Network Engineer

Old Republic is seeking a Network Engineer to design, deploy, and support enterprise routing and switching infrastructure connecting its data centers, corporate offices, and subsidiary branches. The role manages day-to-day network operations and project delivery across Cisco routing and switching, SD-WAN, and Meraki, while supporting resilient, consistent connectivity across the organization.

Responsibilities

Design, configure, and support enterprise Layer 3 routing including BGP, OSPF, static routing, route redistribution, summarization, route maps, prefix lists, and VRF segmentation

Deploy and maintain Cisco Catalyst switching (9200/9300/9500 class), including stacking, trunking, VLANs, SVIs, port channels, spanning tree, HSRP/VRRP, and QoS

Operate and expand the SD-WAN fabric on Silver Peak / Aruba EdgeConnect, including overlay policy, tunnel health, peer priority, path selection, and branch appliance deployment

Administer Cisco Meraki (MX, MS, MR, Z-series) for branch, teleworker, and wireless connectivity, including AutoVPN, SSID configuration, and dashboard templates

Build and maintain site-to-site IPsec VPNs and cloud connectivity, including Azure ExpressRoute and VPN gateway peering

Support routed integration with edge and security platforms such as Palo Alto firewalls and Zscaler tunnels, working with the security team on policy-based routing and traffic steering

Lead network changes end to end: design, peer review, change record, implementation window, validation, and rollback plan

Troubleshoot complex Layer 1 through Layer 3 issues using packet captures, interface counters, routing tables, traceroute, and log analysis, and drive root cause to closure

Execute site builds, hardware refreshes, circuit turn-ups, and branch cutovers with minimal business disruption

Maintain DNS, DHCP, and IPAM (DDI) records and IP address space in support of routed environments

Monitor network health and capacity, tune alerting, and recommend improvements to availability and performance

Produce and maintain as-built diagrams, standard configuration templates, runbooks, and build guides so subsidiaries can adopt consistent designs

Partner with subsidiary engineers, service desk teams, and carriers or vendors to resolve escalations and manage circuit and hardware lifecycle
