Business Central / AL Developer (ID: 4061)

Mid-to-Senior Business Central / AL Developer

About the Role

As a Mid-to-Senior Business Central / AL Developer, you will own the expansion of the automated test suite for an existing production-grade Microsoft Dynamics 365 Business Central extension. You will work on bringing an existing productive Business Central extension to bank-grade production quality, including security validation and formal user acceptance testing.

The role involves an approximate allocation of 60% development and 40% QA.

Responsibilities

• Develop and enhance Business Central extensions using the AL programming language
• Own the expansion of the automated test suite for an existing production-grade Microsoft Dynamics 365 Business Central extension
• Raise automated test coverage substantially across an existing codebase using the Business Central test framework
• Develop logging and audit-trail capabilities, including PII masking and immutable logging
• Implement observability and monitoring using Azure Monitor
• Develop and harden CI/CD pipelines and deployment automation using GitHub Actions and AL-Go for GitHub
• Implement infrastructure as code using Azure services and ARM templates or comparable technologies
• Work on Azure Key Vault integration and secure management of application secrets and configuration
• Work on the configuration and administration interface, including clear separation between sandbox and production environments
• Develop the white-label branding framework and prepare the Business Central extension for AppSource packaging
• Support quality assurance activities
• Contribute to bringing the extension to bank-grade production quality
• Work with integrations including corporate bank APIs using mTLS and OAuth2, ISO 20022 camt processing and third-party PSD2 aggregation

Technical Environment

• Codebase of approximately 265 AL objects and 40,000 lines of code across the current Business Central major version and an older on-premise BC13 backport track
• Existing automated tests comprising approximately 165 tests across 22 test files with current approximately 40% test coverage
• GitHub, Jira, Azure DevOps and approximately 19 existing GitHub Actions workflows

Required Experience

• Strong hands-on experience with Microsoft Dynamics 365 Business Central and AL development
• Proven experience developing and maintaining Business Central extensions in production environments
• Demonstrable experience with the Business Central automated test framework and increasing test coverage on an existing codebase
• Strong experience with test automation and quality assurance within Business Central development projects
• Hands-on experience with GitHub Actions and preferably AL-Go for GitHub
• Experience with Azure services including Azure Key Vault and Azure Monitor
• Experience with infrastructure as code using ARM templates or comparable technologies
• Strong understanding of CI/CD, deployment automation and pipeline hardening
• Experience working with production-grade software where security, reliability, testing and release quality are critical
• Disciplined documentation practices, with the ability to produce technical documentation and architecture/development decisions throughout the engagement
• Professional written and spoken English

Key Abilities

You should possess the ability to:

• Take ownership of QA and automated testing rather than limiting your contribution to manual testing
• Analyse an existing Business Central codebase and identify opportunities to increase automated test coverage
• Design and implement reliable automated tests for Business Central functionality
• Build maintainable CI/CD workflows and improve existing deployment pipelines
• Implement secure logging, audit trails and PII masking
• Configure monitoring and observability for production-grade applications
• Work with secure authentication and integration mechanisms such as OAuth2 and mTLS
• Handle certificates, secrets and security-sensitive configuration appropriately
• Separate sandbox and production configurations and deployment processes
• Prepare Business Central extensions for AppSource technical validation and packaging
• Perform or support performance testing and production-readiness activities
• Work independently while maintaining clear technical documentation and communicating decisions effectively
• Work full-time on a dedicated basis without parallel project allocation
• Maintain continuity throughout the engagement and participate in a documented handover if substitution is required
• Work within EU/EEA data-handling requirements and use client-provided environments for development, storage and processing
• Maintain confidentiality and comply with NDA, IP assignment and non-subcontracting requirements
• Maintain at least six hours of working-time overlap with Central European Time

What We Bring to the Table

• Established Jira-based backlog management with defined epics and stories
• Documentation templates, technical standards and an architecture decision record process
• An opportunity to work on a production-grade Business Central solution involving Azure, banking APIs, secure authentication and automated quality assurance
• Potential follow-on maintenance work following successful completion of the delivery engagement
• A technically focused environment with significant scope for improving automated testing, observability, infrastructure automation and production readiness
