Lead as the service owner for network tools, accountable for design, deployment, operations, and lifecycle management.
Drive proof-of-concepts, vendor evaluations, and roadmap alignment to ensure tools deliver enterprise value.
Architect and oversee migrations of network tools and services from on-premises to cloud-native environments.
Embed automation-first practices into service design, operations, administration, and user access.
Strengthen security controls across tools, including RBAC, patching, OS lifecycle management, and vulnerability remediation.
