• Design and build API-based integrations connecting SAP S/4HANA with cloud-based platforms such as OneSource and SAP Ariba, using REST/SOAP web services, OData, and middleware tools
• Manage authentication, error handling, and monitoring for cloud-to-cloud and cloud-to-on-premise integration flows (e.g., OAuth, API keys, certificates)
• Partner with OneSource and Ariba technical teams to troubleshoot API-level integration issues, including payload errors, timeouts, and data mapping mismatches
• Troubleshoot and resolve technical integration defects, including interface failures and data mapping issues

Technical Design & Architecture Support

• Collaborate with functional tax systems analysts and architects to translate requirements into technical designs

Testing & Deployment

• Support transport management and deployment of technical changes across landscapes
• Maintain technical documentation for developed interfaces and programs

Communication & Collaboration

• Collaborate with onshore resources and cross-functional teams to prioritize and deliver technical work

Qualifications & Experiences:

• 7+ years of hands-on SAP ABAP development experience
• Demonstrated integration development experience (interfaces, enhancements, BAdIs, RFC/API-based integrations, etc.)
• Must have experience integrating SAP S/4HANA with external tax engines such as OneSource, Vertex, or similar
• Hands-on experience building and supporting API-based integrations (REST/SOAP, OData) between SAP and cloud-based platforms
• Experience troubleshooting integration issues across a hybrid landscape spanning on-premise SAP and cloud-based SaaS platforms (e.g., OneSource, Ariba)
• Strong analytical and problem-solving skills
• Excellent written and verbal communication skills
• Bachelor's degree in computer science or a related field, or equivalent experience

Not Required but preferred experience:

• Functional tax knowledge - understanding of tax postings and requirements
