In this role, you will be the primary technical authority for engineering, scaling, and optimizing our D365 F&O platform.

A central focus of this assignment is leading the end-to-end data synchronization and cross-app architecture between D365 F&O and D365 CRM/CE. The ideal candidate is an expert X++ developer who pairs elite integration engineering capabilities (Dual-write, OData, Azure Service Bus) with a strong functional understanding of corporate finance workflows to ensure unified data integrity across the organization.

Location: Toronto, ON (Hybrid – 1 day per week onsite, flexible)

Contract Duration: 6-month contract

Advantages
Strategic Technical Ownership: Direct the integration architecture for a massive cross-cloud deployment (F&O + CRM).

Highly Flexible Schedule: Enjoy supreme work-life balance with a flexible hybrid policy requiring only 1 day per week in the Toronto office.

High-Impact Multi-Track Scope: Expand your portfolio by handling complex parallel-development tracks and environment strategy for an enterprise-scale landscape.

Professional Continuity: Step into a critical role with an initial 6-month timeline and strong indicators for ongoing extension based on project phases.

Responsibilities
1. Advanced X++ Development & Customization
Design, code, and deploy secure, robust modifications within the D365 F&O ecosystem using X++ development and extensions-based customization.

Enforce strict architectural alignment with Microsoft’s standard update model, systematically defending against unnecessary core code invasive customizations by recommending out-of-the-box, configurable solutions.

Manage the full Software Development Life Cycle (SDLC), driving objects from initial requirements gathering through to technical design, code compilation, and post-go-live hypercare.

2. Multi-App Integration & Dual-Write Architecture
Architect, configure, and maintain highly integrated, bidirectional data streams between Dynamics 365 F&O and Dynamics 365 CRM / Customer Engagement (CE).

Act as the direct technical lead for configuring Dual-write maps, executing initial synchronizations, profiling latency bottlenecks, and debugging real-time payload failures.

Leverage advanced data frameworks including the Data Management Framework (DMF), Data Entities, OData endpoints, and custom REST/SOAP APIs.

Design and implement cloud messaging middleware utilizing Azure Integration Services (Logic Apps, Azure Service Bus, and Azure Functions).

3. Functional Alignment & Process Controls
Partner closely with corporate Finance and HR stakeholders to align technical data entities with core functional modules (General Ledger, Accounts Payable, Accounts Receivable, and Fixed Assets).

Implement rigorous data migration validation routines, ensuring historical and transactional datasets balance perfectly during multi-track system cutovers.

Audit and structure platform security roles, data sensitivity profiles, and compliance controls.

4. DevOps Governance & Environment Management
Govern the application lifecycle management (ALM) matrix utilizing Azure DevOps, managing code branching strategies, build definitions, and automated CI/CD pipelines.

Oversee environment lifecycle operations across Tier 1 (Development/OneBox) to Tier 2+ (Sandbox/UAT) topologies, coordinating flawless package deployment and code promotion schedules in parallel, multi-track development setups.

Qualifications
Core Experience: Minimum of 5+ years of hands-on technical development experience dedicated to Microsoft Dynamics 365 F&O (or Microsoft Dynamics AX 2012 with a heavy, demonstrable transition into F&O cloud systems).

Integration Specialization: Proven, hands-on track record of successfully implementing cross-app integrations using Dual-write, virtual tables, and the Dataverse infrastructure.

Development Stack: Advanced command of X++, .NET Framework, C#, MS SQL Server, and cloud-native Azure serverless technologies.

Methodology & Tooling: Deep familiarity with Azure DevOps release management, code promotion gates, and structural Agile/Waterfall hybrid delivery frameworks.

Collaboration Skills: Excellent written and verbal communication skills; comfortable presenting technical data constraints to non-technical business leaders and managing deliverables with external vendors.

Education: Post-secondary degree in Computer Science, Software Engineering, Information Technology, or a related technical discipline.
