Description:
We are seeking an experienced SAP ABAP Developer with strong S/4HANA expertise to design, develop, and support custom enhancements, integrations, and reports within large enterprise SAP landscapes. This role spans the full development lifecycle, including requirements analysis, technical design, hands-on coding, unit testing, performance tuning, and post-go-live support in close collaboration with functional consultants and business stakeholders. The ideal candidate will combine deep ABAP expertise — including core ABAP, ABAP OO, CDS views, AMDPs, and OData — with a strong understanding of S/4HANA architecture, Fiori integration, and clean-core principles that minimize technical debt and ease future upgrades.
Key Responsibilities
- Design and develop custom ABAP programs, enhancements, BAPIs, BADIs, user exits, and interfaces within SAP S/4HANA environments, following clean-core and modification-free principles wherever possible
- Build performant CDS views, AMDPs, and HANA-optimized ABAP code that leverages code pushdown and takes full advantage of S/4HANA’s in-memory architecture
- Develop and consume OData services and RESTful APIs to support Fiori applications and integrations with non-SAP systems
- Implement SAP Gateway services, including service registration, modeling, and lifecycle management
- Design and develop classical and interactive ALV reports, smart forms, Adobe forms, and modern Fiori-aligned output channels
- Build and maintain integration interfaces using IDocs, RFC, BAPI, Web Services, and the SAP API Hub
- Perform technical analysis of business requirements in collaboration with functional consultants, and translate them into well-documented technical designs
- Conduct thorough unit testing, support functional and integration testing, and resolve defects raised during UAT and post-go-live hypercare
- Lead performance tuning of ABAP code, SQL queries, and database access patterns, including the use of SAT, ST05, and HANA-specific diagnostic tools
- Support S/4HANA upgrades, system conversions, and code remediation activities, including SCMON / UPL analysis and clean-core readiness assessments
- Implement security best practices in custom developments, including authority checks, secure data handling, and compliance with internal SAP governance
- Document technical specifications, code reviews, and operational procedures in line with enterprise SAP standards
- Mentor junior ABAP developers and act as a technical reference within the SAP team
