THE ROLE AND THE TEAM

The ZEOS B2B Platform department is the core engine enabling our partners to seamlessly integrate with and scale within the Zalando ecosystem. By unifying complex business services under a high-performance platform umbrella, we provide a holistic API-first environment that empowers our partners to grow their business with speed and flexibility.

As a Principal Software Engineer at ZEOS, you will be a key architect of the common platform and ecosystem that powers both partner-facing and internal products. In this role, you don't just build services; you shape the technical landscape that allows diverse B2B solutions to interact, scale, and thrive. Together with an elite team of engineers and product managers, you will design the foundational REST services and microservices that serve as the interface between our complex internal operations and the external market. With ZEOS we shape the future of the Zalando logistics ecosystem - please read more HERE.

You will be the architectural guide for a platform that turns business complexity into scalable, cost-efficient, and secure software. By bridging the gap between high-level business requirements and robust Java-based engineering, you will drive the cross-unit alignment necessary to keep our platform compliant, extensible, and best-in-class. Your work ensures that ZEOS remains the premier choice for B2B partners looking to leverage the power of Zalando’s infrastructure.
