• 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
