Responsibilities

• We are seeking an SAP Fiori Back-End Developer to create, enhance, and resolve issues within the OData services and APIs that power our Fiori applications within our SAP S/4HANA environment.
• Your primary focus will be writing modern ABAP code, working within the ABAP RAP framework, and configuring the content of the Fiori Launchpad.
• While custom front-end Fiori (UI5) development is not required, this role thrives on a working knowledge of standard SAP UI extensibility tools to adapt existing applications.
• Build new OData V2 and V4 services using the ABAP RESTful Application Programming Model (RAP).
• Efficiently resolve, fix, and optimize existing services in S/4HANA.
• Develop reliable back-end logic using the Object-Oriented (OO) ABAP programming model (Classes, Interfaces) within ABAP Development Tools (ADT / Eclipse).
• Integrate and support existing BAPIs, RFCs (Remote Function Calls), and Function Modules, particularly when incorporating them into Unmanaged RAP scenarios.
• Maintain and enhance older OData services built with the classic SAP Gateway (SEGW).
• Build or modify back-end Core Data Services (CDS) views.
• Metadata Extensions (MDE) to control data exposure and UI behavior.
• Utilize Key User Extensibility tools (e.g., Custom Fields and Logic) and Fiori UI Adaptation mode to modify standard SAP Fiori apps without writing custom front-end code.
• Manage Technical Catalogs, Business Catalogs, Spaces, Pages, Target Mappings, and Fiori Tiles.
• Use tools like Postman and SAP Gateway Client to test APIs.
• Write ABAP Unit tests and optimize database performance (e.g., using AMDP for SAP HANA).
• Partner with business analysts to define data requirements and work seamlessly with front-end developers to ensure smooth API integration. _ Are you a MATCH?

Requirements

• Ideally, you bring 3 to 6 years of solid, hands-on experience in standard SAP ABAP development (including OO ABAP, RFCs, and Function Modules), with recent experience on an SAP S/4HANA system.
• Practical experience building and troubleshooting OData services using ABAP RAP (both Managed and Unmanaged scenarios).
• Demonstrated capability to work with and enhance classic SEGW-based OData services.
• Skilled in using Eclipse / ADT for development tasks.
• Practical experience using Key User Extensibility (CFL) and Fiori UI Adaptation mode.
• Effective and empathetic communication skills with the ability to explain back-end constraints to non-technical stakeholders.
• A proactive and team-oriented approach capable of thoughtfully designing logic and delivering services.

Preferred

• Knowledge of Fiori front-end technologies (SAP UI5, Fiori Elements, JSON) to better understand how the UI consumes back-end APIs.
• Familiarity with SAP Business Technology Platform (BTP) ABAP Environment.
• Familiarity with modern ABAP version control (e.g., Git / gCTS).
