Requirement Details:

Job Title: - Oracle Integration Cloud (OIC) Engineer

Location: Travel to MN once in a month

Duration: 6+ Months

The Oracle Integration Cloud (OIC) Engineer is a handson engineering and operations role responsible for the stability, enhancement, and longterm sustainability of client's integration ecosystem as part of the ExCAL enterprise transformation program. This position provides daytoday engineering support for over 100+ integrations, ensures seamless operations during hypercare and beyond, delivers minor enhancements, and builds organizational capability by crosstraining existing support teams across OIC, Boomi, and Azure Integration Services.

Reporting to the Integration & Data Platforms Lead, this role contributes directly to client's global integration standards, operational excellence, and BusinessasUsual (BAU) readiness as ExCAL transitions from program mode to enterprise sustainability.

Key Responsibilities

1. Production Support for 100+ ExCAL Wave 1 Integrations

• Provide endtoend operational support for the full portfolio of 100+ OIC integrations including ERP (Fusion), HCM, CRM, procurement, field services, and legacy ERP connectors.
• Monitor OIC runtime health using OIC dashboards, Oracle Enterprise Manager, and custom observability tools.
• Perform daily operational checks, message tracking, pipeline behavior analysis, and verification of intersystem data flows.
• Troubleshoot and resolve integration failures, message orchestration issues, mapping errors, connectivity failures, SLA breaches, and dependency gaps across OIC, Oracle Fusion, Azure, and onpremises systems.
• Partner with the ExCAL Program PMO, ___ SI teams, platform owners, and business stakeholders to rapidly triage and resolve issues during hypercare and early stabilization.
• Ensure all incidents follow ITSM workflows for incident, problem, and change management.

2. Minor Enhancements & Continuous Improvement

• Design, develop, test, and deploy minor enhancements to OIC interfaces, mappings, connection configurations, errorhandling logic, and orchestration flows.
• Implement changes required due to schema updates, new business rules, source/target system adjustments, or operational needs.
• Improve mapping transformations, XSLT processing, reusable components, and integration pattern consistency.
• Maintain backward compatibility and enforce appropriate version controls, including management of integration revisions in OIC.
• Collaborate with QA and business SMEs to ensure enhancements are fully validated in lower environments prior to production deployment.

3. CrossTraining & Capability Building

• Develop and deliver structured crosstraining programs for the existing support organization covering:
  • Oracle Integration Cloud (OIC)
  • Boomi Integration (where applicable)
  • Azure Integration Services (APIM, Logic Apps, ADF triggers/pipelines, eventdriven patterns)
• Build documentation sets including:
  • Integration playbooks
  • Troubleshooting guides
  • Errorcode dictionaries
  • Monitoring standards
  • Reusable patterns for OIC/Boomi/Azure
• Shadow and mentor support team members to transfer daytoday responsibilities, enabling a scalable BAU operating model.
• Conduct handson workshops to improve team proficiency in mapping, orchestration flows, runtime monitoring, and deployment lifecycle.

4. Integration Lifecycle Management

• Manage interface configuration updates across environments (DEV, TEST, STAGE, PROD), following strict changecontrol procedures.
• Ensure integration deployments are consistent, traceable, and compliant with ExCAL governance standards and enterprise architecture patterns.
• Maintain and update integration assets, connection credentials, certificate rotations, and security configurations.
• Validate every deployment against expected dependencies such as Fusion lookup codes, ERP flexfields, UCM document structures, or thirdparty API schemas.

5. Operational Excellence & Monitoring

• Enhance observability by implementing structured error codes, alerts, notification routing, and dashboard improvements.
• Ensure all integrations meet required SLAs for throughput, performance, and error recovery.
• Participate in major incident triage, perform rootcause analysis (RCA), and document corrective actions.
• Partner with cybersecurity to ensure integrations comply with identity/security requirements (OAuth2, certificates, rolebased access).

6. Documentation & Knowledge Management

• Maintain all integration artifacts including:
  • Sourcetotarget mappings
  • Logical and physical interface diagrams
  • Configuration tables
  • Connection definitions
  • Runbooks and support SOPs
• Ensure documentation is complete, accurate, and aligned with enterprise architecture standards.

Required Qualifications

• 5+ years of handson experience with Oracle Integration Cloud (OIC), including orchestration, mappings (XSLT), REST/SOAP integrations, message queues, and integration adapters.
• Strong understanding of Oracle Fusion ERP/HCM and related integration patterns (FBDI, SOAP services, REST resources, BIP reports, UCM uploads).
• Experience providing production support for largescale integration portfolios (50+ integrations).
• Strong troubleshooting skills across crosssystem data flows, API request/response cycles, and asynchronous eventdriven patterns.
• Working knowledge of Azure Integration Services (Logic Apps, APIM, ADF) or Boomi is highly desirable.
• Familiarity with DevOps pipelines, CI/CD automation, and environment promotion strategies.
• Experience working in ITSMdriven operational environments.
• Excellent communication and documentation skills.

Preferred Skills

• Experience supporting global ERP transformation programs.
• Knowledge of Databricks and Azure Data Engineering patterns.
• Familiarity with integration observability tools (Splunk, Azure Monitor, OIC Insight).
• Experience with certificate/key rotation, OAuth 2.0 flows, and secure integration design.

Success Measures

• Stable operation of 100+ integrations with minimal postgolive disruption.
• Reduction in recurring incidents due to improved error handling and proactive monitoring.
• Demonstrated uplift in support team capability through crosstraining and documentation maturity.
• Timely delivery of minor enhancements without regression.
• Alignment with ExCAL integration governance and architectural standards.
