Responsibilities

• Optimize System Control → Ensure the stable operation of central systems (z/OS), subsystems, and server infrastructures (Linux, Unix, Windows), using Grafana, Prometheus, OpenSearch, and automated CLI scripts for monitoring, log analysis, and secrets/certificates management.
• Enhance Application Monitoring → Oversee and improve monitoring for distributed applications, working with Docker-based environments and (ideally) Kubernetes/OpenShift to maintain consistent performance across platforms.
• Streamline Event Management → Manage event processing end-to-end, coordinating deployments and handling application-specific configuration updates to ensure smooth, interruption-free operations.
• Resolve Complex Issues → Take ownership of escalated 2nd/3rd-level issues—ranging from certificate management and memory leaks to database and firewall connectivity problems—restoring system stability efficiently.
• Strengthen Incident Recovery → Lead incident recovery efforts by ensuring rapid service restoration, structured deployment execution, and clear, consistent operational documentation.
• Implement Process Improvements → Drive continuous improvement by implementing standardized changes, supporting emergency drills, collaborating with internal client teams, and optimizing CI/CD processes.
