Principal Software Engineer CuCa Tech (All Genders)

THE ROLE & THE TEAM

As a Principal Software Engineer in Zalando’s Customer Care (CuCa) Tech department, you will be the primary architect of our transformation from traditional service models to AI-powered automated resolution. You will move beyond a single team's scope to provide hands-on technical leadership for the entire department.

Your mission is to define the architecture for systems where complex AI models meet customer-facing production environments. You will ensure that automated intelligence handles high-volume customer queries monthly while maintaining a seamless "human-in-the-loop" fallback for complex cases. You will be the go-to expert for Product and Engineering Management, ensuring our technology roadmap directly supports the next generation of automated customer care.
