Domain Integration Architect

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.

The consultant will work closely with Product Area teams and Integration Platform teams to establish clear domain boundaries, expose System and Process APIs, implement event-driven patterns, and progressively modernize a complex SAP-centric landscape.

Key Responsibilities

• Build an inventory of existing integrations, including APIs, batch files, custom SAP developments, RFCs and legacy point-to-point interfaces.
• Assess existing technical debt and identify high-priority integration dependencies to modernize.
• Facilitate collaboration between Product Area teams and Integration Platform teams working with Kong, Solace, SAP CPI and MuleSoft.
• 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.

Required Skills & Experience

• Strong experience in Enterprise Integration Architecture.
• Solid knowledge of Domain-Driven Design (DDD) principles.
• Hands-on experience with API-led connectivity and event-driven architectures.
• Strong experience with at least one of the following technologies:
• MuleSoft
• SAP CPI
• Solace
• Kong
• Proven experience modernizing SAP-centric integration landscapes.
• Knowledge of modernization patterns such as Strangler Fig, Anti-Corruption Layer (ACL), Change Data Capture (CDC) and Outbox patterns.
• Ability to work effectively with both engineering teams and senior stakeholders.
• Strong communication, facilitation and architecture coaching skills.

Key Deliverables

The consultant will contribute to the creation of a consolidated integration inventory, transformation dashboard and integration playbook, while supporting the delivery of concrete migration patterns across the different Product Areas. A structured handover and capability transfer plan will also be expected at the end of the engagement.

Mission Details

• Role: Domain Integration Architect
• Start Date: ASAP
• Duration: 12 months
• Allocation: 4 days per week onsite
• Working Model: Hybrid – on-site / remote

This is a strategic and hands-on architecture role for someone who can combine enterprise architecture vision with pragmatic delivery, helping teams progressively transition toward a scalable, API-led and event-driven integration landscape.
