About The Position

The Howard de Walden Estate (HdWE) is embarking on a business-wide modernisation programme, to revitalise ways of working, data, systems and processes. Project Elevate has been initiated to replace the current Property Management and Accounting system (MRI Platform X), in place for nearly three decades. The programme will deliver a unified, scalable and supportable SaaS platform covering finance, property management, procurement, project accounting and reporting. It is a strategically important initiative that will fundamentally change how the organisation operates and how colleagues interact with core systems. Project Elevate is a multi‑year transformation programme to implement Microsoft Dynamics 365 Finance & Supply Chain Management as the organisation’s core ERP platform, integrated with existing Microsoft Dynamics 365 Customer Engagement and M-Files Document Management applications. The project will also incorporate specialist Independent Software Vendor (ISV) solutions, including Yavica’s FlexProperty and SignUp’s ExFlow products. The D365 F&O System Administrator role is permanent, reporting to the Head of IT. The role forms part of the core team supporting the delivery of Project Elevate and the long‑term operation of the ERP platform. The role will provide in‑house ownership of system administration, security, access control and platform governance, supporting both the implementation phase and ongoing business‑as‑usual operation post go‑live. This position offers the opportunity to play a key role in a business‑critical transformation programme and to take long‑term ownership of a modern SaaS ERP platform that underpins core finance and operational processes across the organisation.
