Financial Accountant – SAP S/4HANA Implementation

Contract until end of year (likely extensions)

We are seeking an experienced Financial Accountant with proven SAP S/4HANA implementation experience to support a number of strategic finance transformation programmes.

This role will act as the Finance SME within project delivery teams, ensuring that finance requirements, accounting treatments, reporting needs and control frameworks are effectively designed, tested and implemented within new systems and processes.

The successful candidate will have previous hands-on experience supporting or delivering SAP S/4HANA implementations within a finance environment and will be comfortable working alongside project teams, business analysts, developers, testers and key finance stakeholders.

This is a project-focused role and not a traditional operational accounting position. The successful candidate must be able to contribute immediately, bringing practical experience gained from previous finance system implementation programmes.

Key Responsibilities

• Act as the Finance SME within SAP S/4HANA and wider finance transformation programmes.
• Support the definition and documentation of finance business requirements.
• Review and challenge proposed system solutions to ensure accounting and reporting requirements are met.
• Work closely with Business Analysts, Developers and Project Teams throughout the project lifecycle.
• Assess the impact of system changes on downstream finance processes, reporting and controls.
• Perform and support User Acceptance Testing (UAT), ensuring financial processes and controls operate as intended.
• Prepare test scenarios, execute testing and support issue resolution through to completion.
• Support finance data migration activities, including validation, reconciliation and sign-off processes.
• Develop future-state process maps, operating procedures and training materials.
• Deliver knowledge transfer and training to finance stakeholders where required.
• Provide regular updates and recommendations to Finance leadership and project governance groups.
• Qualified or part-qualified ACCA, CIMA or ACA.
• Previous experience working on at least one SAP S/4HANA implementation programme within a finance function.
• Strong understanding of General Ledger, Financial Reporting, Balance Sheet Reconciliations and Financial Controls.
• Proven experience supporting User Acceptance Testing (UAT).
• Experience of finance data migration, reconciliation and validation activities.
• Experience gathering and documenting business requirements.
• Strong stakeholder management skills with the ability to work across Finance, Technology and third-party suppliers.
• Multiple SAP S/4HANA implementation projects.
• SAP FI, AP and AR module knowledge.
• Experience within finance transformation or ERP implementation programmes.
• Experience supporting cutover and go-live activities.
• Process mapping and business readiness experience.
