OIC INTEGRATION LEAD / DEVELOPER

About the Role We are looking for a hands-on Oracle Integration Cloud (OIC) Lead / Developer who acts as both an integration lead and a practical builder. This is deliberately not an architecture-only position; you will own the technical interface catalogue, author MD.070 designs, build approved OIC integrations, secure and monitor interfaces, support SIT/UAT/cutover, and remain accountable through production hypercare. This role is critical due to our broad external and internal interface landscape, which spans retained operational systems, regulators, banks, payment services, e-invoicing/e-signature, communications, calendar systems, biometrics, content, and analytics services. You must have the capability to design and build, rather than simply coordinate developers. Key Responsibilities Architecture & Design: Own integration architecture execution, maintain the Interface Register, and produce comprehensive MD.070 designs covering source/target, patterns, mappings, security, error handling, retries, reconciliation, monitoring, and ownership. Hands-On Development: Build and configure approved OIC integrations and OCI API Gateway exposures using REST, SOAP, file/batch, and event-driven patterns. System Integration: Integrate Oracle Fusion with retained operational systems and approved external services (regulatory/authority platforms, banking/payment services, e-invoicing, e-signature, SMS, calendars, biometric devices, content services, and analytics feeds). Security & Compliance: Implement interface identities, OAuth/OIDC, mTLS where required, certificates/secrets, scoped accounts, least privilege, and payload masking. Error Handling & Quality: Implement transformations, validations, business identifiers, error taxonomy, retry/replay mechanisms, and duplicate-prevention/idempotency controls. Testing & Deployment Support: Own integration unit testing and support SIT, E2E, UAT, defect resolution, reconciliation, and production cutover sequencing. Operations & Hypercare: Provide operational monitoring for failures, backlogs, retries, and latency; maintain recovery runbooks and support production hypercare. Workload Management: Assess workload and interface volumes, escalating early if a second OIC developer is required. Requirements Requirements (Must-Have Criteria) Experience: 10+ years of Oracle Integration Cloud / Oracle Integration experience with current, proven hands-on development capability. Technical Skills: Strong REST, SOAP, file/batch, and event-driven integration design and build experience. Hands-on Fusion adapters and supported Oracle Fusion integration patterns. API design and exposure experience using OCI API Gateway where appropriate. Strong data transformation, mapping skills, orchestration, lookups, routing, and reusable connection patterns. Security & Reliability: Deep practical knowledge of interface security (OAuth/OIDC, mTLS, secrets management, payload masking) and robust fault…
