Senior SAP Architect

Senior SAP Architect

We are seeking an experienced Senior SAP Integration Architect to lead the design and implementation of robust, scalable, and secure integrations between SAP S/4HANA and a range of enterprise systems. In this role, you will drive integration strategies across OData, IDoc, BAPI, and SAP CPI/PI/PO, while ensuring that solutions are resilient, observable, and aligned with modern cloud-native practices such as event-driven messaging, OAuth-secured APIs, and fault-tolerant architecture.

This is a high-impact technical leadership role requiring hands-on delivery experience, solution ownership, and active collaboration with Java developers, DevOps, and SRE teams in a regulated, high-volume environment.

Mode : Hybrid (3 days/week in office)

Notice Period : Immediate to 21 days

Key Responsibilities :

- Lead integration design for high-volume SAP modules (orders, invoices, inventory) using OData, BAPI, IDoc, and SAP CPI/PI/PO.

- Develop and optimize CPI message flows with transformations, mappings, routing, and external system connectivity.

- Ensure integration resilience using strategies like retries, async messaging, dead-letter queues, and rollback handling.

- Collaborate with enterprise architects, Java backend teams, and DevOps to align SAP integration logic with modern application ecosystems.

- Handle secure API exposure using OAuth2, SAML, and integrate with SAP BTP API Management for access governance.

- Integrate SAP-side messaging with event-streaming platforms like Kafka or RabbitMQ.

- Support observability by aligning SAP logs and traces with tools like Dynatrace, Splunk, or Prometheus, and work with SRE teams to ensure system health and traceability.

- Contribute to system hardening discussions through HA/DR design awareness, integration testing, and failure recovery planning.

- Document integration patterns, troubleshoot issues, and participate in architecture and CAB reviews in a structured enterprise ITIL-based environment.

Technical Skills & Expertise :

Must-Have :

- SAP S/4HANA Integration (OData, BAPI, IDoc) : Experience designing, deploying, and troubleshooting OData services and IDoc/BAPI flows; able to enhance CDS views for external consumption.

- SAP CPI (Cloud Platform Integration) : Hands-on experience with CPI flows, including mapping, transformation, routing, and adapter configuration.

- SAP PI/PO : Strong understanding of orchestration, ESR, and integration via adapters, with hands-on mapping (Graphical, XSLT, Java UDFs).

- Resilient Integration Design : Able to implement and tune retry logic, backoff, dead-letter handling, and exception strategies for transactional integrity.

- Secure API Exposure : Worked with OAuth2/SAML-secured APIs and participated in SAP BTP API Management for token validation and policy controls.

- Kafka/RabbitMQ Integration : Experience connecting SAP services to Kafka or RabbitMQ through CPI or custom connectors.

- Observability & Logging : Integrated SAP with observability platforms like Splunk, Dynatrace, or Prometheus for log tracing and failure diagnosis.

- High Availability (HA/DR) Design : Understands HA/DR considerations in SAP HANA environments and reflects them in integration architecture.

- Cross-Functional Collaboration : Experience working alongside Java, DevOps, and SRE teams to ensure robust, well-monitored integrations.

Nice-to-Have :

- SAP Event Mesh / Enterprise Messaging : Familiar with async decoupling using Event Mesh or Kafka-based patterns.

- Advanced BTP API Management : Exposure to JWT assertions, token propagation, and policy design for advanced API governance.

- CI/CD for SAP Artifacts : Awareness of CPI transport automation using Git, Jenkins, or SAP-native CI/CD tools.

- Cloud Messaging (Azure Event Grid / GCP PubSub) : Understanding of cloud-native alternatives for event streaming.

- ABAP Debugging (OData/CDS) : Ability to trace backend logic behind OData services using ABAP.

- Grafana/Prometheus Integration : Exposure to custom metric publishing or SAP observability via Grafana dashboards.

- ITIL / CAB / ServiceNow : Familiar with enterprise production support and change control frameworks.
