SAP Business One Integration Engineer

You will take full ownership of the SAP Business One connector, managing it end-to-end. This includes developing a generic connector interface that will serve as the foundation for all future integrations, as well as building and maintaining the SAP Business One Service Layer connector itself. From day one, you will have direct administrative access to a live SAP Business One test company environment, enabling you to begin hands-on development immediately without waiting for external sandbox access.

Key Responsibilities

- Design and develop a generic connector interface (Connector SDK) that future system integrations will implement. This includes creating a contract-test kit and a mock implementation to support development and testing.
- Build and maintain the SAP Business One connector using the Service Layer (OData v3), compatible with the current SAP B1 version 9.3 instance. Your work will cover both read operations and narrowly scoped write operations.
- Implement OAuth 2.0 and service-account authentication mechanisms to ensure secure access.
- Develop idempotent and retry-safe request handling to improve reliability and fault tolerance.
- Work directly with Voyage’s SAP Business One test company database throughout the development lifecycle.
- Plan and prepare for an upgrade path to OData v4 as the organization transitions to a newer SAP Business One version.

Required Qualifications

- Proven hands-on experience integrating with SAP Business One, specifically with OData v3 and/or v4, the Service Layer, and HANA as the underlying database. General ERP integration experience alone will not suffice for this role.
- Strong knowledge of OAuth 2.0 and service-account authentication patterns.
- Demonstrated ability to design API integrations that are idempotent and retry-safe, ensuring robustness in communication.

Preferred Qualifications

- Experience developing SAP Business One add-ons or working with the DI API.
- Prior experience integrating SAP Business One with external platforms, beyond internal SAP customization projects.

This role offers a unique opportunity to work deeply with SAP Business One integration at a technical level, contributing to a foundational connector that will support future system expansions. You will be empowered to work directly with a live test environment from the outset, allowing for immediate impact and iterative development.
