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.
