• Provide engineering guidance to Operations and Implementation teams.
• Support complex technical escalations and design-related problem resolution.
• Ensure adherence to global architecture, security and configuration standards.
• Participate in change advisory reviews for design-impacting changes.
• Maintain architecture documentation, design standards, network diagrams and knowledge articles.

Deep knowledge of L2/L3 switching and routing (VLANs, STP, LACP, OSPF/BGP), wireless standards (802.11ac/ax/be across 2.4, 5 and 6 GHz) and network access security (802.1X, RADIUS, NAC, WPA3) is required.
