The Role: We are looking for a Senior SAP S/4HANA Developer on behalf of our client to lead backend and full-stack development within a modern S/4HANA enterprise landscape. In this role, you will take technical ownership of designing, building, and extending mission-critical SAP applications—leveraging modern development paradigms such as the ABAP RESTful Application Programming Model (RAP) and Core Data Services (CDS). You will drive modern, upgrade-stable SAP development by adhering strictly to "Clean Core" architectural guidelines. Rather than relying on legacy, modification-heavy ABAP patterns, you will build side-by-side extensions on SAP BTP, expose optimized OData services, push heavy calculations down to the in-memory SAP HANA database, and deliver intuitive user experiences via SAP Fiori. What we’re looking for: 5+ years of SAP development experience, with at least 3 years dedicated to S/4HANA, featuring expert command of Object-Oriented ABAP (OO-ABAP), New ABAP Syntax (7.4+), and RAP (ABAP RESTful Application Programming Model). Advanced proficiency authoring complex Core Data Services (CDS) Views, parameters, associations, access controls (DCL), and ABAP Managed Database Procedures (AMDP) for code push-down performance. Extensive experience creating and exposing OData v2/v4 services via SAP Gateway (SEGW) or RAP business services for UI consumption and third-party cloud integrations. Practical experience developing custom SAP Fiori / SAPUI5 applications or configuring Fiori Elements apps using CDS annotations. Firm understanding of modern SAP extensibility frameworks, including On-Stack Developer Extensibility (Embedded ABAP / Steampunk) and Side-by-Side Extensibility using SAP Business Technology Platform (BTP). Proven ability to trace, profile, and optimize ABAP/HANA execution using Runtime Analysis (SAT), ABAP Test Cockpit (ATC), SQL Trace (ST05), and SQL Monitor (SQLM). Nice-to-have skills: Hands-on experience developing side-by-side extensions on SAP BTP using Node.js/CAP (Cloud Application Programming Model) or ABAP Cloud. Background in legacy-to-S/4HANA code remediation, custom code analysis (CCA), and migration projects. Exposure to Event-Driven Architecture using SAP Event Mesh or Kafka integrations. Knowledge of standard SAP S/4HANA business process modules (FI/CO, SD, MM, or PP). Responsibilities: Architect, build, and maintain high-performing transactional and analytical SAP applications using ABAP RAP, CDS views, and AMDP. Build upgrade-stable enhancements and side-by-side extensions, strictly minimizing legacy modifications to protect core system stability. Design and expose secure OData endpoints to power SAP Fiori user interfaces, mobile apps, and enterprise cloud integrations. Perform automated code checks (ATC), enforce clean code standards, conduct peer code reviews, and optimize legacy custom code for S/4HANA compatibility. Collaborate closely with SAP functional consultants, enterprise architects, and BTP specialists to translate business requirements into technical solution specifications.
