Job 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 (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.
