We're looking for a Java Developer (B2B/contract) to build the services and APIs connecting a fast-growing consumer-tech platform with its group SAP environment.

This is a hands-on backend role focused on real business flows: orders, inventory, device lifecycle, invoicing, payments, returns, and financial data.

You'll own integrations from design to production - writing clean code, handling failure scenarios, and working directly with SAP, product, finance, operations, QA, and DevOps teams.

Your role with us:

• You'll design and maintain Java services that connect internal platforms with SAP ERP.
• You'll translate operational and financial processes into reliable, well-tested integrations.
• You'll take ownership of solution design, delivery, monitoring, and production support.

What you'll actually do:

👉 Build SAP integrations

• Develop Spring Boot services and APIs for data exchange between internal systems and SAP.
• Integrate through REST, OData, SOAP, IDoc, or RFC/BAPI interfaces, depending on the use case.
• Map and validate data for orders, inventory, returns, payments, invoices, and master data.
• Comfortable integrating internal systems with APIs from SAP (ECC or S/4HANA for example) processes across FI/CO, MM, and SD.

👉 Make integrations reliable

• Build authentication, idempotency, retries, queues, logging, and clear error handling.
• Write unit and integration tests and investigate issues across system boundaries.
• Monitor performance and data consistency in production.

👉 Keep delivery structured and moving

• Collaborate with SAP, product, finance, QA, and other tech teams.
• Estimate work clearly, document interfaces, and communicate dependencies early.
• Participate in code reviews and technical decisions.

What we're looking for:

• 3-5+ years of experience in Java development.
• Strong hands-on experience with Spring / Spring Boot and production APIs.
• System-integration experience with data mapping and failure recovery.
• Experience with REST APIs, messaging, and relational databases.
• Comfortable with Git, CI/CD, Docker, and production monitoring.
• Experience writing unit and integration tests (JUnit, Mockito).
• Good English and confidence working with technical and business stakeholders.

Nice to have:

• Experience integrating Java applications with SAP ECC or S/4HANA.
• Knowledge of SAP FI/CO, MM, or SD business processes.
• Hands-on exposure to SAP Integration Suite.
• Experience with RabbitMQ, Kafka, Kubernetes, or cloud environments.

Additional notes:

🚀🚀🚀 Quick hiring process → feedback within 48 hours.

→ Hybrid setup - occasional office days may be required.

• This is a 6-month rolling contract engagement with a growing product and integration roadmap.
• Flexible with notice periods of up to 4 weeks.
