The Role:

We are looking for a Senior Business Central Developer on behalf of our client to lead the technical design, development, and customization of core Microsoft Dynamics 365 Business Central solutions. In this role, you will take operational ownership of complex ERP extensions—architecting robust AL codebases, integrating third-party systems via web services, and optimizing database performance across multi-tenant cloud environments.

What we are looking for:

• 5+ years of dedicated software development experience with Dynamics 365 Business Central (and legacy Dynamics NAV), featuring expert-level proficiency in AL language, custom page/report extensions, codeunits, and event subscribers.

• Strong functional and technical command of standard Business Central modules, including Finance (GL, AP, AR), Supply Chain, Inventory, Purchasing, and Sales.

• Extensive experience connecting Business Central with external systems, CRMs, and e-commerce platforms using RESTful web services, OData, JSON, and OAuth2 authentication.

• Daily practice authoring automated unit and integration tests using the AL Test Framework, utilizing test isolation and mocks to ensure upgrade stability.

• Proven experience maintaining source code, versioning, and automated build pipelines using GitHub Actions, AL Go for GitHub, or Azure DevOps.

• Deep understanding of SQL Server fundamentals, Business Central telemetry, index tuning, and performance profiling to eliminate lockups and slow-running queries.

Nice-to-have:

• Practical experience navigating Microsoft AppSource validation workflows and technical compliance checks.

• Familiarity with the broader Microsoft Power Platform (Power Apps, Power Automate, Power BI) and Dataverse synchronization.

• Exposure to Azure cloud services (Azure Functions, Azure Logic Apps, Azure Key Vault).

• Background in migrating legacy C/AL codebases (Dynamics NAV) to modern AL extensions.

Responsibilities:

• Design, build, and maintain scalable Business Central extensions in AL using event-driven architectures to customize ERP business logic cleanly.

• Architect secure web service integrations between Business Central and external applications (ERPs, CRMs, banking networks, e-commerce storefronts).

• Analyze system logs and telemetry using Business Central performance profilers and Application Insights to resolve locking, slow requests, and resource bottlenecks.

• Establish and manage automated build, test, and release workflows using GitHub Actions and AL Go across development, staging, and production environments.

• Enforce strict coding standards, conduct peer code reviews, and ensure codebases strictly adhere to Microsoft's technical guidelines for cloud upgrades and AppSource publication.
