About the Role :

We are seeking an experienced Senior Network Engineer specializing in Wireless networking to design, implement, and manage enterprise-grade Wi-Fi solutions. The role requires deep expertise in wireless technologies, RF design, security, troubleshooting, and optimization across large-scale environments.

Key Responsibilities :

- Wireless Network Design & Architecture : Design and deploy enterprise wireless networks (campus, branch, and large-scale environments). Conduct RF planning, site surveys, and capacity analysis using tools like Ekahau, AirMagnet, and similar. Define wireless architecture standards, best practices, and design frameworks.

- Wireless Implementation : Configure and manage wireless controllers and access points (Cisco, Aruba, Juniper Mist, Ruckus, etc.). Implement SSIDs, VLAN mappings, mobility groups, and roaming configurations. Ensure high availability and seamless roaming across wireless environments.

- Wireless Security : Design and implement secure wireless solutions (WPA3, 802.1X, EAP protocols). Integrate wireless networks with NAC solutions (Cisco ISE, Aruba ClearPass). Monitor for rogue APs, unauthorized access, and wireless threats.

- RF Optimization & Troubleshooting : Analyse RF performance, interference, coverage gaps, and client experience. Troubleshoot complex wireless issues such as latency, packet loss, roaming delays. Perform spectrum analysis and continuous optimization.

- Monitoring & Performance Management : Use monitoring tools (Cisco Meraki/Prime/DNA Center, Aruba Central/AirWave, Mist Cloud) to track performance. Implement QoS policies for voice/video over Wi-Fi. Drive improvements in user experience and network reliability.

- Cloud & Modern Wireless : Work with cloud-managed wireless platforms (Meraki, Mist, Aruba Central). Support hybrid integration with enterprise and cloud networks. Stay updated on Wi-Fi 6 / Wi-Fi 6E / Wi-Fi 7 technologies.

- Automation & Innovation : Develop automation scripts and workflows for wireless provisioning and monitoring. Leverage APIs and tools (Python, Ansible, Terraform) for configuration management. Drive continuous improvement initiatives.

- Incident & Change Management : Provide L3/L4 support for major wireless incidents. Lead root cause analysis and problem management. Support change implementation with risk assessment and rollback planning.

- Documentation & Governance : Maintain detailed documentation (designs, runbooks, SOPs). Ensure compliance with enterprise security and governance policies. Support audits and regulatory requirements.

Required Skills & Qualifications :

- Bachelors degree in computer science, IT, or related field.

- 36 years of experience in networking, with strong focus on wireless.

- Hands-on expertise with enterprise wireless platforms (Cisco, Aruba, Mist, Ruckus), RF fundamentals (channel planning, power levels, interference mitigation), and wireless protocols (802.11 a/b/g/n/ac/ax - Wi-Fi 6/6E/7).

- Strong knowledge of TCP/IP networking and network integration (R&S fundamentals), authentication protocols (802.1X, RADIUS, EAP), and high-density wireless design.
