As a RAG Application Engineer, you will build the application layer that makes this possible.
Retrieval-Augmented Generation (RAG) systems require reliable, well-orchestrated runtime logic to integrate search, models, and metadata into a single coherent experience. As a RAG Application Engineer, you will build the application layer that makes this possible. You will implement the end-to-end query workflow, including embedding generation, hybrid retrieval, reranking, citation assembly, and request-level guardrails, ensuring analysts can access grounded, high-quality responses at scale.
We're looking for an engineer who can design and maintain RAG runtime logic in a secure, cloud-based environment. On our team, you'll develop API endpoints, manage model integrations, enforce authentication and authorization controls, and implement robust retry, timeout, and error-handling strategies.
You'll containerize services and partner closely with Cloud, Security, Data, and Site Reliability Engineering teammates to ensure the RAG runtime is stable, secure, observable, and ready for mission use.
Join us. The world can’t wait.
