Position Overview

Our client is looking for a Senior Network Engineer to join its Infrastructure team and help operate and support the organization's enterprise network. This is a core Cisco networking role covering routing, campus switching, and data center switching, with additional responsibility for helping manage the organization's Palo Alto firewall environment. The ideal candidate is a seasoned, hands-on engineer who is comfortable owning day-to-day operations, troubleshooting complex issues, and working directly with the internal engineering team in a financial services environment.


Key Responsibilities
• Design, configure, and troubleshoot enterprise routing across the WAN and data center environment (BGP, OSPF, static routing).
• Manage and support campus switching infrastructure, including VLANs, spanning tree, QoS, and 802.1X network access control across wired and wireless environments.
• Manage and support data center switching, including Cisco Nexus and ACI fabric operations (APIC, spine/leaf, EPGs/bridge domains, L3Outs, fabric policy).
• Help administer and maintain the Palo Alto Networks firewall environment (Panorama-managed HA pairs), including security and NAT policy, GlobalProtect VPN, and day-to-day rule and policy changes.
• Monitor network health and performance, and lead troubleshooting and root-cause analysis for routing, switching, and firewall-related incidents.
• Support wireless network operations, including controller configuration and ongoing performance tuning.
• Configure and maintain site-to-site VPN and third-party network circuit integrations, including BGP peering with carriers and service providers.
• Plan and execute changes to network and firewall infrastructure through a formal change management process, including work during scheduled maintenance windows.
• Maintain accurate network documentation, including diagrams, configurations, and as-built records as the environment evolves.
• Collaborate with the broader Infrastructure, security, and systems teams on cross-functional projects and day-to-day operational needs.


Required Qualifications
• 7+ years of hands-on experience as a network engineer in an enterprise environment.
• Strong Cisco routing and switching, including BGP/OSPF, campus switching, VLANs, and spanning tree.
• Experience with Cisco data center switching (Nexus; ACI fabric experience strongly preferred).
• Experience administering or supporting Palo Alto Networks firewalls (Panorama-managed environments a plus).
• Working knowledge of 802.1X, VPN technologies (site-to-site and remote access), and wireless networking.
• Strong troubleshooting skills and the ability to work independently on complex, multi-layer network issues.
• Solid documentation habits and the ability to communicate clearly with internal stakeholders.
• Work on-site in Colorado Springs, CO on a regular basis and support after-hours maintenance windows as needed.


Preferred Qualifications
• Cisco certification (CCNP or higher), with data center or enterprise routing/switching focus.
• Palo Alto Networks PCNSE certification or equivalent firewall administration experience.
• Experience with Cisco ACI Multi-Pod/Multi-Site architecture and Nexus Dashboard Orchestrator (NDO).
• Prior experience supporting network infrastructure for a financial institution or other regulated environment.
