Senior Staff Data Engineer- ML & AI Platform

At Marktplaats, data is at the heart of everything we do, but Intelligence is what differentiates us. We are building the ML/AI Platform that powers innovation across our entire Product & Technology landscape. You will join the Data Platform team—the engineering engine behind our Data & Analytics crew. You are stepping into a unique, hybrid ecosystem: we maintain a robust, high-scale traditional ML environment used daily by teams across Marktplaats, while simultaneously acting as the architects for our emerging GenAI capabilities. We are a team that values engineering rigor just as much as experimentation, looking for a leader to help us bridge the gap between stable production services and the bleeding edge of AI. As a Senior Staff Data Engineer – ML & AI Platform, you will be the bridge between infrastructure and Data Science, ensuring that our ML/AI environment is robust, scalable, and developer-friendly. Your mission is to solve the last mile problem of ML: making it easy to move models from a notebook to a high-scale production API. You are an R&D-minded leader who loves to experiment with the latest features (e.g., Databricks Agents, RAG Studio) and operationalize them into stable platform features. You will empower AI/ML Engineers and Data Scientists to be autonomous by building the tooling they need to self-serve.
