As part of this critical change initiative, an experienced Data Conversion Manager is required to lead the migration of financial data, documents, images and associated records into the new environment. Your new role Reporting into the finance transformation programme, you will take ownership of the end-to-end data conversion workstream, ensuring all migration activities are delivered in a controlled, auditable and fully reconciled manner. This is not a traditional project management role. The successful candidate will be expected to combine strategic oversight with hands-on delivery, taking an active role in data extraction, mapping, validation, reconciliation and conversion activities. Working closely with Finance SMEs, technical teams, project stakeholders and implementation partners, you will lead the discovery of source systems, define source-to-target mappings, manage data quality issues, oversee exception management and support testing, cutover and post-migration activities. The programme includes the migration of significant volumes of finance-related data and documentation, including invoice images, purchase order records, goods received notes, remittance advice documents and supporting attachments. You will ensure all migrated records can be traced and reconciled back to source systems while maintaining robust governance, audit trails and project documentation throughout the engagement.
