Role Title: SAP CPI / BTP Integration Developer

Location: Remote

Primary Skills: SAP CPI, SAP BTP Integration Suite, API-led integrations, S/4HANA interfaces

Role Overview

The SAP CPI / BTP Integration Developer is responsible for designing, developing, and maintaining integration interfaces between SAP S/4HANA and external or internal systems using SAP Integration Suite (CPI) and SAP BTP services. The developer ensures secure, scalable, and upgrade-safe integrations following clean-core principles, API-first architecture, and modern event-driven patterns. The role collaborates closely with functional consulting teams, ABAP/RAP developers, security, infrastructure, and business stakeholders to ensure seamless, efficient, and compliant data flows across systems.

Key Responsibilities

Interface Design & Development

Build integration flows using SAP CPI / SAP Integration Suite, including synchronous, asynchronous, real-time, and batch data movement.

Develop and support SOAP, REST, OData, IDoc, RFC, and API-based integrations between SAP S/4HANA, SAP ECC, SAP MDG, external SaaS platforms, data lakes, legacy systems, and partner environments.

Design API-first contracts and ensure consistency in version control, security tokens, throttling, and lifecycle governance.

Integration Architecture & Patterns

Implement and support clean-core, side-by-side integration architecture aligned with SAP BTP patterns.

Develop integration logic using:

Event-driven messaging (Event Mesh, webhooks)

File-based interfaces

Mapping, transformation, enrichment, exception handling, and logging

Support modernization of legacy PI/PO or on-prem interfaces to CPI/BTP cloud-native patterns.

S/4HANA Integration Enablement

Collaborate with functional consultants and ABAP developers to expose OData services, CDS views, BAPI wrappers, and RAP-based APIs.

Integrate S/4HANA modules across master data, transactional data, and operational scenarios (OTC, PTP, RTR, manufacturing, logistics, asset maintenance, data governance, etc.).

Operational Support & Quality Assurance

Perform interface unit testing, system integration testing, regression testing, and automation where applicable.

Monitor interface performance, throughput, retries, and exceptions.

Troubleshoot CPI flows, failed messages, payload errors, mapping logic, timeouts, and connectivity.

Provide documentation, version control, deployment support, and production cutover execution.

Security, Compliance & Lifecycle Governance

Implement secure connectivity, OAuth, certificates, API security policies, and data governance.

Ensure compliance with enterprise integration standards, clean-core strategy, and upgrade-safe development.

Work with Enterprise Security, Basis, and Network teams for secure connectivity and firewall requirements.
