- • Communicate with stakeholders to capture network requirements and constraints.
- • Provide guidance on network design options, costs, and change impacts.
- • Document network architectures, diagrams, configurations, and installation procedures.
- • Verify interoperability, performance, scalability, and security of network designs.
- • Collaborate with systems, security, and vendor teams to ensure component compatibility.
- • Evaluate emerging networking technologies (e.g., SD-WAN, Wi-Fi, cloud networking) for fit and cost.
- • Provide escalation support for complex network incidents and problems.
- • Identify required routers, switches, firewalls, cabling, IP addressing, and management tools.
- • Define and publish guidelines for secure network deployments and segmentation.
- • Monitor network health and capacity using NMS, SNMP/telemetry, and logs.
- • Lead the design, deployment, and operation of campus, data center, and WAN networks.
- • Assess vendor products and make recommendations on hardware, software, and services.
- • Perform routine maintenance, firmware/OS upgrades, and configuration backups.
- • Configure routers, switches, firewalls, VPNs, load balancers, and wireless controllers.
- • Develop and manage network project plans, timelines, and budgets.
- • Analyze business objectives to determine network scope, risks, and organizational impact.
- • Develop LAN/WAN/WLAN, data center, and cloud network architectures and integration patterns.
- • Design and execute failover, throughput, and latency tests and validations.
- • Establish network standards for IP addressing, VLANs, routing, QoS, and security controls.
- • Review existing network performance and propose upgrades or optimizations.
- • Test and validate firmware, security patches, and configuration changes before production.
- • Communicate project status and technical findings via reports and presentations.
- • Model traffic and capacity, using labs or simulations, to predict performance under load.
- • Direct installation of network equipment, cabling, and wireless access points.
- • Train IT staff on network operations, tools, and best practices.
