• Ensure version-controlled, auditable, and recoverable infrastructure changes
• Drive the transition from manual, imperative operations to declarative, desired-state automation
2. OpenShift Migration
• Lead and execute the migration of OpenShift workloads from VMware VMs to bare metal servers
• Ensure minimal downtime during migration and adherence to enterprise security standards
• Collaborate with application and platform teams to ensure migration success
3. Bare Metal Cluster Engineering
• Architect and optimize bare metal OpenShift clusters for performance, scalability, and resilience

• Administer, harden, and secure enterprise-grade Linux systems (RHEL preferred)
• Implement automated patching, configuration management, and compliance checks
• Troubleshoot OS-level and infrastructure-related issues
5. Networking & Oracle Integration
• Automate network configurations for bare metal environments (VLANs, routing, DNS)
• Support Oracle database deployments within Linux and OpenShift environments
• Work closely with network and database teams to ensure seamless integration
