This is a hands-on role requiring an experienced technical lead who can independently work with stakeholders (Workplace/Facilities, Security, Network, IAM, Endpoints, Applications, and Service Desk) to gather requirements, develop HLD/LLD, execute deployments and migrations, and provide expert-level troubleshooting and operational support.

Key Responsibilities

1) Stakeholder Engagement & Requirements Discovery

. Independently engage business and IT stakeholders to collect wireless requirements across offices, campuses, warehouses, and critical environments.

. Define wireless outcomes for coverage, performance, capacity, resiliency, roaming, security, and guest/BYOD use cases.

. Lead design workshops and produce clear recommendations with options, tradeoffs, risks, and timelines.

. Coordinate cross-functional readiness (security policies, device onboarding, NAC integrations, change windows, operational support model).

2) Wireless Architecture, Design & Standards (HLD/LLD)

. Own enterprise wireless architecture and design for Cisco and Aruba environments including: Controller-based and/or distributed wireless designs (as per platform) SSID architecture (corporate, guest, IoT), RF design strategy, roaming design High availability, redundancy, controller/AP failover, and resilience patterns

. Develop High-Level Design (HLD), Low-Level Design (LLD), RF/coverage plans, cutover plans, and runbooks.

. Define and standardize: WLAN security (WPA2/WPA3 enterprise, 802.1X, PSK where appropriate) Authentication/authorization flows (RADIUS, SSO where applicable) Network segmentation (VLANs, roles, ACLs), QoS for voice/video Monitoring and logging standards (alerts, dashboards, health metrics)
