The role combines architecture, hands-on technical implementation, development leadership, and coaching responsibilities. The assignment requires a senior profile capable of designing scalable integration architectures, leading development teams, contributing to implementation activities, and ensuring knowledge transfer. Your missions Evolve and maintain a hybrid integration platform connecting Azure-based and legacy/private-cloud applications. Define technical architectures for solutions built on the integration platform. Support the implementation of Enterprise Data Management (EDM) repositories and authoritative data source subscription mechanisms. Contribute to the evolution and maintenance of solutions developed on the integration platform. Design and implement integration patterns, API strategies, microservices, and event-driven architectures. Lead development activities and provide technical guidance to the development team. Participate actively in software development when required. Support GIS-related initiatives, including spatial data management and geospatial processing. Ensure technical documentation, knowledge transfer, and coaching of developers. Your activities Architecture & Design Produce High Level Designs (HLD). Define technical architecture designs and implementation roadmaps. Create technical analysis and architecture documentation. Design hybrid integration architectures involving Azure and private cloud/legacy environments. Define event-driven architectures using Azure messaging and integration services. Design Topics, Queues, Subscriptions, and data dissemination strategies aligned with business and data flow requirements. Integration & Platform Evolution Evolve the existing integration platform. Define and implement integration solutions between multiple information systems. Design and maintain API, SOA, and microservices-based architectures. Ensure interoperability between cloud and legacy systems. Implement secure integration patterns using REST, SOAP, and WS-Security. Enterprise Data Management Design and implement data repositories and master/reference data solutions. Define governance approaches for authoritative data sources. Implement subscription and synchronization mechanisms with authoritative data sources. Support data governance and contextual data management initiatives. GIS & Spatial Systems Contribute to GIS architecture and implementation. Manage repositories of points of interest (POI). Design and optimize spatial calculations, including distance calculations and isochrone processing. Implement geospatial processing solutions using appropriate GIS frameworks and libraries. Development & Leadership Lead and coordinate development teams. Participate in the development of solutions using Java technologies and modern frameworks. Review technical implementations and ensure architectural compliance. Produce technical documentation. Deliver handovers and coach developers to ensure knowledge transfer and sustainability of solutions. Compliance & Data Protection Ensure solutions comply with data protection and GDPR requirements. Integrate security, privacy, and compliance considerations throughout the software development lifecycle.
