Responsibilities:

Explore complex, multidimensional search data at large e-commerce scale, challenge assumptions, and generate new hypotheses and opportunities for search, recommendations, ranking, and personalization
Conduct query-level analysis: zero-results, query reformulation/refinement, abandonment, head/tail behavior, and segmentation by query, category, and intent
Conduct ranking analysis: position bias, CTR by position, and relevance vs. business metric trade-offs
Define, track, and interpret search KPIs: CTR, PDP view rate, add-to-cart (A2C), conversion, revenue, and zero-results rate
Design and evaluate online experiments for ML/search — ranking, personalization, recommendations, facets, and hybrid/vector search — with rigorous statistical evaluation
Build end-to-end metrics layers: from raw event/tracking data through product-level datasets to clear visualizations
Work hands-on with event-level and server-side search logs
Collaborate closely with Product Owners, Data Scientists, MLOps, and ML/Search Engineers to build and improve analytical, statistical, and ML solutions that drive product and business KPIs
Lead cross-functional analytical work at a senior level

Qualifications
Must have:

Strong SQL and Python (Pandas) skills, backed by solid statistics — with the ability to produce clear visualizations (emphasis on SQL/Python/statistics rather than dashboarding tools)
Familiarity with search funnel analytics and terminology: query, search results, PDP, add-to-cart (A2C), purchase
Hands-on experience with query-level and ranking analysis (zero-results, reformulation, abandonment, position bias, CTR by position, relevance vs. business trade-offs)
Experience defining, tracking, and interpreting search KPIs (CTR, PDP view rate, A2C, conversion, revenue, zero-results rate)
Experience with online experimentation for ML/search, including statistical evaluation of ranking, personalization, and recommendation experiments
Proficiency working with event-level and server-side search logs
Proven record of cross-functional collaboration with Product Owners, Data Scientists, MLOps, and ML/Search Engineers, delivering solutions that impact product/business KPIs; ability to lead cross-functional work at a senior level
Experience building complex, multidimensional metrics layers and delivering end-to-end analytical/statistical/ML solutions; comfort with search data at large e-commerce scale
Proactive mindset: ability to dive into complex problems, explore data, and challenge assumptions
Genuine enthusiasm for search, recommendations, ranking, personalization, and AI-powered product discovery; curiosity about how customers search, browse, and compare
