You'll design, implement, and operate IoT network solutions for an enterprise client. The core of the role is building and managing IoT connectivity infrastructure — onboarding devices, designing isolation and security strategies, and keeping everything running reliably as the IoT estate grows.

Cisco SD Access, DNA Center, and VxLAN are must-haves. If you don't have hands-on production experience with all three, this isn't the right role. The client needs someone who has delivered with these tools — not just familiarity.

•      Designing, implementing, and troubleshooting IoT solutions end to end

•      Onboarding IoT devices onto the network using Cisco DNA Center
