We are looking for an experienced Domain Integration Architect to support a major transformation program focused on moving from tightly coupled, point-to-point integrations toward a composable, domain-driven integration architecture .

- Define and implement API-led connectivity and event-driven integration patterns .
- Support the transition toward a Domain-Driven Design (DDD) and composable architecture.
- Drive incremental modernization initiatives with short delivery cycles rather than large-scale Big Bang transformations.
- Define and monitor transformation KPIs, including coupling reduction, Process APIs exposed, events published and legacy interfaces retired.
- Coach technical teams on DDD, integration patterns and architecture best practices.
- Develop integration standards covering API naming, versioning, system/process layers and contract ownership.
- Ensure knowledge transfer and capability building across the organization.
