About The Position

Position requires extensive knowledge of the telecommunication industry, network architectures, engineering and deployment support for Vendor provided transport services and integration into the data network. The client is looking for a Network Engineer responsible for the design, governance, and continuous evolution of enterprise network architecture across LAN, WAN, SD-WAN, wireless, firewall, load-balancing, and network security domains. The Network Architect shall: Serve as the technical authority for all network architecture decisions, including routing, segmentation, firewall architecture, load-balancing architecture, security integration, traffic engineering, and resiliency design. Develop, maintain, and continuously refine network architecture artifacts, including: High-level and low-level network designs (HLDs/LLDs) Network segmentation models supporting IT/OT convergence Routing architectures (BGP, OSPF, SD-WAN) and failover design Firewall security zone models and policy framework architecture Load-balancing and application delivery architecture designs Define and enforce network standards and configuration baselines to ensure consistency, security, availability, performance, and operational supportability across all environments. Establish architecture standards for firewalls, VPNs, ADC/load-balancing platforms, network segmentation, high-availability services, and cloud connectivity. Support lifecycle and capacity planning, including: Hardware/software EOL/EOS tracking Throughput forecasting and scalability planning Network modernization roadmap development Firewall and load-balancer lifecycle planning Coordinate network architecture alignment with NFE Solution implementation and enterprise infrastructure environments. Review and approve firewall segmentation strategies, security zone designs, routing architectures, application traffic flows, and load-balancing configurations to ensure alignment with enterprise architecture standards. Support CCB activities by reviewing and approving all network-related changes impacting architecture, security, availability, performance, or resiliency. Evaluate and incorporate OEM/vendor solutions and industry best practices for routing, switching, wireless infrastructure, firewalls, load balancing, network security, and cloud networking into the enterprise network environment. Provide architectural oversight for integration of monitoring, telemetry, observability, and network management platforms to ensure operational visibility and supportability of all network services.
