Integration Architect

Context & Objective

The integration of applications, partners, and third-party solutions plays an increasingly important role within modern IT landscapes. This role focuses on API-based and asynchronous integrations, cloud-native architectures, and the migration away from legacy integration platforms.

Standardisation, governance, and monitoring are key to ensuring efficient and high-quality project delivery. The Integration Centre of Excellence (DCoE) defines integration standards, evaluates new technologies, and develops common patterns and solutions. The team owns and manages core integration platforms and frameworks, working closely with delivery teams across the organisation.

The Integration Architect contributes both to project delivery and to the definition of guidelines, best practices, and architectural standards, with a strong focus on Microsoft Azure integration services.
