THE ROLE AND THE TEAM

The ZEOS B2B Platform is the high-performance engine that allows our partners to seamlessly integrate into the Zalando ecosystem. As a Senior Fullstack Engineer, you will be a key architect of the services that power our partner-facing products and internal operational tools. Our mission is to transform complex business requirements into a scalable, API-first platform that empowers partners to grow with speed and flexibility.

In this role, you will lead the development of mission-critical microservices, ensuring they are resilient, secure, and cost-efficient. You will work within an agile, cross-functional team of engineers and product managers where technical excellence is balanced with business impact. At ZEOS, seniority means taking a holistic view of our system landscape—mentoring your peers, driving technical alignment across teams, and ensuring that our "You Write It, You Run It" culture is lived every day.

WHAT WE’D LOVE YOU TO DO (AND LOVE DOING)

• Engineer Scalable Backend Systems: Design, develop, and evolve high-performance Microservices using Java and Spring Boot, ensuring they handle the complexities of a global B2B landscape.
• Design Intuitive APIs: Help us build RESTful services that prioritize clarity and ease of use, ensuring a seamless experience for every developer who interacts with our platform.
• Own the Full Lifecycle: Support the "You Write It, You Run It" philosophy. You will be responsible for the entire journey of your code—from initial design and Gradle-based builds to deployment and 24/7 operational health.
• Master Cloud Infrastructure: Leverage AWS and Kubernetes to build resilient, distributed systems that are compliant-by-design and operationally transparent.
• Drive Engineering Standards: Set the bar for code quality through rigorous testing, code reviews, and the use of modern tools like Jackson for efficient data processing.
• Collaborate Across the Stack: While your heart is in the backend, you enjoy collaborating with frontend teams and have an interest in Fullstack contexts to ensure end-to-end feature success.
