Network SME

Key Responsibilities

1) Planning & Design

·       Lead discovery (inventories, site surveys, RF heatmaps, cabling readiness), current‑state assessment, and risk analysis.

·       Produce HLD/LLD for LAN/WLAN, routing, segmentation (VLANs/VRFs), and IP addressing; review with architecture/governance.

·       Define cutover strategies, rollback plans, test scripts, and acceptance criteria; coordinate maintenance windows and approvals.

·       Standardize device naming, management/OOB access, and configuration baselines; maintain firmware/patch schedules. (Device naming, OOB management, firmware maintenance recommendations.)

2) Implementation & Migration

·       Configure and deploy stacked access/distribution/core switches (VLANs, STP, LACP/Port‑Channel, QoS), routers (OSPF/BGP/EIGRP, NAT, ACLs, VRF), and WLC/APs (SSIDs, auth, RF tuning).

·       Execute site cutovers (brownfield/greenfield), validate routing/forwarding paths, wireless coverage, and application reachability.

·       Perform structured post‑migration testing (ping, traceroute, app transactions), fix defects, and stabilize performance. (Testing/validation and runbook‑based handover.)

·       Deliver common LAN/WLAN implementation tasks (e.g., add/remove SSIDs, AP moves, WLC upgrades, core device replacements) within cataloged change types.

3) Security, Access & Integration

·       Implement/operate 802.1X/RADINAC (e.g., Cisco ISE) policies for wired/wireless; integrate with AD/IdP.

·       Coordinate firewall rule updates and VPN tunneling to support application migrations; triage connectivity issues with security teams.

·       Align with LAN/WLAN design standards (e.g., stacked access switches, WLC redundancy, HA in core/distribution) and licensing prerequisites for automation/ZTP where applicable.

4) Operations, Handover & Governance

·       Own implementation documentation: updated network diagrams, IP addressing plans, device configuration archives, and operational runbooks; deliver formal handover.

·       Guide L2/L1 engineers; provide preventive maintenance routines and incident resolution leadership; ensure SLA compliance.

·       Use enterprise monitoring tools (e.g., SolarWinds, NNM) and automation for provisioning/compliance; recommend SDN/VXLAN/segmentation enhancements where relevant.

Required Skills & Experience

·       10+ years in enterprise networking with hands‑on migrations/implementations for switches/routers/WLC/APs.

·       Deep knowledge of L2/L3 protocols (STP/RSTP/MST, LACP, VLANs, OSPF/BGP/EIGRP, VRF), QoS, and wireless (WLC, RF design, WPA2/WPA3, 802.1X/RADIUS).

·       Experience with NAC (e.g., Cisco ISE), firewall policy alignment, and site‑to‑site/client VPN support during application moves.

·       Tooling: ServiceNow for change/tickets, SolarWinds/NNM for monitoring, and Ansible/Netmiko (or equivalent) for configuration automation.

·       Proven track record of cutover execution (brownfield & greenfield) with robust rollback/test plans and stakeholder communication.
