The Domain Architect acts as a trusted advisor partnering with the customers on their needs. Understands and captures the critical inputs of stakeholders and translates them into effective requirements and solutions. Specifies and designs effective end-to-end solutions incl. customer-specific adaptations by using the Nokia portfolio of products, systems and / or services as well as 3rd party products where required. Applies solution architecture standards, processes, and principles to create and maintain a solution's (technical) integrity over time. The Domain Architect leads end-to-end solution architecture for customer programs within the Telecom domain. This role defines, designs, and governs complex architectures across Cloud Native Solutions and emerging 5G/6G technologies—ensuring technical integrity, customer value, scalability, and lifecycle sustainability
