About The Position

The Senior Network Engineer ensures that service-provider delivery of managed network services meets HAEA’s network and business requirements. The role requires in-depth knowledge of network infrastructure—including LAN and switching, DNS/DHCP, WAN, load balancers, VoIP, and VPN—to resolve complex incidents and problems and maintain stable, reliable infrastructure that meets availability requirements and contracted service levels. The engineer provides senior-level technical expertise in planning, designing, implementing, and supporting network infrastructure for manufacturing and Operational Technology (OT) environments. A particular focus is Cisco Identity Services Engine (ISE) and Network Access Control (NAC), including administration and support of posture, profiling, authentication, authorization, and access-control capabilities. The role also manages vendor technical performance, network-specific contracts and suppliers, customer business-request priorities, project schedules and budgets, and service-provider performance. The position is based on-site in West Point, Georgia, five days per week.
