Staff / Principal Applied AI Researcher (Agentic Search)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff / Principal Applied AI Researcher (Agentic Search) based in Switzerland. This is a senior applied research opportunity focused on redefining how AI systems access, retrieve, and reason over information from the web. You will help build an agent-native search platform designed for machines rather than traditional human search experiences. The role combines cutting-edge research with hands-on system design and a strong expectation of delivering measurable impact in production. You will work on retrieval, ranking, query understanding, LLM grounding, and evaluation for complex multi-step agent workflows. Your work will operate under demanding requirements for relevance, reliability, latency, and cost at significant scale. With substantial ownership over research direction and technical architecture, you will help shape foundational capabilities for the next generation of AI systems.
