What you'll do

• Take over the add-on after handover from the implementation partner and grow into full technical ownership
• Maintain and extend the add-on's freestyle Fiori app (SAPUI5) — filter panels, multi-select tables, Flexible Column Layout, object pages and platform embedding
• Extend the underlying ABAP RAP services (CDS entities, behavior definitions/implementations) and the OData V4 services the app consumes
• Work across the S/4HANA backend: custom tables, batch/material status logic and the status-transition rules that govern it
• Support the BTP integration flows that exchange batch and material data with our platform via the AWS middleware
• Set up and deploy the add-on in customer systems, working alongside each customer's SAP team
• Provide technical support to customers — troubleshooting, debugging, resolving integration issues
• Implement customer-specific configurations and adaptations
• Track work in Jira and document solutions and technical decisions in Confluence
• Collaborate with the platform backend team on API contract changes and improvements

Requirements

What we're looking for

• 1+ years working with SAP development
• Hands-on SAPUI5 / freestyle Fiori development (JavaScript, XML views, OData V4 consumption) — comfortable extending an existing app, not only generating one from a template
• ABAP knowledge, with willingness to deepen RAP (CDS views, behavior definitions) and integration patterns
• Familiarity with S/4HANA architecture
• Customer-oriented mindset for technical support and on-site collaboration
• Good problem-solving skills and attention to detail
• Clear communication with both technical and non-technical stakeholders
• Fluent English

Nice to have

• Experience with MM, SD or QM modules
• Exposure to SAP BTP and integration/eventing
• Experience with add-on delivery / transport management (e.g. SAP Add-on Assembly Kit)
• Experience with Java/Spring Boot (our platform side)
• German B1 or higher
•
