Oracle Retail Developer: Retail Systems & API Integration

We're modernising our Oracle Retail landscape across Thailand, Cambodia, and Myanmar and need a hands-on developer who is equally strong on Oracle Retail internals and modern API/integration development . You'll work across merchandising, invoice, and store systems building and supporting the interfaces that connect Oracle Retail to upstream/downstream platforms, including our Oracle Fusion ERP and in-store applications. This is a builder role, not a maintenance-only role. You should be comfortable owning a problem end-to-end: reading the business requirement, designing the integration, writing the code, and supporting it in production. Candidate Profile A self-driven Oracle Retail developer who can move fluidly between deep Oracle Retail/PL/SQL work and modern Java/API integration . You understand retail data flows well enough to design solutions, not just code to spec, and you can keep critical production processes stable in a multi-country retail environment. What You'll Do Develop, enhance, and support Oracle Retail modules (RMS/Merchandising, ReSA, ReIM, RPM, SIM, RIB) customizations, batch programs, and interfaces. Build and maintain integrations between Oracle Retail and external systems using REST APIs, RIB, file/SFTP-based interfaces, and middleware patterns . Develop API services and microservices in Java / Spring Boot , handling JSON/XML payloads, error handling, and retries. Write and tune PL/SQL packages, procedures, triggers, and batch jobs; optimise SQL for large-volume retail data. Support core retail flows: items, suppliers, POs, transfers, stock ledger, pricing, deals, invoices, and financial postings into ERP. Troubleshoot production issues across batches, interfaces, and APIs including data discrepancies between Retail and Finance. Produce technical specs, unit test evidence, and deployment/support documentation. 5 to 10 years in IT, with solid Oracle Retail development experience in at least one of: RMS/Merchandising, ReSA, ReIM, RPM, SIM. Strong Oracle SQL and PL/SQL , including performance tuning and Oracle DB objects. Hands-on API integration development Java, Spring Boot, REST, JSON/XML; ideally a microservices mindset. Experience with Oracle Retail batch processing and interface development with upstream/downstream systems. Working knowledge of Unix/Linux shell scripting . Good grasp of retail business processes (item creation, POs, sales audit, inventory, invoices, pricing, stock ledger, financial integration). Ability to debug interface/batch/API failures independently and communicate clearly with cross-functional teams. Nice-to-Have Oracle Retail Cloud / OCI exposure. RIB, BI Publisher / BIP, or OIC experience. Integration with Oracle Fusion / EBS financials. Tooling: Postman, SQL Developer / TOAD, Control-M/UC4/AppWorx, Git, WinSCP/Putty. Containers (Docker/Kubernetes) and CI/CD familiarity. Basic frontend (React/HTML/CSS) for internal tooling a plus, not a requirement.
