Your responsibilities

The IT Web and Authoring section of the IT-PW group provides services for CERN's project collaboration, as well as software development tools for version control such as GitLab.

You are a SRE / DevOps Engineer interested in contributing to the enhancement of the CERN GitLab infrastructure.

By joining us, you will:

• Ensure the smooth operation, maintenance, and continuous evolution of the service.
• Design, implement, and manage complex CI/CD pipelines within GitLab, including Runners, DAST/SAST, dependency scanning, container registries, and environment management.
• Develop and maintain automation scripts (e.g., Python, Bash) to streamline software builds, testing, deployments, and infrastructure provisioning.
• Work with IaC (Infrastructure as Code) tools (e.g., Terraform / OpenTofu) to manage and provision on-premise cloud infrastructures.
• Integrate and configure monitoring, logging, and alerting solutions (e.g., Prometheus, Grafana, ELK Stack) to ensure environments health and performance.
• Identify areas for improvement and desirable new functionality with the GitLab user community.
• Further integrate GitLab with the CERN computing environment, driving DevSecOps adoption and incorporating CERN Security Team's recommendations to integrate security initiatives at every stage of the SDLC (software development lifecyle).
• Collaborate closely with development teams, providing support to integrate their applications with CI/CD pipelines, actively listening to their needs, troubleshooting issues, and providing clear, expert guidance on GitLab best practices to ensure a great user experience.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
