Start Date: 12th October 2026

Project: SAP S/4HANA Public Cloud Evolution

About the Role

Our client is a global, purpose-led organisation delivering high-impact projects that shape public policy and drive social change. We are seeking an experienced SAP Solution Architect to own and evolve a live SAP S/4HANA Public Cloud landscape. This is not a greenfield implementation role — the successful candidate will support, stabilise, and continuously improve a system already in production, driving process optimisation, release readiness, and cross-functional design integrity across core finance and operational processes.

The role requires deep, hands-on process ownership across Procure-to-Pay (P2P), Order-to-Cash (O2C), and Record-to-Report (R2R), alongside a strong command of Professional Services processes, and technical fluency in role/authorisation management and workflow design.

Key Responsibilities

• Act as the primary Solution Architect for the live S/4HANA Public Cloud environment, owning end-to-end process design and system integrity across P2P, O2C, and R2R.
• Manage the SAP Public Cloud release cycle: assess quarterly updates, run impact analysis, coordinate regression testing, and ensure business continuity through each release.
• Translate business requirements into fit-to-standard solution designs within the constraints of SAP Public Cloud's clean-core methodology, using standard configuration and the Business Technology Platform (BTP) for extensions where required.
• Own and maintain the roles and authorisations framework — actioning, designing, reviewing, and governing business roles, restriction types, and segregation-of-duties (SoD) controls.
• Design, configure, and troubleshoot SAP Business Workflow processes across approval chains (e.g. purchase requisitions, invoices, journal entries, sales orders).
• Provide architectural oversight for Professional Services processes — resource management, project billing, time and expense capture, and revenue recognition integration with R2R.
• Partner with Finance, Procurement, Sales, and Delivery/PS teams to identify process improvement opportunities and translate them into system enhancements.
• Manage integration touchpoints between P2P, O2C, R2R, and Professional Services modules, ensuring data and process consistency end-to-end.
• Lead root-cause analysis and resolution of live-environment incidents, working with SAP support (BCP/OCC) where escalation is required.
• Produce and maintain solution documentation, process maps, and design decisions for audit and knowledge continuity.
• Support internal audit and controls testing, particularly around SoD, workflow approvals, and financial process integrity.
• Manage the Application Management Services (AMS) vendor relationship — ticket triage and prioritisation, SLA/KPI monitoring, escalation management, and quality review of vendor-delivered fixes and enhancements.
• Act as the escalation and governance point between the business and the AMS partner, ensuring vendor delivery aligns with architectural standards and does not introduce technical debt or clean-core violations.
