps practices? We are looking for a DevSecOps Engineer to own and evolve our Jenkins Shared Library, which powers multi-language builds including Java/Maven, Node/NPM, Python, Helm, Terraform, and container images.
Your work will strengthen supply-chain integrity, deliver secure, provenance-rich pipelines (SLSA, SBOM, digests), and ensure a seamless developer experience across teams.
Sounds like your kind of challenge?

- Optimize pipeline performance (parallel builds, caching, reduced BOM scope, dependency prefetch).
- Guarantee artifact integrity through SHA1/SHA256 mapping and evidence modeling.
- Refactor legacy scripts for maintainability and standardization.
- Document ci-config.yaml patterns and enforce best practices.
- Mentor engineers on secure pipeline development and compliance practices.
