About The Position

CACI is seeking an AI Subject Matter Expert in support of the Bureau of Diplomatic Security (DS) to drive the design, evaluation, and adoption of AI solutions across the organization. This role will emphasize applied AI, including identifying practical use cases, advising on model and tool selection, guiding responsible deployment, and communicating AI capabilities and limitations to both technical and non-technical audiences.

Experience designing or advising on real-world AI use cases.
Ability to clearly explain AI concepts to both technical and non-technical audiences.
Experience evaluating the risks and limitations of AI systems.

Nice To Haves
