Senior Fullstack Engineer - ZEOS (all genders)

The ZEOS B2B Platform is the engine that lets Zalando's partners integrate into its ecosystem, and this Berlin-based Senior Fullstack Engineer role is a key architect position on the services behind partner-facing products and internal operational tools. The work is mainly backend: designing and evolving high-performance microservices in Java and Spring Boot, building clean versioned REST APIs, and running them on AWS and Kubernetes under a "You Write It, You Run It" model that includes 24/7 operational health. Seniority here means mentoring peers, driving technical alignment across teams and setting engineering standards through testing, code reviews and observability. The role also expects collaboration with frontend teams and a willingness to work across the stack. Zalando offers a hybrid model with up to 40% remote work per week.
