Lead Solutions Architect - D365

About The Role

The D365 Solution Architect plays a key role in shaping how we use Microsoft Dynamics 365 across Finance&Operations, Supply Chain, WMS and Azure. They’re responsible for the end‑to‑end design of our solutions, making sure everything hangs together — from functionality and integrations through to data, security and long‑term supportability.

This role keeps us aligned with Microsoft’s roadmap, sets clear architectural standards and cuts out unnecessary complexity. The focus is on building solutions that are scalable, reliable and ready for One Version — not just today, but for the long term.

Working closely with Functional and Technical Consultants, Integration Engineers, Test Leads, Enterprise Architects and our business teams, the Solution Architect helps create a D365 platform that’s secure, cost‑effective and built to support the way AO operates.

Here's What You Can Expect To Be Doing

As D365 Solution Architect, you own the end‑to‑end architecture across Finance&Operations, Supply Chain, WMS and Azure. You set the direction, define clear design standards and make sure solutions are simple, scalable and aligned to Microsoft’s roadmap — with minimal customisation and full One Version readiness.

You govern configuration, extensions, integrations and ISVs, balancing the right use of D365, Power Platform and third‑party tools while keeping technical debt under control. You ensure integrations are robust, data flows are reliable and the platform can handle high‑volume, business‑critical workloads.

You provide architectural oversight across environments, releases, data migration and cutover, making sure the platform is resilient, secure and operationally ready. Working closely with delivery teams, enterprise architecture, Microsoft and vendors, you guide decisions, challenge complexity and help build a D365 platform that’s cost‑effective, secure and built to support how AO runs — especially at peak.
