  • RAG & Search Experience: Demonstrable, hands-on experience building or optimizing RAG pipelines. You must be comfortable with the theory and practice of hybrid search.
  • OpenSearch Proficiency: Strong practical knowledge of OpenSearch (or Elasticsearch), including query DSL, indexing strategies, and performance tuning for search relevance.
