• Build Advanced Relevance Features: Architect the features and models that power our core ranking and re-ranking systems, using insights derived from deep content and query analysis.
• Own the Science of Search Evaluation: Champion a culture of data-driven decision-making. You will design and analyze offline experiments and tests to prove the impact of our work and guide the product roadmap.
• Collaborate on Product Strategy: Act as a strategic partner to Product Managers and Engineers. Gather and analyse user feedback, identifying their information needs. Your analysis and insights will be critical in identifying new opportunities and shaping the future direction of our search and discovery products.

What We're Looking For

• A Master’s or PhD in a quantitative field (e.g., Computer Science, Physics, Mathematics) and 4+ years of professional experience in data science with a focus on Search or Recommender Systems.
• A proven track record of working on search relevance, ranking, query understanding or solving closely-related NLP problems.
• Demonstrable, hands-on experience building, fine-tuning, and evaluating a range of language models for specific tasks like classification, NER, and semantic similarity.
• Experience in experimental design and statistical analysis. Expertise in creating evaluation datasets and developing relevance guidelines. You know how to ask the right questions and how to design experiments that provide clear, statistically significant answers.
• A talent for structuring ambiguous problems and applying logical reasoning, translating complex challenges into clear, actionable plans.
• High proficiency in Python and data science libraries (e.g., Pandas, NumPy, Scikit-learn, PyTorch/TensorFlow, Hugging Face) and familiarity with SQL or other query languages.
• The ability to distill complex findings into clear, concise insights for diverse audiences, from engineers to executives. You are a collaborator by nature.

Bonus Points:

• Direct experience in the financial services or financial data industry.
• Experience with knowledge graph construction.
• Experience analyzing data from search platforms like Vespa.
