À propos
analyze diverse data sets including structured and unstructured. • Develop software programs, algorithms, dashboards, information tools, and queries to
clean, model, integrate and evaluate datasets. Keeps abreast of new analytic
methodologies and technologies. • Collaborate with functional business units to drive business solutions and direction.
Key Responsibilities include but not limited to: • Design, implement, and maintain enterprise-scale search solutions using Apache Solr • Develop and optimize semantic search capabilities using vector embeddings and neural
search models • Build custom indexers and indexing pipelines that support vector embeddings alongside
traditional text fields • Implement and tune Approximate Nearest Neighbor (ANN) algorithms for efficient
similarity search at scale • Design and optimize similarity functions (cosine, dot product, Euclidean) for various
search use cases • Build hybrid search systems that combine traditional keyword-based search with vector-
based semantic search • Perform traditional relevancy engineering including query analysis, field weighting,
boosting strategies, and result tuning • Conduct relevancy analysis using quantitative metrics and qualitative evaluation methods • Monitor search performance metrics and implement continuous improvements • Work cross-functionally with product, engineering, and data teams to define search
requirements
Required Qualifications: • 5+ years of hands-on experience with Apache Solr or Lucene in production environments • Strong expertise in traditional relevancy engineering including query parsing, field
boosting, function queries, and relevance tuning • Proven experience conducting relevancy analysis using both automated metrics and
manual evaluation techniques • Strong expertise in vector embeddings and their application to semantic search • Proven experience building hybrid search systems that combine keyword and vector-
based approaches • Knowledge of search relevance metrics (NDCG, MRR, precision/recall) • Excellent problem-solving and analytical skills • Strong communication skills and ability to work in collaborative environments
