Cisco Network Engineer

The Cisco Network Engineer plays a critical role in designing, implementing, managing, and continuously optimizing the enterprise network infrastructure built on Cisco hardware and software platforms. This individual is accountable for the performance, reliability, availability, and security of complex LAN/WAN environments that underpin all business operations. Working cross-functionally with IT, cybersecurity, and operations teams, the engineer serves as a trusted technical advisor ensuring the network aligns with and actively supports evolving business objectives. This role sits at the strategic intersection of infrastructure operations and network architecture, requiring both deep hands-on expertise and the ability to plan for long-term scalability and resilience., * Design, deploy, configure, and maintain Cisco routers, switches, firewalls, and wireless infrastructure across enterprise environments.

• Implement and manage dynamic routing protocols including OSPF, EIGRP, BGP, and MPLS to ensure optimal path selection and network convergence.
• Configure and manage Cisco SD-WAN (Viptela / Catalyst SD-WAN) and SD-Access solutions to support distributed branch and campus deployments.
• Plan, implement, and maintain VLANs, Spanning Tree Protocol (STP/RSTP), VTP, QoS policies, and network segmentation strategies.
• Manage Cisco ASA and Firepower (FTD) firewalls and administer Cisco Client for network access control, 802.1X enforcement, and policy-based segmentation.
• Monitor network performance, capacity, and availability using tools such as Cisco DNA Center, SolarWinds, PRTG, NetFlow, or equivalent enterprise platforms.
• Perform thorough root-cause analysis, troubleshoot complex Layer 2 and Layer 3 issues, and resolve network outages within defined SLA parameters.
• Implement and maintain IPsec VPN, DMVPN, and remote access VPN solutions to support secure connectivity for branch offices and remote users.
• Develop, maintain, and update network architecture diagrams, runbooks, standard operating procedures, and change management documentation.
• Collaborate actively with security teams to enforce network security policies, access control lists (ACLs), firewall rule sets, and micro-segmentation strategies.
• Support hybrid and cloud connectivity requirements including AWS Direct Connect, Microsoft Azure ExpressRoute, and Google Cloud Platform Interconnect integrations.
• Automate repetitive network tasks and drive operational efficiency using Python scripting, Ansible playbooks, or Cisco NSO.
• Participate in 24/7 on-call rotation to provide timely response and resolution for critical network incidents and escalations.
• Continuously evaluate and recommend new Cisco technologies, platform upgrades, and industry best practices to enhance network performance, security posture, and business resilience., CISCO PLATFORMSCisco Platforms Catalyst 9000 Series, Nexus 7K/9K, ASR 1000/9000, ISR 4000, Firepower/FTD, ASA, Meraki, Cisco Client, DNA Center / Catalyst CenterCatalyst 9000 Series, Nexus 7K/9K, ASR 1000/9000, ISR 4000, Firepower/FTD, ASA, Meraki, Cisco Client, DNA Center / Catalyst Center Protocols & Technologies BGP, OSPF, EIGRP, MPLS, DMVPN, IPsec VPN, STP/RSTP, VLANs, QoS, VXLAN, EVPN SD-WAN / SDN Cisco Viptela SD-WAN, SD-Access, Cisco ACI (preferred) Security Cisco Firepower, ASA, Client, Cisco Umbrella, TACACS+/RADIUS, ACLs, 802.1X Cloud Networking AWS Direct Connect, Azure ExpressRoute, Google Cloud Platform Interconnect Automation & Tools Python, Ansible, NETCONF/RESTCONF, Cisco NSO, Git Monitoring & Diagnostics Cisco DNA Center, SolarWinds, PRTG, Wireshark, NetFlow
