Roles & Responsibilities:

• Site Network Assessment Conduct detailed assessment of the existing power plant network infrastructure.
• Review routers| switches| firewalls| WAN connectivity| wireless infrastructure| network circuits| racks| patch panels| and physical cabling.
• Document the current-state network topology and identify technical gaps| risks| dependencies| and obsolete infrastructure.
• Target Network Architecture Design the target-state network architecture required to integrate the power plant into the enterprise environment.
• Develop HLD/LLD| network topology diagrams| connectivity requirements| IP addressing strategy| segmentation| redundancy| and resiliency requirements.
• LAN/WAN Architecture Design and validate enterprise LAN/WAN connectivity| including routing| switching| VLANs| WAN circuits| SD-WAN| and site connectivity.
• Define redundant connectivity and high-availability requirements for critical plant services.
• Network Security & Segmentation Work with cybersecurity and OT security teams to develop secure network segmentation between enterprise IT and plant/OT environments.
• Support firewall architecture| security zones| access requirements| and network-security controls.
• Ensure the migration adheres to applicable client security and infrastructure standards.
• OT/IT Integration Coordinate integration requirements between corporate IT infrastructure and power plant operational technology.
• Identify connectivity dependencies involving plant systems and other operational applications without introducing unnecessary dependencies between OT and enterprise networks.
• Site Migration Planning Develop the detailed network migration and cutover approach.
• Identify prerequisites| sequencing| dependencies| maintenance-window requirements| validation criteria| rollback requirements| and post-migration activities.
• Design the migration to minimize interruption to site operations
• .Physical Infrastructure & Cabling Assess structured cabling and physical network infrastructure.
• Identify requirements for fiber/copper cabling| patch panels| racks| network closets| equipment installation| labeling| and connectivity.
• Coordinate with field-services and cabling teams during implementation.
• Network Equipment & Configuration Design Define requirements
