Nat Cen is looking for a Systems Accountant to support the maintenance, development and optimisation of its finance systems, ensuring they remain accurate, reliable and fit for purpose. This is a hands-on systems role sitting at the intersection of Finance, IT and operational users, with responsibility for finance systems support, process improvement, automation and reporting development.

A major focus of the role is ownership of the purchase order system and its workflows, together with SQL-based automation and finance systems improvement. The successful person will be comfortable working in the backend of finance systems, troubleshooting issues, maintaining documentation, supporting users and identifying ways to reduce manual effort through system enhancement and automation.

This is not a pure management accounting role. It is best suited to someone who combines finance systems understanding with strong SQL capability, logic, attention to detail and a practical approach to solving problems.

Experience of finance or ERP systems, reporting, controls and process improvement will be important, and exposure to project-based or commercial environments may help someone get up to speed more quickly.

• Lead the maintenance, administration and continuous improvement of Nat Cen’s finance systems so they remain accurate, reliable and useful to the business.
• Act as a key point of contact for finance systems queries, supporting both finance and non-finance users and helping resolve issues in a timely, practical way.
• Own and manage the purchase order system, including workflows, approval hierarchies, controls and improvements linked to finance policy and process efficiency.
• Design, develop and maintain SQL stored procedures, views and scripts to automate financial processes including month-end, data extraction, uploads and reconciliations.
• Support stronger reporting, reconciliations, analysis and data integrity through effective use of finance systems and backend data.
• Work closely with Finance, IT and wider stakeholders on system upgrades, enhancements, testing, process improvement and future automation opportunities.

• Strong MS SQL experience, including stored procedures, query optimisation and data transformation.
• Good understanding of accounting principles, financial processes, controls and reporting requirements, especially around general ledger, purchase orders and month-end close.
• Experience supporting, maintaining, implementing or upgrading finance or ERP systems.
• Strong systems mindset, with logic, attention to detail and confidence working with system data and backend workflows.
• Ability to investigate issues, improve processes and deliver practical automation that reduces manual effort and improves reporting quality.
• Comfort working across Finance, IT and wider business stakeholders, with clear communication and a service-oriented approach.

Why join Nat Cen?

This role offers the opportunity to take ownership of finance systems improvement in a values-led organisation, with real scope to strengthen controls, streamline finance operations and improve how finance data is used across the business. It will suit someone who enjoys problem solving, systems thinking and making processes work better.
