Enterprise Architect Health Customer - with German; m​/f​/d

Purpose Enterprise Architect is responsible / accountable for development and optimization of IT architecture on Enterprise level: for this purpose this role caries out analysis and evaluation of customer and technical requirements; develops implementation concepts and holds accountability for implementation.

Enterprise Architect assumes responsibility / accountability for all interactions of components, systems, functions from the network to the point of interaction with the customer; in this context, this role designs a comprehensive vision and co-create strategy taking into account high level business requirements and implications, with a view to sustainability.

Among previous, this role identifies and evaluates innovations in technology fields and being actively involved with implementation within the Group and in the industry (standardization, open source communities, suppliers, interest groups, patents, etc.).

• Assume end-to-end responsibility for the technical feasibility, consistency and documentation of network solutions.
• Create, maintain and continuously develop network landscapes covering data centers, workplace environments, cloud services, applications, external partners and network or security providers.
• Document network architectures, system relationships, connectivity paths, data flows, routing dependencies and security boundaries.
• Develop network solution designs in close collaboration with the responsible T-Systems units, customer teams and external providers.
• Translate customer and project requirements into production-ready technical specifications, including:

• IP addressing and subnet requirements

• Routing and switching configurations

• Firewall rules and security policies
