RAG Engineer
You will architect retrieval-augmented generation pipelines, vector databases, and semantic search systems to ground AI in client truth.
What you'll work with.
As a RAG Engineer at TheWebVale, you will build retrieval-augmented generation systems that connect language models to private client knowledge bases. You will index documents, course materials, legal files, and medical records to generate grounded answers with verifiable source citations. You will partner with backend engineers and product owners during our two-to-three week sprint cycles. You will tune chunking strategies, optimize hybrid search accuracy, and deliver grounded AI applications that clients rely on for daily work.

Design end-to-end RAG architectures connecting LLMs to proprietary client documents.
Implement intelligent document parsing and chunking for PDFs, spreadsheets, and HTML.
Configure vector databases including Pinecone, Qdrant, or PGVector for semantic retrieval.
Implement hybrid search combining dense vector similarity with BM25 keyword matching.
Integrate cross-encoder rerankers like Cohere to improve retrieved chunk relevancy.
Measure retrieval quality using context recall, precision, and faithfulness benchmarks.
