Mid/Sr Level Network Engineer

Do you have experience in Wireless network configuration?, *At least CCNA or CCNP is a must

*Very detailed job description and required skill set

*You must be a good fit skill set and professionally. *Core Focus: Strong L2-L7 understanding, routing/firewall/Wi-Fi integration, and Network Access Control (NAC).

Skills - Must Have

• Layer 2, foundational Layer 3, and introductory Wi-Fi concepts. L2 switching (i.e. fully understand VLANs, tagging, trunking, AAA, Spanning Tree, etc.) and foundational knowledge of L3 networking

Skills - Nice to Have

• Strong L2-L7 understanding, routing/firewall/Wi-Fi integration, and Network Access Control (NAC). Should have an in-depth understanding of L2 switching and a strong understanding of L3 through 7 networking, routing protocols, firewalls, WiFi and NAC.

Should have an in-depth understanding of L2 switching and a strong understanding of L3 through 7 networking, routing protocols (OSPF, EIGRP), firewalls, Wi-Fi, and Network Access Control (NAC - for example ISE and/or CPPM). They should also have a basic understanding of more complex topics like VRFs, BGP, and MPLS.

Technical Skills

• Layer 2 / Layer 3:
• Advanced VLAN design and trunking
• EtherChannel / LACP configuration
• Advanced STP tuning (portfast, BPDU guard, root guard)
• Advanced OSPF and EIGRP configuration and troubleshooting
• Inter-VLAN routing and redundant gateways (HSRP, VRRP, GLBP)
• Introductory VRF and route leaking concepts
• Layer 4-7:
• Firewall concepts (stateful inspection, NAT, ACLs)
• Application layer troubleshooting (DNS, DHCP, HTTP, HTTPS)
• QoS basics (classification, marking, queuing)
• Wi-Fi (Intermediate Level):
• Wireless LAN Controller (WLC) configuration and management
• Understanding of RF design (channel planning, power levels, interference)
• Authentication and security (WPA2/3, 802.1X, RADIUS)
• Basic wireless site survey concepts
• Troubleshooting roaming, coverage, and throughput issues
• Network Access Control (NAC):
• Familiarity with Cisco ISE, Aruba ClearPass, or similar
• Device profiling and posture assessment basics
• Role-based access policies and VLAN assignment
• Emerging / Advanced Topics:
• Intro to BGP and MPLS
• VRFs and multi-tenant segmentation
• SD-Access / SD-WAN fundamentals
