Senior SAP FICO

SAP FI Developer

Irving TX (Hybrid)

Role Summary

The SAP FI Developer designs, builds, and supports custom development objects within SAP Finance (GL, AR, AP) across SAP ECC and SAP S/4HANA landscapes, with strong emphasis on S/4HANA-native development. This role delivers enhancements, integrations, and reports that support Finance transformation and automation initiatives — working closely with functional consultants, architects, and project managers to translate finance requirements into robust, performant technical solutions.

The developer is expected to have deep hands-on experience with core FI development objects, SAP's modern extensibility toolkit (RAP, CDS Views, Fiori/UI5), and integration technologies connecting SAP Finance to third-party platforms such as payment processors, banking systems, and AR/AP automation tools.

Job Responsibilities

• Design, develop, and unit-test custom objects supporting GL, AR, and AP processes across SAP ECC and S/4HANA.
• Build and enhance FI-relevant custom developments, including enhancements to SAP standard programs, BAdIs, user exits, and validation/substitution logic.
• Develop CDS Views, OData services, and RAP-based applications to support Fiori apps and S/4HANA reporting.
• Build and maintain interfaces between SAP FI and third-party systems (banks, payment processors, AR/AP automation platforms) using IDocs, BAPIs, APIs, and SAP PI/PO or Integration Suite.
• Support development of custom Fiori/UI5 apps and workflow-based approval processes tied to Finance transactions.
• Partner with functional consultants to translate FI/FSCM business requirements into technical designs, estimates, and specifications.
• Develop and support automation solutions using SAP BTP, RPA connectors, or AI/ML services integrated with SAP Finance processes.
• Perform code reviews, performance tuning, and troubleshooting for existing custom FI objects, ensuring alignment with SAP clean core principles where applicable.
• Support testing (unit, integration, UAT), migration/cutover activities, and post-go-live hyper care for FI development objects.
• Maintain technical documentation for custom developments, interfaces, and enhancements.

Technical Skills Required

• Strong hands-on ABAP development experience, including OOP ABAP, with solid grounding in FI-relevant objects (GL, AR, AP tables, BAPIs, BAdIs, user exits, validations/substitutions).
• Proven S/4HANA development background — CDS Views, AMDP, RAP (RESTful ABAP Programming Model), and Fiori Elements/UI5 app development.
• Experience building and maintaining SAP integrations — IDocs, BAPIs, RFCs, REST/SOAP APIs, and middleware such as SAP PI/PO or SAP Integration Suite.
• Familiarity with SAP BTP and extensibility concepts (side-by-side vs. in-app extensibility, clean core principles).
• Experience developing interfaces to third-party financial platforms — banks, payment gateways/processors, or AR/AP automation tools (e.g., High Radius or comparable) — including API-based integration patterns.
• Working knowledge of FSCM modules (Cash, Credit, Collections, Disputes) sufficient to support development in these areas.
• Experience with SAP Workflow, Business Rules Framework plus (BRF plus), or comparable tools for approval/automation logic.
• Understanding of performance optimization, debugging, and troubleshooting techniques for custom FI developments in S/4HANA.
• Exposure to DevOps/CI-CD practices for SAP development (e.g., SAP Transport Management, ADT/Eclipse-based development) a plus.
