• Develop and execute automation scripts and playbooks using Ansible and Ansible Automation Platform to automate repetitive administrative tasks, configuration management, deployments, and system maintenance on OpenShift and Linux environments.
• Support end users and application teams by resolving daily operational issues related to OpenShift and Linux systems, providing guidance, and ensuring smooth access and functionality.
• Document system configurations, operational procedures, runbooks, and troubleshooting guides with clear, detailed written communication to facilitate team knowledge sharing and compliance.
• Implement and support Infrastructure as Code (IaC) practices using tools like Terraform for consistent provisioning and configuration management.
• Utilize GitOps workflows and tools such as GitLab for version-controlled infrastructure changes, collaborative deployments, and pipeline automation.
• Maintain system performance and health, respond to alerts and incidents, conduct root cause analysis, and apply fixes to maintain reliability, security, and compliance in regulated environments.
• Collaborate with developers, DevOps teams, and stakeholders to integrate OpenShift support with application deployments and resolve cross-team operational challenges.
