We are actively seeking an Principal SAP Integration Architect. This is a remote role based in Brazil.

Position Summary

The Principal SAP Integration Architect owns the integration layer between Rimini Street's Agentic ERP Platform and SAP enterprise systems. The primary focus is SAP ECC and Enhancement Packages (EHP 5–8), which represent the core of Rimini Street's SAP client base. This role designs and builds the connectors, data mappings, and transaction flows that enable AI agents to read from and write to SAP environments safely and reliably.

Reporting to the VP, Platform Engineering, this lead combines deep SAP ECC domain knowledge with modern integration engineering skills. The ideal candidate understands SAP system architectures, BAPIs, RFCs, IDocs, and data models at a level that allows them to design agent-safe integration patterns—defining which SAP operations become AI-consumable tools, handling transaction boundaries, and enforcing safe-write patterns across complex business processes.

Essential Duties & Responsibilities

SAP Integration Architecture

• Design and own the integration architecture between the Agentic ERP Platform and SAP ECC/EHP environments.

• Define the tool taxonomy for SAP: determine which BAPIs, RFCs, and transactions become agent-consumable tools, and in what shape.

• Design transaction boundary management: SAP LUW handling, commit/rollback strategies, concurrency controls, and data consistency guarantees for agent-initiated operations.

• Enforce the Park/Post pattern: every SAP write tool ships in safe (park/draft) and full (post/submit) variants, ensuring agents can stage changes for human review before committing.

• Implement the tiered autonomy progression for SAP tools: Read → Draft → Supervised → Autonomous, controlling which operations agents can execute at each trust level.

Connector Development

• Build and maintain SAP system connectors that translate platform requests into BAPI/RFC calls, IDoc exchanges, or OData API interactions.

• Implement data validation and transformation logic specific to SAP data models, structures, and business rules.

• Design fallback mechanisms for integration path failures, including degraded-mode read-only access and queued write operations.

• Build connection management for SAP environments: SAP JCo connection pooling, credential handling, and multi-system landscape support.

Domain Expertise & Guidance

• Serve as the SAP ECC subject matter expert for the engineering team, advising on SAP-specific constraints, capabilities, and best practices.

• Guide MCP Server Developers on SAP-specific tool implementations, schema design, and smart response patterns.

• Design test strategies for SAP integration: sandbox environments, data fixtures, and regression suites.

• Document SAP integration patterns, known limitations, and troubleshooting guides for the engineering team.

Cross-functional Collaboration

• Collaborate with the Integration Lead (Oracle) to ensure consistent integration patterns and shared tooling across ERP platforms.

• Work with AI Data Engineers on SAP data extraction for knowledge pipelines and retrieval systems.

• Coordinate with QA Engineers on integration test coverage and validation strategies.

• Provide input to the Security & Identity Lead on SAP-specific authentication and authorization requirements (SAP roles, authorisation objects).

Experience

• 12+ years of experience working with SAP systems, with deep knowledge of SAP ECC and Enhancement Packages.

• 8+ years of integration engineering experience: building APIs, connectors, or middleware for enterprise systems.

• Hands-on experience with SAP integration interfaces: BAPIs, RFCs, IDocs, OData, and CDS views.

• Experience designing integration architectures for complex, multi-module SAP implementations.

• Awareness of S/4HANA is valued; ECC depth is primary.

• Background in enterprise software support, SAP consulting, or B2B platforms preferred.

Technical Skills

Required

• SAP ECC and EHP: BAPIs, RFCs, IDocs, OData services, and CDS views.

• ABAP fundamentals: ability to read, debug, and where necessary extend ABAP code for integration purposes.

• SAP JCo (Java Connector) for RFC/BAPI connectivity.

• Java 21 with Quarkus 3.x for connector and tool server development.

• RESTful API design and implementation.

• PostgreSQL for platform-side data operations.

• OpenTelemetry for distributed tracing across agent-to-tool-to-SAP integration boundaries.

• Transaction management: SAP LUW, commit/rollback strategies, idempotency, and concurrency handling.

• Git version control and CI/CD practices.

• Testing: integration test design, mock services, and contract testing.

Preferred

• Experience with SAP Cloud Platform Integration (CPI) or SAP Integration Suite.

• Knowledge of SAP Gateway and OData service development.

• Familiarity with the Model Context Protocol (MCP) or agent-tool interface patterns.

• Understanding of durable execution patterns (Restate or equivalent) for long-running integration workflows.

• Experience with SAP BTP (Business Technology Platform) and SAP HANA.

• SAP authorisation concepts: roles, profiles, and authorisation objects for secure integration design.

• S/4HANA awareness: API differences, compatibility layer, and migration considerations.

Skills & Competencies

• Deep SAP ECC domain knowledge; understands ERP business processes, not just technical interfaces.

• Integration mindset; designs for reliability, observability, and graceful failure handling.

• Collaborative; works effectively with platform engineers, agent developers, and Oracle integration counterparts.

• Clear communicator; can translate SAP-specific constraints into actionable guidance for the broader team.

• Problem solver; experienced in diagnosing complex integration issues across system boundaries.

• Self-motivated and effective in a remote environment.

• Fluent in English (written and verbal).

Desired Qualifications

• Bachelor's or Master's degree in Computer Science, Information Systems, or related field.

• SAP certifications (SAP Technology Consultant, ECC, or Integration).

• Experience in enterprise software support or SAP consulting.

• Background in Rimini Street's supported SAP product lines is a strong advantage.

Location & Travel

Location: Remote, Brazil

Travel: Minimal; occasional travel for team meetings or training

Language

Fluent English required (written and verbal); Portuguese is a plus
