Network Engineer IVThe Network Engineer IV is responsible for administration, monitoring, and support all aspects of the network infrastructure including deployment, operations, maintenance, and troubleshooting high complexity WAN/LAN/Switching/Routing issues. The Network Engineer IV will design and create Layer 2/3 network architectures for hybrid environments. In addition, the Network Engineer IV will analyze current processes and procedures for possible improvement as well as develop and maintain documentation of their assigned environment. The Network Engineer IV is the primary IT contact for Reliance business units and will provide escalation response for issues. The Network Engineer IV serves as the technical resource for secure network design, managing standards, patterns, and reference architectures across WAN, LAN, data center, cloud, and network security domains. This role partners closely with information security, infrastructure, and application teams to ensure consistent, secure, and well-documented implementations. This role operates as a security-aligned Engineer reporting into the Office of the CISO and is accountable for administering and supporting hybrid network architectures spanning on-premise data centers and public cloud environments. The Network Engineer IV will contribute to designing resilient, secure connectivity supporting mission-critical applications hosted across redundant data centers and AWS and Azure cloud platforms, serving more than 300 branch locations. All network designs must align with Zero Trust architecture principles and enterprise security strategy.
