Technical Architect

About the job

We have an urgent contract opportunity for a hands-on Senior Technical Architect to play a leading role in the biggest technology transformation programme our client has ever undertaken.

Map the AS-IS business processes and technology landscape, including the two core legacy systems, Microsoft ESB, integrations, interfaces, data flows and satellite applications.

Translate business requirements and processes into a clear TO-BE architecture and technical blueprint.

Produce High-Level Designs (HLDs), architecture diagrams, UML diagrams, integration models and supporting architectural artefacts.

Design how the new SaaS platform fits into the wider technology ecosystem rather than viewing it in isolation.

Define the integration architecture across operational systems, courier applications, optimisation solutions, scanning and measuring technology, SaaS platforms and third parties.

Help drive the move towards a modern Azure and event-driven architecture, including event buses, real-time messaging, APIs and appr...
