Senior Software Engineer (Dynamics F-O)

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.

• Design and develop scalable and maintainable solutions using X++ within Dynamics 365 F&O.
• Define and implement the technical architecture of the ISV extension.
• Ensure the solution is flexible enough to support various external host systems and customer‑specific requirements.
• Build reusable components and frameworks that minimize custom development and maximize configurability.
• Develop and enhance functionality that enables data integration between external systems and Dynamics 365 F&O.
• Create generic mechanisms for:
  • Data mapping
  • Transformation
  • Validation
  • Error handling
  • Logging and monitoring
• Ensure seamless interaction with:
  • Standard F&O entities
  • Custom entities developed by partners and third parties
  • Other ISV solutions within the Dynamics ecosystem
• Ensure the extension adheres to Microsoft’s extension model and upgrade‑safe development practices.
• Design solutions that remain compatible with future platform updates and releases.
• Optimize the application architecture to accommodate new entities and integrations without requiring significant redevelopment.
• Optimize code and architecture for:
  • High transaction volumes
  • Large datasets
  • Complex integrations
• Identify and resolve performance bottlenecks.
• Ensure the solution remains stable and scalable across multiple customer implementations.
• Provide technical guidance on architecture decisions and development standards.
• Collaborate with product owners, consultants, and developers to translate business requirements into technical solutions.
• Conduct code reviews and ensure adherence to development best practices.
• Contribute to the strategic roadmap of the ISV product.
• Develop and maintain technical documentation.
• Support testing, troubleshooting, and issue resolution.
• Ensure high levels of code quality, security, and maintainability.
