T Hub – Senior Product Owner (MNO Integration & CMP)

We are launching a strategic technology project to enable seamless global IoT connectivity by simplifying how international partner platforms are integrated and operated. The initiative focuses on building a common integration layer that abstracts the complexity of diverse external APIs and allows connectivity services to be delivered in a consistent, scalable, and automated way.

At the heart of the project is the development of a Connectivity Management Platform Adapter – a modern, extensible solution that connects multiple partner networks with internal systems, and directly supports the delivery of global IoT services for enterprise customers.
