• Experience with secure CI/CD pipelines in Azure DevOps or GitHub Actions, including container and dependency vulnerability scanning

What's in It for You

€2,100 – €3,000 Gross / Month depending on experience, alongside a fully on-site working setup based in Marousi (Athens) or Patras, ticket restaurant vouchers to support daily expenses, and comprehensive private health insurance coverage.
