Microsoft Business Central Senior Developer

AL Development & Customization

• Design, write, test, and deploy AL extensions for Dynamics 365 Business Central using Visual Studio Code and the AL Language extension
• Build custom tables, pages, codeunits, reports, queries, and XMLports following Microsoft extension model best practices
• Develop event-driven customizations using publisher/subscriber patterns to maintain upgrade safety and avoid direct base application modifications
• Write and optimize AL procedures and triggers, applying proper separation of business logic from UI and data layers
• Manage extension dependencies, app manifests (app.json), and versioning across development, staging, and production environments

Business Central Architecture & Schema

• Demonstrate fluency with Business Central's core table schema — including G/L Entry, Item Ledger Entry, Customer/Vendor Ledger Entries, Posted Documents, Assembly and Production Orders, and related posting routines
• Navigate and apply Business Central's page and page extension framework, including ListParts, FactBoxes, Role Centers, and API pages
• Understand and work within Business Central's permission model, profiles, and configuration packages
• Design data models that align with Business Central's relational schema patterns and avoid breaking changes to core application flows
• Apply knowledge of Business Central's posting codeunits and journal mechanics when building finance or inventory customizations

Integrations & APIs

• Build and maintain integrations using Business Central's OData v4 and REST APIs, custom API pages, and web services
• Develop and consume integrations with external platforms including Power Platform, Azure services, third-party SaaS tools, and EDI systems
• Design integration patterns using Azure Logic Apps, Azure Functions, or direct API-to-API calls as appropriate for the use case
• Implement robust error handling, retry logic, and logging for all integration touchpoints

Collaboration & Delivery

• Partner with functional consultants to translate business requirements into sound technical designs before committing to development
• Participate in solution design reviews, code reviews, and sprint ceremonies as part of an Agile delivery team
• Document technical designs, data flow diagrams, and post-deployment configuration steps for hand-off and support
• Support testing cycles including unit testing, UAT facilitation, and post-go-live stabilization
• Provide Level 2/3 technical support for Business Central issues escalated beyond functional team resolution

Experience

• 5+ years of hands-on AL development experience in Microsoft Dynamics 365 Business Central (not solely legacy C/AL in NAV)
• Demonstrable experience building production-grade BC extensions — portfolio, GitHub repo, or customer references required
• Experience working across multiple Business Central functional areas: Finance, Inventory, Sales, Purchasing, or Manufacturing
• Exposure to Business Central SaaS (cloud) deployment; on-premises experience a plus but cloud-first mindset required

Preferred Qualifications

• Microsoft Certified: Dynamics 365 Business Central Developer Associate (MB-820) or equivalent certification
• Experience with legacy C/AL and upgrade migrations from NAV to Business Central
• Familiarity with Business Central's Manufacturing module (Production Orders, Routings, BOMs)
• Experience with Warehouse Management and Advanced Warehousing configurations
• Background in multi-company, multi-currency, or multi-entity Business Central environments
• Knowledge of AppSource publishing process and Microsoft's technical validation requirements
• Experience with Business Central Container-based development (BcContainerHelper / Docker)
