• Configuring and supporting Cisco routers, Catalyst/Nexus switches, ASA firewalls, and Cisco Secure Firewall Threat Defense (FTD) appliances managed through FMC.
• Supporting routing and switching technologies including BGP, OSPF, EIGRP, VLANs, HSRP/VRRP, port channels, QoS, multicast, and network segmentation.
• Administering and troubleshooting firewall access-control policies, NAT, intrusion policies, site-to-site VPNs, remote-access VPNs, and SSL VPN/SAML integrations.
• Managing F5 BIG-IP LTM services, including virtual servers, pools, monitors, SSL profiles, persistence, iRules, traffic troubleshooting, and high availability.
• Supporting wireless infrastructure, including wireless LAN design, access-point deployment, SSIDs, authentication, guest access, and troubleshooting.
• Administering network access control solutions such as Aruba/HP ClearPass or equivalent platforms, including 802.1X, RADIUS, TACACS+, device profiling, and guest/BYOD access.
• Using NetBrain or equivalent tools for network discovery, documentation, mapping, automation, and troubleshooting.
• Using AlgoSec or equivalent firewall-policy management tools to analyze, validate, document, and implement firewall changes.
• Partnering with Security, Infrastructure, Cloud, Help Desk, and application teams to deliver secure, reliable connectivity.
• Participating in PCI, audit, vulnerability-remediation, and network-segmentation initiatives.
• Creating and maintaining network diagrams, standards, operational procedures, implementation plans, and support documentation.
• Leading or participating in network upgrades, migrations, acquisitions, and new-site deployments.
• Analyzing complex network incidents, performing root-cause analysis, and recommending long-term corrective actions.
• Participating in an on-call rotation and provide support during planned maintenance windows when needed.

Qualifications

• Bachelor's degree in Information Technology, Computer Science, or related field; equivalent professional experience will be considered.
• 7+ years of progressively responsible enterprise network engineering experience.
• Strong hands-on experience with Cisco routers, switches, ASA, and FTD firewalls.
• Strong understanding of TCP/IP, DNS, DHCP, NAT, VLANs, routing, switching, and network-security principles.
• Strong experience with dynamic routing protocols, especially BGP and OSPF.
• Experience supporting enterprise VPN technologies, including site-to-site IPsec and remote-access SSL VPN.
• Experience with F5 BIG-IP LTM, including virtual servers, pools, monitors, SSL/TLS, and high-availability configurations.
• Experience with NetBrain, AlgoSec, or comparable network automation, policy-management, or topology-mapping tools.
• Experience with enterprise wireless and network-access control solutions, preferably Aruba/HP ClearPass or equivalent.

• Experience working within formal change-management, incident-management, and problem-management processes.
• Strong written and verbal communication skills, including the ability to explain technical issues to both technical and non-technical stakeholders.

Preferred Qualifications

• Cisco certifications such as CCNP Enterprise, CCNP Security, or CCIE.
• F5 Certified Technology Specialist (CTS) or comparable F5 experience.

• Experience supporting cloud networking in AWS and/or Microsoft Azure.
• Experience in a regulated environment, particularly PCI DSS, financial services, or payment-processing environments.
• Experience with Zscaler, SASE, zero-trust, segmentation, or security-compliance tooling.
