The Opportunity

We are seeking a highly skilled Information Retrieval Engineer to lead the development and optimization of retrieval systems that power context-aware large language models (LLMs). This role focuses on building robust Retrieval-Augmented Generation (RAG) pipelines to ensure AI agents and applications have access to the most relevant, timely, and high-quality information.

You'll work at the intersection of data engineering, machine learning, and knowledge management—enabling better reasoning, accuracy, and performance for enterprise-grade AI systems.

What you'll Do

RAG System Design

• Architect and deploy scalable retrieval pipelines using vector databases (e.g., FAISS, Weaviate, Pinecone, Qdrant)
• Implement semantic search infrastructure and hybrid retrieval systems (semantic + keyword)

Data Processing & Ingestion

• Build ingestion pipelines for both structured and unstructured data sources
• Implement document chunking strategies, embedding generation (e.g., OpenAI, Cohere, HuggingFace), and metadata tagging

Retrieval Optimization

• Fine-tune relevance scoring, reranking algorithms, and query understanding mechanisms
• Develop techniques to improve precision/recall for specific business domains or user tasks

Knowledge Enhancement

• Create and maintain knowledge graphs to support context linking and disambiguation
• Manage data freshness and version control to ensure consistency and reliability of retrieved content

Reasoning Support

• Design and iterate on context window strategies that improve LLM reasoning (e.g., adaptive injection, task-based retrieval)
• Collaborate with prompt engineers and model developers to align retrieval outputs with downstream model behavior

Performance Monitoring

• Track key retrieval metrics such as accuracy, latency, and fallback rate
• Implement caching, prefetching, and deduplication strategies to optimize system responsiveness

What you need to succeed

• 4+ years in data engineering, ML infrastructure, or information retrieval
• Experience building and deploying RAG pipelines or semantic search systems
• Strong ML and Python skills and familiarity with retrieval libraries (e.g., Haystack, LangChain, Elasticsearch, Milvus)
• Proficiency with embedding models, vector similarity search, and document indexing
• Familiarity with cloud platforms and MLOps tooling (e.g., Airflow, dbt, Docker)

Preferred Qualifications

• Knowledge of graph databases (e.g., Neo4j, TigerGraph) or knowledge graph design
• Experience optimizing retrieval for LLMs (e.g., OpenAI, Anthropic, Mistral)
• Background in IR/NLP, Search Engineering, or Cognitive Computing
• Degree in Computer Science, Information Systems, or a related field
