About the Company

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. 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.

Responsibilities

  • ● 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.

Requirements

  • ● 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.
  • ● 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.
