RAG Data Engineer

Join a culture of empowerment and connectivity.

Learn the skills you need to accelerate your career.

Discover benefits that support your life and work.

Build mission-ready tech that protects the nation.

As a RAG Data Engineer, you will build and operate the data ingestion and search infrastructure that powers mission-critical Retrieval-Augmented Generation (RAG) capabilities. You will design, implement, and maintain pipelines that transform structured and unstructured information into retrieval-ready assets, enabling AI-powered applications to deliver accurate, grounded, and relevant responses.

You will own the ingestion, embedding, and indexing workflows that connect enterprise data sources with Amazon Bedrock and Open Search. Your responsibilities will include document normalization, chunking strategies, embedding generation, metadata enrichment, lineage tracking, and reliable upsert or delete operations. You will also design and optimize Open Search indexes, mappings, shard configurations, lifecycle policies, and query performance.

Working alongside cloud architects, security engineers, application developers, and AI/ML specialists, you will help establish a scalable, secure, and resilient data retrieval foundation. Your work will directly support the development and deployment of enterprise RAG applications.

Work with us to use data for good.
