Network IoT Operations Engineer

About the Role

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.
