Integration Architect

Job title: Integration Architect

Contract: six months

Location: London (hybrid)

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

Candidate Profile

Experience

• 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

Why Join This Programme?

• Work on a business-critical transformation with a clear deadline (ECC decommissioning before 2030)
• Help reshape a landscape currently constrained by:

o High complexity

o Slow change cycles due to SAP dependency

• Deliver tangible outcomes such as:

o Reduced technical debt

o Faster business change

o Simplified architecture and improved performance
