Core Responsibilities

Primary Functions

Design and develop scalable enterprise WLAN architectures using best practices for controller-based and cloud-managed solutions (Cisco, Aruba, Ruckus, Meraki), documenting topology diagrams, capacity estimates, and redundancy models.
Lead and perform RF site surveys and heat‑map generation (Ekahau, AirMagnet, NetAlly), including pre‑survey planning, on‑site spectrum analysis, and post‑survey channel/power recommendations to achieve coverage and capacity objectives.
Conduct spectrum analysis to identify and mitigate sources of RF interference (Bluetooth, microwave, IoT devices), producing actionable remediation plans and vendor escalation when required.
Configure, deploy, and maintain access points, wireless LAN controllers, mobility controllers, and bridges; manage firmware upgrades, patches, and staged rollouts to minimize risk and downtime.
Implement and manage enterprise wireless security controls including 802.1X authentication, RADIUS server integration, WPA2/WPA3 policies, guest portals, BYOD onboarding (MAB/Simple Captive Portal), and NAC workflows.
Troubleshoot complex wireless incidents using packet captures, controller logs, AP debug, and client-side diagnostics to identify root causes for roaming failures, authentication issues, high retry rates, and throughput anomalies.
Optimize network performance through channel planning, transmit power tuning, client load balancing, band steering, and airtime fairness policies to improve user experience for high-density and voice-over-Wi‑Fi deployments.
Plan and execute capacity forecasting and growth planning for densely populated environments (auditoriums, stadiums, classrooms), aligning AP counts and backhaul capacity with business events and seasonal demand.
Integrate WLAN with core network services — VLANs, DHCP, DNS, firewalls, QoS policies, multicast routing — to ensure consistent user experience and voice/video performance over Wi‑Fi.
Manage and administer wireless monitoring and analytics platforms (controller dashboards, Aruba Airwave, Cisco DNA Center, Meraki Dashboard), creating operational dashboards, alerts, and SLA reports for latency, packet loss, and client health.
Define and maintain WLAN standard operating procedures, runbooks, architecture documentation, and configuration baselines to ensure consistent deployment and faster incident resolution.
Lead wireless rollout projects from requirements gathering through pilot, site validation, and production cutover — coordinate cabling, power, ceiling mounts, PoE provisioning, and facilities access.
Collaborate with security, applications, and infrastructure teams to perform vulnerability assessments, penetration testing, and remediate wireless-specific risks including rogue AP detection and guest isolation.
Support location services and location-based systems (BLE beacons, Wi‑Fi RTT, Cisco CMX) including calibration, mapping, and integration with asset tracking or analytics platforms.
Provide subject matter expertise for wireless design inputs into new construction and renovation projects; review blueprints, conduit and AP placement, and ensure DAS/Wi‑Fi coexistence planning.
Maintain wireless inventory and lifecycle management — asset tagging, warranty tracking, spare AP management, and vendor RMA coordination to reduce MTTR.
Automate routine WLAN tasks and reporting using scripting (Python, PowerShell) and configuration management tools (Ansible) to accelerate deployments and enforce configuration hygiene.
Deliver end-user and operational training, knowledge transfer sessions, and escalated support for NOC/Help Desk on wireless troubleshooting best practices and triage flows.
Enforce compliance with industry standards and regulatory requirements (FCC rules, RF exposure limits), ensuring safe and legal wireless power settings and channel usage.
Conduct post-incident reviews and continuous improvement exercises after major outages or performance degradation events; implement remediation and preventive controls.
Serve as primary point of contact for wireless vendor support and professional services, evaluating vendor solutions, negotiating support contracts, and coordinating multi-vendor interoperability testing.
Participate in wireless proof-of-concept evaluations and pilot programs for emerging technologies (Wi‑Fi 6/6E/7, private LTE/5G, CBRS), assessing readiness and operational impact before enterprise rollout.
Monitor and manage roaming and authentication performance for mobile device fleets, retail POS systems, and voice handsets, tuning session timeouts and stateful roaming parameters.
Prepare and present wireless capacity plans, architecture proposals, and technical status reports to technical leadership and business stakeholders to align investments with business priorities.

Secondary Functions

Maintain and update wireless knowledge base articles, deployment checklists, and incident escalation matrices for cross-team visibility.
Support field technicians with complex on-site troubleshooting, providing remote diagnostics, configuration snapshots, and escalation recommendations.
Contribute to procurement specifications and RFQ responses, creating technical requirement lists, acceptance test plans, and evaluation criteria for AP and controller purchases.
Assist in development of test labs and sandboxes to validate firmware, feature upgrades, and interoperability with controller and security platforms prior to production deployment.
Track wireless performance KPIs and deliver monthly executive summaries with actionable insights and capacity recommendations.
Mentor junior network engineers and participate in recruiting and interview evaluations for wireless engineering positions.
