AI Developer Jobs in the United States

Application engineering on top of frontier models: agents, RAG, tooling and AI product surfaces.

AI Developer, United States…

An AI Developer builds applications on top of existing models rather than training new ones: agent loops, retrieval pipelines, tool use, evaluation harnesses and the product surfaces people actually touch. The role appeared as soon as frontier models became an API, and it is now how most companies add AI without a research team.
