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.

Requirements

What You'll Be Doing

• Designing, implementing, and troubleshooting IoT solutions end to end
• Onboarding IoT devices onto the network using Cisco DNA Center
• Integrating sensors, actuators, and communication modules into IoT systems
• Developing network strategies using DNAC to isolate and secure IoT traffic
• Implementing security measures to protect IoT devices and data
• Evaluating and feasibility-testing IoT solutions and documenting findings
• Designing networks that can scale to accommodate future IoT growth
• Documenting system architecture, design specs, and troubleshooting procedures

​

What We Need

• Cisco SD Access, DNA Center (DNAC), and VxLAN — production delivery, not certification only

IoT protocols

MQTT, CoAP, Thread

Programming experience

C, C++, Python, Java

Cloud IoT platforms

AWS IoT or Azure IoT

• Security best practices for IoT devices and networks
• Hardware integration experience — sensors, actuators, firmware
• 5–8 years' experience in IoT development and network engineering
