• Wireless Network Management: Assist in the deployment, configuration, and maintenance of wireless network equipment, such as access points, wireless controllers, and related infrastructure.
• Perform wireless network troubleshooting, including resolving issues related to signal interference, connectivity, and authentication.
• Support site surveys and optimize wireless network configurations to ensure adequate coverage, capacity, and performance.
• Switching and Routing: Configure and maintain Layer 2 and Layer 3 network switches, including VLANs, spanning tree protocol (STP), link aggregation (LACP), and routing protocols (e.g., OSPF, EIGRP).
• Troubleshoot issues related to VLAN misconfigurations, trunk ports, and Layer 2 loops, ensuring the stability of the switching environment.
• Perform regular checks and updates to ensure the network is running efficiently and securely.
• Firewall Administration: assist in configuring, managing, and maintaining firewalls from various vendors (e.g., Cisco ASA/Firepower, Palo Alto, Fortinet) to protect network resources.
• Troubleshoot firewall-related issues, such as access control lists (ACLs), VPN tunnels, and NAT configurations.
  Support the implementation of security policies and procedures to safeguard network infrastructure from potential threats.
• Network Monitoring and Documentation: use network monitoring tools (e.g., SolarWinds, Nagios, Cisco Prime, Aruba AirWave) to monitor network performance, identify issues, and generate reports.
• Maintain up-to-date network documentation, including network diagrams, device configurations, and incident logs.
  Provide regular status updates and reports on network performance and incidents to management and stakeholders.
• Collaboration and Coordination: work closely with L1 support teams to provide guidance, training, and technical support to resolve common network issues.
• Collaborate with L3 engineers and other IT teams to plan and execute network upgrades, patches, and migrations.
  Participate in network-related projects and assist in the implementation of new technologies and solutions.
• Continuous Improvement and Learning: stay updated with the latest network technologies, protocols, and best practices.
• Participate in training sessions, workshops, and certification programs to enhance technical skills and knowledge.

Technical Skills:

• Strong understanding of wireless networking concepts (802.11 standards, RF basics, wireless security).
• Knowledge of Layer 2 and Layer 3 switching concepts, including VLANs, STP, VTP, and routing protocols.
• Experience with firewalls (Cisco ASA/Firepower, Palo Alto, Fortinet) and security configurations (ACLs, NAT, VPNs).
• Familiarity with network monitoring and troubleshooting tools (Wireshark, SolarWinds, Cisco Prime).

Preferred Qualifications:

• Certifications: Relevant certifications such as CCNA, CompTIA Network+, CWNA, or equivalent are preferred.
• Experience with network automation and scripting (Python, Ansible) is a plus.
• Familiarity with cloud networking (AWS, Azure, GCP) and hybrid network environments.
• Understanding of network access control (NAC) solutions, such as Cisco ISE or Aruba ClearPass.
