Principal Applied Scientist

Oracle Health Data Intelligence (HDI) uses data and AI to help healthcare and life sciences organizations turn complex information into useful insights and better decisions. Our teams build products for challenges across clinical, operational, and life sciences workflows.
We are seeking a Principal Applied Scientist to design and build production AI systems, with a particular focus on agents powered by large language models (LLMs). You will help determine how agents reason, use tools, retrieve information, and complete complex tasks reliably. This is a hands-on role for someone who can move from an ambiguous customer problem to a working product capability.
The ideal candidate brings strong experience with generative AI and LLM-based systems, along with the machine learning and statistical skills needed to evaluate them rigorously. You will work closely with engineering, product, and domain experts to make sound technical choices in an environment where accuracy, privacy, and trust matter.
