About The Role

The Accounting, Reporting & Treasury Lead is a hands‑on senior finance role responsible for leading all management and statutory financial reporting across Oritain's global entities, alongside treasury management, audit delivery, and finance policy development. Reporting to the Head of Finance Operations, Policy & Reporting and leading a team of three Management Accountants, you will be the custodian of financial governance and reporting excellence across the group.

• You will lead the preparation and submission of monthly, quarterly and annual accounts, regulatory filings and technical memos, and manage treasury operations including cash flow forecasting, banking relationships, liquidity management and investment oversight.
• You will design, implement and embed scalable finance policies and procedures, ensure group‑wide compliance with internal controls and external reporting standards, and lead audit delivery, coordinating effectively with external auditors to ensure timely, clean completion.
• Partnering closely with FP&A and wider finance teams, you will drive automation and system improvements across financial reporting and treasury operations, leveraging tools such as NetSuite, Power BI, and Excel, and championing the adoption of scalable AI solutions.
• You will also develop documentation and training materials, monitor operational KPIs, and lead and mentor your team of three with a focus on accountability, continuous improvement and technical excellence.

Skills & Experience

• You are a qualified accountant (ACA, ACCA or CIMA) with strong technical accounting, statutory reporting and treasury expertise, and a minimum of five years' experience in financial reporting, treasury or audit roles, ideally gained in a high‑growth or international environment.

• You have excellent attention to detail, an analytical mindset, and the communication skills to influence stakeholders and drive change.
• Experience managing and developing high‑performing teams is essential, as is the ability to thrive in a fast‑paced, evolving environment with a hands‑on approach.
