Senior Software Engineer; Dynamics F-O

Senior Software Engineer – Dynamics F&O (Utrecht)

As a Senior Software Engineer (Dynamics F&O), you will be responsible for the development, enhancement, and optimization of our X++-based Independent Software Vendor (ISV) extension for Microsoft Dynamics 365 Finance & Operations.

The ideal candidate is a Senior Software Engineer (Dynamics F&O) / X++ Developer / Solution Architect who enjoys working on the core of the Dynamics 365 F&O platform, building generic and scalable frameworks, and ensuring that solutions integrate seamlessly with both Microsoft standards and third‑party extensions. They combine deep technical expertise with architectural thinking and a strong focus on maintainability, extensibility, and product quality.

The solution enables data from various external host systems to be integrated and written to both standard Finance & Operations entities and custom entities developed by third parties, implementation partners, or other ISVs
.

The focus of the role is to build and maintain a generic, configurable, and highly scalable integration framework that can support multiple customer environments and use cases.

You will operate at the core of the Dynamics 365 F&O platform, designing and implementing architecture that is robust, maintainable, and fully aligned with Microsoft best practices, extensibility standards, and the broader Dynamics ecosystem
.
