• Strong knowledge of CI/CD tools (like CircleCI, Jenkins, GitHub Actions, GitLab CI).
• Experience with Infrastructure as Code (like Terraform, Pulumi, Ansible).
• Excellent communication skills and a collaborative mindset.
• Excellence as a remote contributor, managing time and communication with intention, staying connected to the team, and delivering results reliably
