We're excited to share an opportunity for an experienced and motivated finance professional to join Ordnance Survey as our Senior Management Accountant. This is a pivotal leadership role within Central Finance, responsible for leading the management accounting and reporting team, ensuring the delivery of high-quality monthly and quarterly reporting. The role offers an excellent opportunity to shape and improve financial processes, drive continuous improvement and automation, and play a key part in delivering a modern, high-performing finance function.
Working closely with Finance Business Partners, Technical Finance, FP&A and Finance Operations, you'll provide leadership across the financial close process while helping to ensure that financial information and insight support effective decision-making across OS.
About the role
As Senior Management Accountant, you'll lead and develop a team of management accountants and finance professionals, creating a culture of accountability, collaboration and continuous improvement.
You'll be accountable for the integrity of management reporting, the effective operation of financial controls and reconciliations, and the successful delivery of monthly and quarterly close processes. Beyond reporting, you'll be expected to identify opportunities to simplify, standardise and automate finance processes, helping to build greater efficiency, control and insight across the organisation.
This is an ideal opportunity for someone who enjoys combining strong technical accounting expertise with people leadership, process improvement and stakeholder engagement.
Key Responsibilities
Leadership and Team Development
- Lead and develop the Management Accounts team by creating a high-performing, inclusive and accountable culture that delivers high-quality outcomes. You'll provide clear direction and priorities, support professional growth through coaching and development, and build team resilience through effective succession planning, cross-training and knowledge sharing
Management Accounting and Reporting
- Take ownership of the monthly and quarterly reporting cycle, ensuring the delivery of accurate, timely and insightful management information. You'll oversee the preparation and review of management accounts, manage reporting deadlines and dependencies, lead financial performance reviews, and maintain oversight of all core management accounting activities to ensure robust financial control and reporting integrity.

Continuous Improvement and Transformation
- Drive continuous improvement across the Management Accounts function by simplifying, standardising and automating processes. Working closely with finance and technology teams, you'll lead initiatives that enhance efficiency, reporting quality and insight, while developing and delivering a roadmap that strengthens systems, processes and ways of working.
