Senior Backend Engineer; Java​/Kotlin, Streaming Europe

Join the team at one of the world’s leading meal-kit delivery companies and help build and operate a production-grade real-time streaming platform that powers data-driven decisions across the organization. New team is being formed to unify forecasting workflows across multiple markets by building a platform around forecasting models developed by data science teams. This platform will integrate forecasting outputs with upstream and downstream systems such as production, procurement, and inventory-related services, enabling more consistent and scalable operational processes.

In parallel, the team is responsible for maintaining and evolving an existing real-time streaming application that manages menu availability and sold-out logic. This system integrates with inventory and other operational services through event-driven architecture and stream processing. The focus of the team is to ensure reliability, extend functionality, and support the continuous evolution of this operational platform in collaboration with data, backend, and platform engineering teams.
