Job Summary:
The Network Engineer III is responsible for evaluating, supporting, implementing and monitoring Network Management Toolsets also, implements complex multi-site network solutions, leads projects, and serves as an escalation point for the team.
Essential Functions:

• Design and implement data center switching/routing architectures (Cisco and Arista) including spine-leaf fabrics, MLAG/VXLAN, and inter-DC interconnects

• Own physical capacity planning for owned and co-located data centers: rack/power/cooling capacity forecasting, cabinet and cross-connect layout standards, and structured cabling design

• Manage relationships and SLAs with co-location providers and circuit/carrier vendors, including contract renewals, remote-hands escalations, and facility maintenance coordination

• Lead data centerbuild-outs, expansions, and equipment refresh/lifecycle projects, including coordination of electrical, mechanical, and physical security requirements with facilities and co-location partners

• Lead cloud connectivity initiatives (Direct Connect/ExpressRoute, transit gateways/virtual WANs, cloud routing strategy) in coordination with cloud infrastructure and security teams

• Serve as the primary network point of contact for cross-functional projects with the Security team, translating network architecture and traffic requirements into clear inputs for firewall, segmentation, and zero-trust initiatives without performing the security configuration itself

• Lead root-cause analysis for major or recurring network incidents and complex multi-domain outages (LAN/WAN/DC/cloud)

• Develop network standards, reference architectures, and lifecycle/capacity plans for switching, routing, and SD-WAN platforms

• Lead and review changes for high-risk or complex maintenance windows; act as escalation point for Level I/II engineers
