SAP Business One Integration Engineer

About the role

You will own the SAP Business One connector end‑to‑end, from designing a generic connector SDK to implementing the Service Layer connector. Immediate access to a real SAP B1 test company allows you to start development without waiting for external sandbox access.

• Design and build a generic connector interface (Connector SDK) with contract‑test kit and mock implementation.
• Develop the SAP Business One connector via the Service Layer (OData v3) for read and scoped write operations.
• Implement OAuth 2.0/service‑account authentication and ensure idempotent, retry‑safe request handling.
• Work directly with Voyage’s SAP B1 test company database throughout development.
• Plan an upgrade path to OData v4 as the company moves to a newer SAP B1 version.

Required profile

• Hands‑on experience integrating with SAP Business One, specifically OData v3/v4, Service Layer, and HANA.
• Proven experience with OAuth 2.0/service‑account authentication patterns.
• Experience designing idempotent, retry‑safe API integrations.
