This role provides dedicated Finance Operations representation across systems change, platform integrations, new business onboarding and M&A activity. It plays a critical role in protecting accounting integrity, preventing ledger anomalies, and ensuring that new or changed processes are implemented cleanly and sustainably into business‑as‑usual (BAU). Sitting within Finance Operations, the role works closely with the Business Unit (BU) Accounting team, who frequently encounter issues driven by system behaviour, integration failures and changes to accounting flows. Acting as a specialist investigator and subject matter expert, this role supports deep‑dive analysis of accounting issues and champions Finance Operations requirements in upstream design, change and integration discussions. This is a strategic yet hands‑on position, combining technical accounting insight with strong cross‑functional collaboration to ensure operational accounting processes remain robust through change.
