Job Description

• Network Design and Implementation:
• Design, deploy, and manage wireless network solutions, including access points, controllers, and wireless LAN controllers (WLCs) to provide optimal coverage and performance.
• Configure and maintain Layer 2/3 network switching environments, including VLANs, STP, VTP, HSRP/VRRP, VSS, and port channel configurations.
• Implement and manage firewall solutions from vendors like Cisco, Palo Alto, Fortinet, and Check Point, including configuring access control lists (ACLs), NAT, VPNs, and intrusion prevention systems (IPS).
• Advanced Troubleshooting and Support:
• Act as an escalation point for L1 and L2 network support teams, providing advanced troubleshooting for wireless, switching, and firewall-related issues.
• Diagnose and resolve complex network issues such as connectivity problems, packet loss, latency, and security incidents.
• Use network monitoring tools and packet analyzers (e.g., Wireshark, SolarWinds, Cisco DNA Center) to identify and address performance bottlenecks and failures.
• Wireless Network Optimization:
• Conduct site surveys using tools like Ekahau or AirMagnet to design and optimize wireless coverage, capacity, and performance.
• Troubleshoot RF-related issues, such as interference, channel overlap, and signal degradation.
• Configure and optimize wireless security protocols, including WPA3, 802.1X, RADIUS, and EAP.
• Network Security and Compliance:
• Configure and manage firewall rules, VPNs, and security policies to protect network resources and ensure compliance with security standards.
• Perform regular security assessments, vulnerability scans, and audits to identify and mitigate security risks.

• Network Monitoring and Maintenance:
• Implement and maintain network monitoring systems to proactively detect and resolve issues before they impact operations.
• Perform regular maintenance tasks, such as firmware upgrades, configuration backups, and patch management for network devices.
• Maintain accurate network documentation, including network diagrams, device configurations, and procedures.
• Collaboration and Mentorship:
• Work closely with cross-functional teams (e.g., systems, security, applications) to integrate network solutions and ensure seamless operation.
• Provide mentorship, training, and guidance to L1 and L2 engineers to help them develop their technical skills and knowledge.
• Participate in technical workshops, knowledge-sharing sessions, and project planning meetings.
• Process Improvement and Automation:
• Identify opportunities to improve network processes and workflows to increase efficiency and reduce manual effort.
• Develop automation scripts and tools (e.g., Python, Ansible) to streamline network configuration, monitoring, and management tasks.

• Certifications: Relevant certifications such as CCNP Wireless, CCNP Enterprise, CCNP Security, CWNA/CWSP, PCNSE, or equivalent are highly desirable.
• Technical Skills:
• • In-depth knowledge of wireless networking standards (802.11a/b/g/n/ac/ax), WLAN design, and RF optimization.
  • Expertise in Layer 2/3 switching technologies, including VLANs, STP, LACP, HSRP/VRRP, and VSS/VPC.
  • Proficiency in configuring and managing firewalls (e.g., Cisco ASA/Firepower, …
