IoT Technical Manager in London

Shape the IoT Architecture of one of the world\’s most advanced office environments

We\’re partnering with a leading facilities management company responsible for operating one of the most modern and prestigious office developments globally. This is not a lab project or a theoretical IoT role. This role focuses on bringing a live, complex, mission‐critical smart building ecosystem into long‐term operation.

They are now looking for an IoT Subject Matter Expert to take technical ownership of their connected building architecture and ensure that tens of thousands of assets transition cleanly from project delivery into stable, data‐driven operations.

If you understand how IoT actually works in the real world, across buildings, infrastructure, data, and people, this role gives you genuine influence.

The opportunityYou will act as the technical authority for IoT and connected systems, bridging engineering, data, and operational teams. A major focus of the role is ensuring the accuracy, structure, and integrity of asset data, up to approximately 13,000 devices, during commissioning, close‐out, and handover.

In short, you will create and protect a single source of truth for a highly complex smart building, reducing operational risk and enabling long‐term value from data.

This role suits someone who does not just connect devices, but designs ecosystems that scale, remain secure, and deliver commercial and operational outcomes.
