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
