Summary

What you'll do

As our Finance Systems Accountant, you will be the subject-matter expert for our legacy finance systems, including SunSystems 6.4, Infor Query & Analysis 11.3, Professional Advantage products and PTX Cloud. You will take responsibility for keeping the SunSystems platform reliable, controlled and audit-ready throughout its remaining operational life.

Working within our specialist Finance Systems Team and reporting to the Head of Finance Systems, you will partner closely with colleagues across Finance and IT. This role sits at the heart of our transition to Microsoft Dynamics 365 Finance and Operations, supporting month-end and year-end close, external audit, data migration and the eventual archiving and decommissioning of our legacy systems.

Your work will help ensure that the organisation continues to report, pay suppliers and close its books accurately while moving to a new finance platform. You will directly support accurate financial reporting, strong controls and audit readiness across an organisation managing approximately 70,000 homes.

How you'll do it

• Administer SunSystems and its associated reporting and add-on tools, maintaining user access, accounting periods, chart of accounts and cost-centre structures to agreed standards.
• Monitor and reconcile data flowing between the legacy ledger, Dynamics 365 Finance and Operations and feeder systems, including rents, cash, payroll and agency payments.
• Investigate and resolve interface, posting and reconciliation errors before they affect month-end or year-end close.
• Support the delivery of the finance reporting calendar, ensuring journals and reconciliations are completed accurately, evidenced and on time.
• Provide reliable reporting, data extracts and ad-hoc analysis to Finance leaders, business partners and analysts using SunSystems reporting and query tools.
• Support internal and external audit by providing appropriate system access, extracts, control evidence and reconciliations to deadline.
• Maintain alignment between legacy finance structures and the agreed Dynamics 365 chart of accounts, financial dimensions and master-data standards.
• Support the extraction, mapping, validation and reconciliation of balances as data is migrated from legacy systems to Dynamics 365.
• Log and resolve operational issues within agreed service levels, identifying and addressing root causes to reduce manual effort and strengthen controls.
• Document system knowledge through clear runbooks, procedure notes and reconciliation guides, helping to reduce key-person dependency.
• Work with IT and external suppliers to deliver changes safely through agreed change-control, risk and governance processes.
• Help ensure electronic payments are processed accurately, securely and on time.
