Dynamics 365 F&O Developer

As part of our client Microsoft Dynamics 365 program, the Finance & Operations (F&O) Developer will build the internal technical capability needed to support and extend the ERP platform. Working closely with key users across Finance, Supply Chain, Procurement, and Operations, this role translates business needs into clearly documented technical requirements and delivers the X++ customizations, extensions, reports, and integrations that support them. This is a hands-on, in-house role with long-term ownership of the F&O solution — from requirements capture through development, testing, deployment, data migration support, and ongoing optimization.
