* Familiarity with LangChain for building LLM workflows using tools, memory, and retrieval.

Day-to-Day:
We are hiring two AI/LLM Engineers (1 Mid-Level, 1 Senior) to join a small, focused team building backend features for an existing Retrieval-Augmented Generation (RAG) service. You'll work on extracting structured data from diverse content types—images, graphs, eBooks, journals, and more—using visual-based models. This role involves experimentation, model development, and comparing LLMs for visual RAG use cases. You’ll deploy code to non-prod environments and support production rollout in collaboration with the DevOps team. While primarily a heads-down, individual contributor role, clear communication and collaboration with the team is expected.
