About The Position

CACI is seeking a visionary AI Engineering Lead to support the Department of Homeland Security (DHS) Office of the Inspector General (OIG). This role offers a unique opportunity to provide technical leadership and strategic direction for an enterprise AI transformation that strengthens national security oversight through investigative, audit, and inspection operations. As the AI Engineering Lead, you will architect and oversee the implementation of AI capabilities across the DHS OIG enterprise, from OIGChat—a large language model assistant—to mission-specific investigative analytics applications. You will lead technical teams, define AI architecture patterns, establish model governance frameworks, and ensure responsible AI practices across all implementations. You will coordinate access to Azure OpenAI and Azure AI Foundry services, implement cost controls and guardrails, and provide expert guidance on complex AI problem sets from prototype through production. Working within secure government cloud environments, you will shape the technical vision and execution strategy for AI capabilities on a transformational program of national importance. Join us to make a meaningful impact by leading the future of AI-enabled federal oversight.

• Proven technical leadership experience architecting and delivering enterprise-scale AI/ML solutions, with demonstrated ability to lead engineering teams and coordinate cross-functional efforts
• Deep expertise in large language models (LLMs), generative AI, Azure OpenAI/Azure AI services, and enterprise AI platforms with understanding of model governance, responsible AI, and production ML operations
• Extensive experience designing AI architectures, including RAG (Retrieval-Augmented Generation), model routing, API patterns, guardrails, monitoring, cost optimization, and integration with enterprise data platforms
• Strong background in AI/ML frameworks (LangChain, Semantic Kernel, TensorFlow, PyTorch), Python development, and cloud-native AI services with ability to provide hands-on technical guidance

Nice To Haves

• Experience leading AI initiatives in federal government, law enforcement, investigative, or national security environments with understanding of sensitive data handling, ATO processes, and compliance requirements
• Hands-on experience with MLOps, model lifecycle management, AI governance frameworks, and production AI monitoring and observability tools
• Background in investigative analytics, fraud detection, text analytics, NLP, or mission-driven AI applications supporting oversight, audit, or law enforcement functions

Responsibilities

• Provide technical leadership and architectural direction for all AI capabilities, including OIGChat, pilot applications, and enterprise AI platform services across Azure Government and Commercial environments
