Senior Frontend Engineer

THE ROLE AND THE TEAM

The ZEOS B2B Platform is the core engine enabling our partners to seamlessly integrate and scale within the Zalando ecosystem. As a Senior Frontend Engineer, you will be a key contributor to our partner-facing ecosystem, working either on our central Portal, specialized Portal Applications, or within the Platform Integration team. We provide a holistic, API-first environment that empowers partners to manage their business with speed and flexibility.

In this role, you will help shape the future of our web architecture, moving beyond simple interfaces to build complex, modular systems. You will work in an agile, cross-functional team of engineers and product managers to create high-performance applications that serve as the primary interface between ZEOS and the global market. At ZEOS, seniority means more than just writing code; it means taking ownership of the entire lifecycle, mentoring peers, and ensuring our frontend landscape is scalable, secure, and user-centric.
