Retrieval Engineer.

Core skills include vector database operations (Pinecone, Weaviate, Qdrant), embedding model selection and fine-tuning, chunking strategy design, and hybrid search combining dense and sparse retrieval. Understanding of reranking models, query expansion, and evaluation metrics like NDCG and recall is essential. Python and strong software engineering fundamentals are prerequisites.

Retrieval engineering extends traditional search with semantic understanding through embeddings. You still need classical IR knowledge (BM25, TF-IDF, inverted indices), but layer on vector similarity, embedding model management, and LLM-powered query understanding. The evaluation loop is also different because relevance is more subjective and context-dependent.
