• Develop and tune relevance models using query analytics, behavioral signals, and experimentation frameworks to improve search outcomes.

• Integrate Generative AI capabilities with traditional information retrieval systems to create intelligent, context-aware search experiences.

• Implement and optimize Retrieval-Augmented Generation (RAG) pipelines that combine structured and unstructured enterprise data sources.

• Partner with AI engineers, platform teams, and product stakeholders to define measurable improvements in search quality and user satisfaction.

• Bachelor's degree in Computer Science, Information Retrieval, Data Science, or related field with 5+ years of experience in search engineering or relevance optimization.

• 3+ years of hands-on experience designing and operating Elasticsearch in production environments.

• Demonstrated experience tuning search relevance (ranking, scoring models, analyzers, tokenization, synonyms, boosting).

• Experience working with large-scale structured and unstructured data sets.

• Proficiency in Python, Java, or similar programming language for search and data processing applications.

• Experience integrating Generative AI or LLM-based systems with search platforms.

• Familiarity with Retrieval-Augmented Generation (RAG) frameworks and vector search techniques.

• Experience with hybrid search (keyword + vector search) and embedding-based retrieval systems.

• Knowledge of evaluation metrics such as NDCG, MRR, precision/recall, and A/B testing for search optimization.

• Strong communication skills with the ability to translate search relevance improvements into business impact.
