Job Description
We’re looking for a Data Scientist to help build and refine the evaluation system for a large-scale search engine. You’ll work closely with cross-functional teams to collect representative questions and datasets aligned with real-world use cases. Your responsibilities will include designing and executing statistical performance evaluations, analyzing results using visualization tools, and iterating on hypotheses to improve search quality. You’ll also be responsible for producing documentation similar to white papers—summarizing methodologies, findings, and insights to inform stakeholders and guide future development. This role requires a strong analytical mindset, hands-on coding ability, and the ability to move from exploratory notebooks to production-ready code. Collaboration with engineering and product teams is key, as is a passion for data-driven decision-making.
