About The Opportunity

Our client, a leader in AI testing and Generative AI solutions, is looking for a skilled Context/Retrieval Engineer (RAG Specialist) to join their team for a 12-month engagement. This project involves optimizing Retrieval-Augmented Generation (RAG) pipelines to improve the accuracy and relevance of AI responses. This is a high-impact role that requires a self-motivated professional who can hit the ground running and deliver results quickly.

Key Responsibilities & Deliverables

This role is focused on the successful completion of specific tasks and deliverables. Your responsibilities will include:

• Optimizing Retrieval-Augmented Generation (RAG) pipelines to improve the accuracy and relevance of AI responses.

• Implementing advanced "chunking" strategies and metadata tagging for enterprise documents.

• Selecting and fine-tuning embedding models to better capture domain-specific semantic meaning.

• Designing hybrid search systems combining vector similarity with traditional keyword search (BM25).

• Benchmarking various vector databases to ensure high retrieval speed and low memory overhead.

• 3+ years of experience in Information Retrieval or AI Engineering.

• Deep expertise in Vector Databases (Pinecone, Chroma, Milvus) and LangChain/LlamaIndex. This isn't a learning role—you need to be a subject matter expert.

• Demonstrated ability to work autonomously and manage your own time effectively to meet project goals.

• Experience with Python, SQL, and natural language processing (NLP) techniques.

• Strong communication skills to provide clear and concise status updates to the project team.
