Java Developer

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.
