Delivery Hero is hiring a Senior Data Scientist for the Search Ranking team within its Global Search tribe in Berlin. Search at Delivery Hero spans more than 60 countries and 35 languages and handles over 80 million queries a day, so the ranking models built in this role directly shape what millions of customers see in the app. You will own the ranking stack end-to-end, designing and productionising deep neural ranking models such as DCN-V2, MMoE and Two-Tower architectures at high throughput and low latency. The role also pushes agentic ML research, using LLM coding agents to run large-scale autonomous experiment pipelines over feature engineering and Learning-to-Rank architectures. In addition you will own production model health and monitoring, partner with backend engineers, data engineers and product managers, and mentor junior and mid-level data scientists.
