JOB DESCRIPTION

Integration Technical Lead

D365 Finance & Operations Implementation | Retail Supermarket Chain

1. General Information

Integration Technical Lead

Reports To

Project Director / CIO

2. Role Purpose

The Integration Technical Lead is responsible for designing, directing the development, testing, and operating the full integration landscape connecting D365 F&O to all core systems: POS/mPOS, WMS, TMS, E-commerce, Payment Gateway, Loyalty/CRM, E-invoice, BI/Data Warehouse, and Supplier EDI.

3. Key Responsibilities

A. Integration Architecture & Design

Design the overall Integration Blueprint for D365 F&O within the retail ecosystem, covering: API Gateway & Management layer, Integration Platform (Azure Integration Services / iPaaS), Event Bus (Kafka / Azure Event Hub / Service Bus), and EDI layer for supplier communication.

Build a detailed Integration Catalog for all integration points (1530+ interfaces): source/target, pattern, frequency, volume, and SLA.

Design appropriate integration patterns for each retail use case:

Price distribution POS, E-commerce

Publish-Subscribe (real-time)

Event-driven via Kafka/Service Bus

Sales posting POS ERP GL

Batch (EOD + hourly summary)

50K transactions/store/day

Inventory sync WMS ERP POS

Near real-time (15 min interval)

CDC or scheduled polling

Payment authorization POS Gateway

Request-Reply (synchronous)

<200ms response, PCI-DSS compliant

Supplier PO / ASN / Invoice

EDI (Event)

EDIFACT or API-based

E-invoice ERP Tax Authority

Synchronous API

Viettel/VNPT/BKAV integration

GL posting BI/DW

CDC / Batch

Hourly/Daily incremental load

Design Master Data Management (MDM) strategy: golden record sources, sync rules, data steward workflow.

B. D365 F&O Integration Development

Direct the development and configuration of D365 F&O Data Entities and Data Management Framework (DMF) for inbound/outbound integrations.

Design and oversee the deployment of OData APIs, Custom Services, and Business Events on D365 F&O.

Configure Dual-write between D365 F&O and Dataverse (where D365 CE/CRM integration applies).

Review and approve X++ extensions for custom integration logic: data transformation, validation rules, error handling.

Design and deploy recurring integrations via DMF: import/export packages and scheduled batch jobs.

Manage D365 F&O Virtual Entities and Azure Synapse Link for near real-time analytics integration.

C. Azure Integration Services

Azure Logic Apps

Workflow orchestration for complex integration flows

Azure Service Bus

Message broker for async, pub-sub, and queue-based patterns

Azure Event Grid

Event routing for D365 F&O Business Events

Azure API Management (APIM)

API gateway: rate limiting, authentication, monitoring, versioning

Azure Functions

Lightweight transformation, data enrichment, custom logic

Azure Data Factory

Batch ETL/ELT for data warehouse integration

Azure Event Hub

High-throughput event streaming (POS transactions, IoT)

Implement error handling patterns: dead letter queue, automated retry (exponential backoff), alerting, and manual review workflow.

Design monitoring & alerting on Azure Monitor / Application Insights for all integration flows.

D. API Design & Standards

Design and document APIs per OpenAPI 3.0 specification.

Apply RESTful API design standards: naming conventions, pagination, sorting, filtering, uniform error response format with correlation ID, and URL-based versioning (/v1, /v2).

Implement API security: OAuth2/JWT for consumer auth, mTLS for system-to-system, API key management.

Ensure all APIs are idempotent safe to retry without creating duplicate records.

E. EDI & Supplier Integration

Design and implement EDI integration with suppliers: EDIFACT/X12 for Purchase Orders, ASN, Invoices, and Price Catalogs.

Coordinate supplier onboarding: capability assessment, technical setup (VAN/AS2/API), mapping, testing, pilot, and go-live.

Deploy e-invoice integration with Vietnamese e-invoice providers (Viettel, VNPT, BKAV).

F. Integration Testing & Quality Assurance

Build and execute an Integration Test Plan: unit, integration, end-to-end, and performance testing.

Design test scenarios for all integration points: happy path, negative scenarios, error handling, volume/load testing (peak: Tet, Black Friday), and failover/DR scenarios.

Integration SLA Targets:

API Success Rate

> 99.9%

API Response Time (p95)

< 200ms

Message Processing Latency

G. Integration Operations & Support

Build an Integration Operations Runbook: troubleshooting guides, escalation procedures, and monitoring dashboards.

Design comprehensive monitoring & alerting: real-time dashboards, proactive alerting for queue depth and API error rates, and correlation ID-based end-to-end transaction tracing.

Support hypercare (812 weeks post go-live): monitor integration performance, resolve incidents, optimize throughput.

Conduct knowledge transfer to internal IT operations team.
