Overview

We Make Life More Rewarding and Dignified Location: LibertyvilleDepartment: Information Technology SummaryThe Manager, Network Engineering and Administration is responsible for the leadership, operational stability, engineering standards, and continuous improvement of the enterprise network environment. This role leads network engineering and network administration activities across Enterprise Network and Operational Technology (OT) Network environments, including LAN, WAN, wireless, internet connectivity, remote access, core services, and related infrastructure components to ensure the network foundation is secure, resilient, scalable, and aligned with business requirements.The role is accountable for network availability, high availability design, performance optimization, capacity planning, proactive monitoring, incident response, and disciplined change execution according to industry best practices. The Manager establishes operational standards, strengthens monitoring and observability, mitigates risk through strong control discipline, and drives automation and infrastructure as code practices where appropriate to improve consistency, speed, recoverability, and service efficiency across both enterprise and OT network services. This leader partners closely with Infrastructure, Cybersecurity, Cloud, Application, Manufacturing, and business teams to ensure network services remain dependable, supportable, and ready to meet current and future enterprise needs.ResponsibilitiesNetwork engineering leadership and service ownership Lead network engineering and administration function with accountability for enterprise and operational technology (OT) network environments, including LAN, WAN, wireless, internet connectivity, VPN, routing, switching, core network services, and related infrastructure. Establish and maintain network engineering standards, operating procedures, support models, escalation paths, lifecycle planning, and documentation to ensure consistent, supportable service delivery across enterprise and OT domains. Manage day-to-day network operations and engineering priorities, balancing operational support, project delivery, modernization, and business service expectations across office, data center, remote, and plant-connected environments.Availability, high availability, and monitoring Design, operate, and continuously improve network services for high availability, resiliency, recoverability, and business continuity using redundancy, failover, segmentation, and recovery strategies across enterprise and OT environments. Own network monitoring and observability strategy, including health monitoring, fault detection, alerting, event correlation, and service visibility across enterprise, OT, and cloud-connected environments. Ensure incidents, outages, degradations, and recurring faults are addressed with urgency through structured response, timely escalation, root cause analysis, and corrective actions to reduce repeat occurrences across enterprise and plant-connected OT environments.Performance optimization, capacity, and continuous improvement Establish measurable standards for network performance, latency, throughput, packet loss, utilization, service availability, and responsiveness, using metrics to guide engineering decisions and service improvements across enterprise and OT services. Lead capacity planning, performance trending, technology refresh, and optimization initiatives to maintain stable, scalable networks aligned to business demand, plant operations, and manufacturing connectivity requirements. Drive process standardization, automation, and infrastructure as code practices to reduce manual effort, improve change quality, increase repeatability, and accelerate delivery of network services.Risk mitigation, security alignment, and operational control Mitigate operational and technology risk through disciplined configuration management, segmentation, access control coordination, patching, firmware currency, v
