Job Details
Job Title: Developer Premium III - SAP ECC / S/4HANA RAP Technical Developer
Location: Washington, DC (100% Onsite from Day 1)
Duration: 6 Months with long term extension
Job Details: We are seeking an experienced SAP ECC / S/4HANA RAP Technical Developer (Level 3) for an onsite engagement (no remote work). This role is part of our finance ERP program and requires a senior developer who can deliver robust, upgrade-safe solutions aligned with SAP architecture and modern ABAP practices.
Background: Client is undergoing a multi-year, multi-stage transformation from SAP ECC on-premise to SAP S/4HANA on-premise. The program involves a large volume of custom ABAP code built to support specialized business processes.
- In Stage 1, this code must be adapted for compatibility with S/4HANA s simplified data structures and programming model.
- In Stage 2, it will be re-engineered using clean-core principles and cloud-ready ABAP (strict ABAP) within S/4HANA leveraging frameworks such as RAP, CDS, and AMDP.
- In Stage 3, selected components may shift to SAP BTP using side-by-side extensibility where it provides architectural or scalability benefits.
- This is a techno-functional role that requires strong hands-on development capabilities combined with deep process understanding. The selected candidate will be expected to interpret functional requirements, participate in fit-gap assessments, and independently deliver scalable, upgrade-safe solutions that align with SAP s architectural direction.
- The role demands end-to-end accountability from technical design and performance optimization to security adaptation and clean extensibility.
- Candidates must be confident problem-solvers, effective collaborators across business and IT teams, and able to demonstrate their capabilities through a hands-on coding assessment during the evaluation process.
Minimum Requirements:
Candidates must meet all the below criteria.
- 15 years of SAP ABAP development in ECC
- 7 years of S/4HANA development experience
Core technical requirements:
- ABAP (on ECC & S/4HANA) with RAP (ABAP RESTful Application Programming Model) experience for designing and building upgrade-safe services and UIs.
- Proficiency with CDS views, OData, and performance-optimized data models.
- Familiarity with Fiori/UI5 development and integration patterns; experience on BTP is a plus.
- Ability to interpret functional requirements, perform fit gap, and take end-to-end ownership from technical design through delivery.
