OIC INTEGRATION LEAD / DEVELOPER

# OIC INTEGRATION LEAD / DEVELOPER > BlackStone eIT · India (Remote) · Full-time · Posted 2026-10-05 **Workplace:** remote ## Description 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 handling (retries, backoff, idempotency, exception management). - **Lifecycle Ownership:** Demonstrated experience taking interfaces through unit testing, SIT, UAT, production cutover (endpoint switches, security validation), and operational support. - **Documentation:** Proven ability to produce clear MD.070 integration designs, test evidence, and operational runbooks. Plus Points / Preferred Qualifications - Practical API Gateway experience for externally exposed APIs. - Real-world integration examples across Oracle Fusion ERP, HCM, SCM, or CX. - Strong production-operability evidence showing how support teams trace and recover transactions using correlation IDs and dashboards. - Experience contributing to structured technical design frameworks such as OUM-ABF (TE.040, etc.). - Prior go-live and hypercare ownership experience on complex enterprise transformations. Note: Candidates with architecture-only backgrounds, generic middleware experience lacking Oracle Fusion adapters, or no evidence of production support/cutover ownership will not be considered. ## Apply [Apply at BlackStone eIT](https://apply.workable.com/blackstone-eit-2/j/DBC279DAF1/apply) --- Powered by [Workable](https://www.workable.com)
