Job description
We are seeking an experienced SAP Integration Architect to play a critical role in the Landmark Programme, a major transformation initiative to:
- Migrate from SAP ECC to SAP S/4HANA
- Decouple non-finance capabilities from SAP
- Enable full decommissioning of SAP ECC before 2030
This programme addresses a highly complex legacy environment where SAP ECC has become tightly coupled with multiple business processes and systems, creating a bottleneck for change and innovation.
The Integration Architect will lead the design of a simplified, modular integration landscape that enables agility, reduces technical debt, and supports a modern, domain-driven architecture.
Key Objectives of the Role
- Design and govern integration architecture across:
o Legacy SAP ECC
o SAP S/4HANA (Finance core)
o Domain-driven business systems
- Enable the decoupling strategy by:
o Removing non-finance functionality from SAP
o Redirecting data flows to domain platforms or integration layers
- Reduce complexity by transitioning from:
o A highly coupled SAP-centric architecture
o To a modular, loosely coupled ecosystem
- Support delivery of:
o Integration Strategy
o Integration Architecture Design
o Interface Specifications & build oversight
What You'll Be Doing
Architecture & Design
- Define the target integration architecture aligned to S/4HANA as the finance system of record.
- Establish integration patterns (APIs, events, messaging) tailored to a decoupled landscape
- Ensure adherence to programme guiding principles, including:
o Minimum Viable Integration.
o Standard first, exception by design.
Decoupling & Transformation
- Liaise with the other business transformation programmes that will need to into create new integration designs for removing non-finance capabilities from SAP ECC
- Redesign outbound and inbound interfaces:
o Repoint integrations to domain systems
o Reduce SAP's role as a central data distribution hub
- Support the move towards:
o Domain ownership of data
o Increased pace of change across business areas
Delivery & Governance
- Own or contribute to key artefacts:
o Integration Strategy
o Interface Specifications
o Non-functional requirements (performance, scalability, resilience)
- Work across delivery phases:
o Design * Build * Test * Deploy (SAP Activate aligned)
- Provide technical oversight of:
o Integration build and test activities
o Vendor-led delivery (multi-partner model)
Collaboration & Stakeholders
- Work closely with:
o Enterprise Architecture teams across M&S Digital and Tech.
o SAP functional teams (Finance, PTP, OTC, etc.)
o Domain system teams (Supply Chain, Product, Pricing)
- Partner with system integrators and specialist vendors across the programme
Requirements
- Strong SAP integration experience across:
o SAP ECC and SAP S/4HANA
- Demonstrated experience in large-scale transformation programmes
- Experience designing integration solutions in complex, highly integrated environments
Technical Skills
- Deep understanding of:
o Enterprise integration patterns (API, event-driven, messaging)
o Interface-based integration (IDocs, services, batch, etc.)
o Data flow and system decoupling strategies
- Experience working with:
o Multi-system landscapes (ERP + domain systems)
o Integration platforms and middleware
Architecture & Design Capability
- Proven ability to:
o Design scalable, modular integration architectures
o Simplify complex estates and reduce dependencies
- Familiarity with:
o Domain-driven / service-based architectures
Soft Skills
- Strong stakeholder engagement and influencing skills
- Ability to operate in multi-vendor, matrix environments
- Commercially aware, outcome-driven decision making
