AX DEVELOPER JOB DESCRIPTION

An AX Developer writes, customizes, and supports code inside Microsoft Dynamics AX and D365 Finance & Operations - not just any ERP, but a platform where PCI compliance and SDLC governance directly shape how every change gets written and promoted. That scope is narrower and more accountable than general .NET work. Enterprise teams depend on this developer to own the full change cycle: from X++ customization through environment promotion, integration design, and post-live support. The role carries individual ownership, not shared sprint output.

As the AX Developer, you own the design, build, and lifecycle management of Dynamics AX and D365 FO customizations that keep enterprise operations running reliably and securely. You work within a cross-functional IT team alongside functional analysts and business stakeholders, with your output directly governing what reaches production environments.

Career Impact: Hands-on ownership of X++ development and full-lifecycle D365 FO implementations builds the kind of platform-specific expertise that commands a premium in the Microsoft ERP talent market.

Business Impact: The enterprise workflows you customize - from warehouse management to financial reporting - are mission-critical processes; defects or delays here surface immediately in operations.

Growth Opportunity: Experience spanning AX 2012 through D365 FO migration positions you for a natural progression into ERP Architect or Solutions Lead roles as cloud-platform adoption accelerates.

• Design and implement new features and module customizations in Dynamics AX and D365 FO using X++ and MorphX.
• Develop and maintain web services, integrations, and supporting applications within the Microsoft enterprise stack.
• Review code changes submitted by team members and provide structured technical feedback to maintain standards.
• Coordinate with functional analysts and business users to translate requirements into technical specifications and documentation.
• Manage environment promotion of code changes from development to testing using XPO, model files, or equivalent techniques.
• Conduct unit testing and support user-acceptance testing to validate that delivered solutions perform accurately under business conditions.
• Mentor junior developers on architecture decisions, secure coding practices, and platform-specific development patterns.
• Support system upgrades, data migration activities, and post-live troubleshooting to maintain platform stability.

• Bachelor's degree in Computer Science, Information Systems, or equivalent work experience.
• 4 or more years of Dynamics AX or D365 Finance & Operations development experience, with demonstrated X++ implementation work.
• Proficiency in X++ and MorphX IDE for building and customizing ERP modules and workflows.
• Working knowledge of Microsoft SQL Server, T-SQL stored procedures, and relational database design principles.
• Experience with .NET and C# for developing supporting services and integrations within the Microsoft stack.
• Familiarity with SSRS report development and deployment within Dynamics AX environments.
• Demonstrated ability to follow SDLC frameworks, including code review practices, documentation standards, and environment governance.
• Understanding of secure coding principles and compliance requirements relevant to enterprise ERP systems.

• Experience with D365 FO migration from AX 2012, including module parity assessment and cutover planning.
• Exposure to SharePoint, enterprise portal development, or eServices integration within a Dynamics environment.
• Certification in Microsoft Dynamics AX or D365 Finance & Operations programming.
• Familiarity with MS Sure Step implementation methodology or equivalent structured ERP delivery frameworks.

• Code defect rate per sprint cycle, measuring the stability of delivered X++ customizations.
• Environment promotion cycle time, tracking how efficiently changes move from development to QA.
• User-acceptance testing pass rate on first submission, reflecting solution accuracy against business requirements.
• Post-live incident volume attributable to custom code, indicating long-term reliability of delivered work.
• Documentation completeness score, assessed at each release milestone against team standards.
• Typical tools: ERP development IDE (commonly Visual Studio with MorphX); version control (commonly TFS, VSTS, or Git); reporting (commonly SSRS).

• Base Salary Range: $95,000 to $130,000 annually, depending on seniority and location
• Bonus: Annual performance-based bonus, typically 5% to 10% of base salary
• Equity: Stock options or RSUs offered at larger organizations; less common at mid-market
• Health Benefits: Medical, dental, and vision coverage; employer contributes to premiums
• PTO: 15 to 20 days annually, plus standard public holidays
• Common Perks: Remote or hybrid flexibility, Microsoft certification reimbursement, continuing education budget
