Position Summary

We are seeking a senior Network & Network Security Deployment Engineer to lead the technical execution of an enterprise-wide branch network refresh. The primary mission is to migrate the existing Palo Alto Prisma SD-WAN (ION) fabric to a Cisco Meraki MX SD-WAN architecture across the combined Synovus/Pinnacle branch footprint, while concurrently refreshing the branch LAN (Juniper EX2300 and Cisco Catalyst 9300 access switches) and integrating Cisco Meraki MR wireless. The role is build-focused: design validation, site cutover, documentation, and operational handover to the run team.

Core Technical Implementation

SD-WAN Migration (Primary Focus)

• Decommission Palo Alto Prisma SD-WAN ION appliances and replace with Cisco Meraki MX (MX85/MX95/MX105 class) at branch and regional sites.
• Translate Prisma path policies, application steering, QoS, and security zones into equivalent Meraki SD-WAN traffic-shaping, AutoVPN hub-and-spoke, and L3/L7 firewall constructs.
• Configure Meraki AutoVPN mesh/hub topologies, SD-WAN+ performance probes, dual-ISP failover, and dynamic path selection.
• Coordinate WAN circuit transitions (MPLS / DIA / broadband / LTE failover) with carriers during cutover windows.
• Validate routing convergence with upstream BGP/OSPF peers at the datacenter aggregation layer.

Branch LAN Refresh & Wireless

• Provision and deploy Juniper EX2300 access switches (Junos config, Virtual Chassis, VLANs, 802.1X, LLDP-MED, PoE) at legacy Pinnacle sites.
• Provision and deploy Cisco Catalyst 9300 access switches (IOS-XE, StackWise, VLANs, 802.1X with Cisco ISE, QoS, MACsec where required) at Synovus sites and standardized branches.
• Deploy and tune Cisco Meraki MR wireless access points (SSID strategy, RF profiles, group policies, 802.1X/PSK, guest isolation).
• Implement consistent VLAN, IP addressing, and STP root standards aligned to the merger Re-IP strategy.

Network Security

• Deploy and configure Palo Alto NGFW (PAN-OS): security policies, NAT, IPsec/GlobalProtect VPN, Threat Prevention, URL filtering, decryption.
• Integrate branch enforcement with Cisco ISE (802.1X, MAB, posture) and align with the bank's NAC standards.
• Validate east-west and north-south traffic flows post-cutover against the security baseline.
