The ideal candidate will combine strong hands-on experience with the SAP Cloud Application Programming Model (CAP), SAP Fiori/UI5, BTP services, and CI/CD tooling with a clear understanding of clean-core principles, multi-tenant SaaS design, and SAP integration best practices. Maintain comprehensive, current technical documentation — including architecture diagrams, design decisions, configuration references, runbooks, and operational procedures — so that the system remains supportable, auditable, and easy to onboard new engineers onto over time.
