AI Engineer
First seen by Alion on Oct 21, 2026. CACI International scores D on the Alion truth index.
The Opportunity:
We are seeking an AI Engineer to design, develop, test, and support AI-enabled applications and agent-based solutions to support the United States Secret Service (USSS) contract supporting the Department of Homeland Security. The engineer will work across the software development lifecycle, translating mission and user needs into secure, reliable capabilities that integrate AI models with enterprise data, applications, and workflows. The work may use frameworks such as LangChain and Microsoft Agent Framework, along with cloud-based AI services and established software engineering practices.
The AI Engineer will collaborate with product, functional, data, cybersecurity, and infrastructure teams to develop practical solutions that meet user needs and enterprise requirements. The role includes building and evaluating capabilities such as retrieval-augmented generation (RAG), tool and API integrations, and agent workflows; improving system quality through testing and user feedback; and supporting deployment, monitoring, and continuous improvement.
