Lead Solution Architect for RANi IT

The main purpose of this role is to take end-to-end ownership of functional solution architecture within the BM RANi (Best Mobile RAN Infrastructure) domain and to translate business vision and requirements into sustainable, scalable, and future-proof architectural solutions. 

This is not a programming or hands-on development role. It is a functional and strategic architecture role operating at the intersection of business and IT. 

As a Lead Solution Architect, you act in the role of HUB Architect. You receive business requirements from the business side and ensure their deep understanding – not only what needs to be delivered, but why it needs to be delivered and what business outcome is expected. 

In iterative steps, you transform these requirements into a coherent functional architecture that goes beyond the boundaries of the HUB itself. You consider cross-domain dependencies, integrations with internal and external partners, and collaboration with other mobile operators (OMC). You ensure that solutions fit into the broader enterprise and telco ecosystem. 

You define architectural direction, set guardrails, and ensure that every solution aligns with strategic architectural principles and long-term vision. 

ABOUT THE PROJECT

• Network planning and rollout (including 5G, Small Cells, and expansion of network structures) 

• Inventory, configuration, and optimization of the RAN 

• Integration with assurance, workforce control, and related support systems 

• Collaboration with internal and external partners as well as other mobile operators 

The business focus of BM RANi is to ensure high network coverage, high quality, capacity, and innovation — enabling Deutsche Telekom to maintain and further strengthen its “Best Network” position.
