Your profile

4+ years of experience in networking, with a solid understanding of VPNs, NAT, firewalls, routing, and MPLS fundamentals

Hands-on experience configuring and managing IoT devices such as routers, cameras, sensors, and digital displays

Ability to evaluate how new devices fit into a broader site architecture, collaborate with vendors on integrations, and translate solutions into scalable standards
