Job Summary
The SAP Middleware Support resource will be responsible for the design remediation support and optimization of integration objects across the SAP ECC to S/4HANA brownfield migration landscape. This role will ensure continuity stability and performance of all system interfaces throughout migration testing cutover and post-go-live stabilization. For this REQ we can only accept US CIT for DoD!!
The senior consultant with 10-15 years overall experience will work closely with Basis functional data and ABAP teams to support end-to-end integration scenarios and enable seamless interoperability between SAP and non-SAP systems.
- Support design build and validation of SAP integration objects leveraging:
- SAP PI/PO (Process Integration / Process Orchestration)
- APIs (REST SOAP) IDocs BAPIs
- Maintain and support interface mappings data transformations and integration logic across ECC and S/4HANA landscapes
- Support publish/subscribe and event-driven integration patterns using middleware tools
- Assist in defining and executing integration strategy and deployment approach for S/4HANA conversion
- Assess existing ECC interfaces for S/4HANA compatibility and simplification impacts
- Support remediation of obsolete or non-compliant integration objects
- Update technical specifications interface mappings and transformation logic for S/4HANA readiness
- Identify opportunities to optimize or replace legacy integrations with modern API-based approaches
- Support third-party system compatibility assessments and interface redesign where required
- Support interface testing across:
- System Integration Testing (SIT)
- User Acceptance Testing (UAT)
- Mock Conversions and Cutover cycles
- Troubleshoot and resolve integration defects across environments
- Validate end-to-end data integrity and system interactions
- Support cutover planning and sequencing for middleware objects
- Provide post-go-live support for integration defects and performance issues
- Monitor middleware performance message queues and interface failures
- Support stabilization and defect triage during hypercare phase
- Partner with:
- Functional teams to validate business process integration
- ABAP developers for custom interface remediation
- Data migration teams for data flow consistency
- Basis/infrastructure teams for environment and transport management
- Support alignment of integration design with overall S/4HANA architecture and data strategy
