Senior SAP S/4HANA Lead Developer

Job description:

We are seeking a Senior Developer with deep SAP S/4HANA expertise to drive hands-on development and technical leadership of development streams. This role translates architectural designs into high-quality, performant solutions while guiding and mentoring a development team. A key differentiator is the candidate's ability to leverage AI-powered tools and emerging AI capabilities within the SAP ecosystem to accelerate delivery and drive intelligent automation.

YOUR TASKS AND RESPONSIBILITIES:

• Hands-on technical development of SAP S/4HANA solutions using ABAP (including RAP), CDS Views, and SAP Fiori/UI5, while providing technical leadership, code reviews, and coding standards to the development team.
• Champion and enforce SAP's Clean Core methodology — ensuring custom developments leverage released APIs, key user extensibility, and side-by-side extensions on BTP rather than core modifications, to safeguard upgradeability and reduce technical debt. Ideally, experience with Project Kernseife is already given.
• Translate solution designs into detailed technical specifications, development estimates, and implementation plans in close collaboration with Solution Architects and Business Process Owners.
• Actively leverage AI-powered development tools (e.g., SAP Joule, GitHub Copilot, Cline) and explore SAP Business AI services to accelerate development, improve code quality, and embed intelligent scenarios into solutions.
• Drive modern development practices including CI/CD, test-driven development, and DevOps principles within the SAP S/4HANA context.
• Stay current with SAP S/4HANA innovations and AI advancements in the SAP ecosystem and upskill the team on AI-assisted development workflows.
• Ensure solution quality through design reviews, testing, performance optimization, and provide Level 3 support for complex technical issues.

WHO YOU ARE:

• Minimum Bachelor's degree in Computer Science, Information Technology, or related field, or equivalent work experience.
• 7+ years of hands-on SAP development experience with strong focus on SAP S/4HANA.
• Expert-level ABAP skills (ABAP OO, CDS Views, AMDP, RAP, BAdIs) and proven experience with SAP Fiori/UI5 and OData services.
• Strong understanding of SAP's Clean Core principles, including tier-based extensibility (on-stack vs. side-by-side), released APIs, and upgrade-safe development patterns.
• Experience leading development teams (3–8 developers) in agile delivery environments with a track record of high-quality, on-time delivery.
• Demonstrated hands-on experience with AI-assisted development tools and awareness of SAP Business AI offerings (SAP AI Core, Joule, embedded AI scenarios in S/4HANA).
• Solid understanding of SAP S/4HANA architecture, data models, and integration patterns.
• Familiarity with SAP BTP extension scenarios and development lifecycle tools (gCTS, ATC, abapGit, Cloud ALM).
• Strong problem-solving and communication skills with a growth mindset and passion for continuous learning — particularly regarding emerging AI trends and their responsible application in enterprise software.
• Experience in one or more of the following domains is preferred: Finance, Supply Chain Management, Asset Management, Commercial (Order-to-Cash / Contract-to-Cash), or Analytics & Reporting.
• SAP certification in S/4HANA development is preferred.
