D365 F&O Integration Developer

About the job We're looking for a D365 F&O Integration Developer (X++ / Finance) to build and maintain the integrations that keep a major energy/power client's financial data flowing correctly into Dynamics 365 F&O. This is primarily a hands-on development role with a strong integration focus (X++ extensions, Azure integration services, and Finance/Accounts Receivable data). You'll own integration design end-to-end - working with finance, engineering, and Azure/infrastructure teams to keep invoicing, payments, and settlement data flowing cleanly into F&O. Your role with us: -You'll build integrations connecting internal operational systems with Dynamics 365 F&O. -You'll turn finance and integration requirements into robust, production-grade X++ extensions and Azure integrations. -You'll take ownership of integration design, delivery, resilience, and monitoring. What you'll actually do: Build business-critical integrations -Design and develop X++ extensions in D365 F&O using the extension model. -Build and maintain a robust Accounts Receivable integration covering customer invoicing, payments, settlement, and GL touchpoints. -Work across standard F&O integration patterns: Data Management Framework / data entities, OData, custom REST services, recurring integrations, business events, and the batch/package API. -Design and build the Azure side of each integration: Logic Apps, Service Bus (queues/topics), and Azure Functions. Make integrations resilient -Build in proper error handling, retries, and idempotency so integrations recover gracefully instead of failing silently. -Set up monitoring so issues surface early - before they hit Finance's ability to close the books. -Validate data consistency and recovery behaviour as volumes and integration scope grow. Keep delivery structured and moving -Collaborate with finance stakeholders, engineering teams, and the wider integration program. - Maintain clear integration designs, data flows, and error-handling documentation. -Plan integration delivery as the program scales into a second project starting next month that needs the same skillset. What we're looking for: -X++ development experience in D365 F&O (extension model). -Strong experience with standard F&O integration patterns : Data Management Framework / data entities, OData, custom (REST) services, recurring integrations, business events, batch/package API. -Hands-on experience with the Azure integration stack : Logic Apps, Service Bus (queues/topics), Azure Functions. -Solid grounding in the Finance domain , specifically Accounts Receivable (invoicing, payments, settlement) and GL touchpoints. -Strong grasp of integration design fundamentals : error handling, retries, idempotency, monitoring. Nice to have: -Experience with Dual-write / Dataverse, API Management, Event Grid. -Familiarity with bank/payment file formats (ISO 20022, SEPA). -Experience with Electronic invoicing / Electronic Reporting.
