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.
