• DevOps Mindset: Solid experience with CI/CD principles and tools (e.g., Jenkins, Tekton), and version control with Git. Experience with containerization and orchestration (Docker, Kubernetes, OpenShift) is essential.
• Strong Communication: Excellent verbal and written communication skills, with the ability to articulate complex technical concepts to both technical and non-technical audiences.
