Nebius is hiring a Staff or Principal Applied AI Researcher in Zurich for an agent-native search platform — a web access layer designed for AI systems rather than people. The work covers agentic retrieval where LLMs iteratively plan, query and refine results, plus multi-stage architectures for query understanding, rewriting, reranking and iterative retrieval, and new evaluation metrics where correctness is not measured by clicks. The posting asks for 8+ years in applied AI, ML or software engineering, production-scale shipping experience, search or retrieval background, transformer and embedding knowledge, and Python plus Go or C++.
