SAP Solution Architect

Job description

Job Summary Frasers Property Limited (“FPL”) is implementing OneERP, a group-wide programme to consolidate and standardise its enterprise systems onto SAP S/4HANA across its operating geographies. A System Integrator (“SI”) has been appointed and will provide its own solution architecture function as part of the implementation team. This is a client-side, FPL-engaged architecture position that exists to represent FPL's interests throughout design and build, ensuring the architecture delivered is the right long-term solution for the Group rather than the path of least resistance for the implementation partner. The successful candidate will work alongside the SI's architecture team, but their duty of care is to FPL, not to the SI's delivery timeline or cost position. The role provides independent, senior SAP S/4HANA architectural oversight for OneERP, ensuring that design decisions are technically sound, aligned to FPL’s long-term operating model, and free from shortcuts, unnecessary customisation, or scope compromises. This is fundamentally an assurance and governance role but also extends into delivery, through ongoing checks during build and test to confirm that what is actually implemented remains aligned with the agreed design. Job Description Architecture governance and assurance Own and maintain FPL's target architecture principles, standards, and guardrails for OneERP, holding the SI's architecture team accountable to them. Review and formally sign off, or reject with documented rationale, design artefacts produced by the SI, including blueprints, process designs, integration and data architecture, and technical specifications. Test proposed designs against FPL's actual business requirements, rather than accepting SAP best-practice or accelerator-based designs at face value where they do not fit FPL's context. Identify and escalate cases where the implementation favours speed, cost, or SAP accelerator content over correctness or fit for FPL, and require remediation before sign-off. Maintain a decision and design-deviation log capturing material trade-offs, options considered, and rationale, so decisions remain auditable beyond go-live. Delivery conformance Conduct ongoing reviews through build and test to verify that configuration, integration, and code delivered by the SI align with signed-off design artefacts, flagging and requiring correction of any drift. Participate in sprint reviews, test evidence walkthroughs, and pre-cutover checkpoints as an independent check on delivery fidelity, so conformance is verified continuously, not only at design sign-off. Where delivery has departed from the agreed design, decide whether to correct, formally re-approve, or escalate the deviation, and update the decision log accordingly. Technical leadership Lead architecture for the S/4HANA core, including finance, procurement, real estate-specific processes, and integration with surrounding systems (property management, treasury, consolidation and reporting via OneStream, and data platforms). Define and enforce integration and data architecture, including master data governance, interface standards, and the boundary between core S/4HANA and satellite systems. Assess and rule on custom development ("Z" objects), workarounds, and configuration exceptions proposed by the SI, applying a clean-core philosophy and requiring justification for deviations. Provide architectural input into environment strategy, landscape design, cutover and migration approach, and non-functional requirements such as performance, scalability, and security. Chair or co-chair the architecture review board, with authority to block designs that do not meet FPL's standards. Stakeholder management Act as the primary architecture contact for FPL business unit stakeholders and process owners, translating business requirements into architectural requirements the SI must meet. Provide the Programme Director and Steering Committee with independent, plain-language assessments of architectural risk and design quality, including where the SI's approach falls short. Work collaboratively with the SI's architecture team day to day, while maintaining independence of judgement and escalating disagreements through governance rather than delivery pressure. Knowledge transfer and sustainability Ensure the design is documented to a standard that lets FPL operate, extend, and govern the solution independently of the SI after go-live and post-contract support. Build architectural capability within FPL's Enterprise Systems team, so the organisation is not permanently dependent on external parties for architectural decisions. Key Qualification Minimum 12 years of SAP experience, including at least 5 years in an S/4HANA solution or enterprise architect capacity on large, multi-country implementations. At least one prior engagement having served in a client-side architecture or architecture assurance capacity overseeing a Tier 1 systems integrator (such as Deloitte, IBM, Capgemini, or equivalent), rather than working as part of the SI team itself. Demonstrated depth across core S/4HANA modules (FI/CO at minimum), with working knowledge of real estate, property, or asset-intensive industry processes an advantage. Strong grounding in integration architecture (SAP BTP/Integration Suite or equivalent), data migration approaches, and clean-core principles for S/4HANA. Familiarity with financial consolidation and group reporting systems, particularly OneStream, and how they integrate with S/4HANA, as OneStream forms part of the overall solution landscape. Experience operating across multiple countries and regulatory environments; exposure to Southeast Asia, Australia, and European operating contexts is an advantage given FPL's footprint. SAP architecture-level certification (e.g. SAP Certified Technology Architect, or equivalent S/4HANA architecture credential) preferred. Bachelor's degree in Computer Science, Information Systems, Engineering, or a related discipline; a relevant Master's degree is an advantage.
