OIC (Oracle Integration Cloud) Developer

Our client is seeking an experienced Oracle Integration Cloud (OIC) contractor to serve as a long-term integration specialist supporting a multi-year, phased migration from SAP ECC to Oracle Fusion ERP. The contractor will design, enhance, and support OIC-based integrations across multiple business modules, beginning with Finance and extending to additional SAP ECC domains as they are migrated to Oracle Fusion over the next 2-3 years. This is a hands-on delivery role focused on integration design, development, testing, and production support. Responsibilities:

• Analyze existing SAP ECC integrations and interface architectures to define integration patterns and migration approaches within Oracle Integration Cloud (OIC)
• Design, develop, and enhance OIC integrations to support ERP coexistence and phased migration from SAP ECC to Oracle Fusion ERP
• Build and modify OIC integrations using REST, SOAP, file-based, and event-driven patterns, leveraging OIC adapters where appropriate
• Develop and maintain OIC integration mappings using XSLT, JSON, XML, and canonical data models to ensure reusable and scalable integration design
• Implement and manage coexistence, parallel-run, and cutover integration scenarios in OIC between SAP ECC and Oracle Fusion
• Configure and maintain OIC error handling, tracking, logging, monitoring, and performance optimization to ensure integration reliability and SLA compliance
• Collaborate with functional, SAP, Oracle Fusion, and infrastructure teams to translate business and system requirements into OIC-based integration solutions
• Provide ongoing OIC operational support, enhancements, and governance as additional SAP ECC modules and interfaces are migrated over time

• 5+ years of hands-on Oracle Integration Cloud (OIC) experience with end-to-end ownership of integration architecture, development, deployment, and support
• Strong experience designing and implementing OIC-based integrations for Oracle Fusion ERP, including support for phased migrations, coexistence, and hybrid landscapes
• Solid understanding of SAP ECC integration mechanisms, including data models, IDocs, RFCs, and legacy interfaces, from an integration-consumer perspective
• Deep expertise in REST and SOAP services, and data transformation using JSON, XML, and XSLT within OIC
• Hands-on experience with OIC adapters, packages, integration patterns (app-driven, scheduled, event-based), and connectivity agents
• Proven ability to design reusable, scalable, and supportable OIC integrations, including canonical models and standard error-handling frameworks
• Experience operating independently in a long-term contractor or lead integration role, managing deliverables with minimal oversight
• Strong communication skills with the ability to translate business and functional requirements into OIC integration solutions and collaborate effectively with cross-functional teams
• Prior experience leading or supporting SAP ECC to Oracle Fusion ERP migrations with clear ownership of the integration layer using Oracle Integration Cloud (OIC)
• Hands-on experience designing and supporting ERP coexistence, parallel-run, and phased migration integration strategies within OIC
• Working knowledge of Oracle Cloud Infrastructure (OCI) related to integration deployments, security, networking, and connectivity
• Broad understanding of end-to-end ERP business processes across multiple domains (e.g., Finance, SCM, Procurement, Order Management, HCM) to support cross-functional integrations
• Proven experience providing production support, post-go-live stabilization, and ongoing optimization for enterprise ERP integrations built on OIC
