The Opportunity:

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.

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

Oversee secure, governed access to Government-approved AI models (Azure OpenAI, Azure AI Foundry, commercial LLM providers), including model selection, routing architecture, API management, and integration patterns

Lead design, development, and architecture of mission-specific AI applications for investigative analytics, hotline analysis, eDiscovery, and oversight use cases from concept through production

Establish and enforce model governance, cost management, and responsible AI frameworks, including usage monitoring, token consumption tracking, dashboards, thresholds, alerts, and guardrails to prevent unauthorized use, excessive cost, and data leakage

Define and implement AI/ML architecture patterns that ensure all model access consumes governed, authoritative datasets from the enterprise data platform in compliance with data governance, classification, and quality policies

Lead solution architecture and prototyping efforts, providing expert guidance on complex AI problem sets, technical feasibility assessments, and level-of-effort estimates

Coordinate AI workload requirements and scalability planning across infrastructure, data, and application layers to support current and future AI use cases

Lead and coordinate AI engineering and data science resources, including surge support for specialized technical analysis, model development, validation, and production deployment

Support model auditing, explainability, bias detection, and compliance with federal AI requirements and DHS OIG data governance policies

Collaborate with Government leadership, platform engineers, security specialists, and product teams to align AI capabilities with mission priorities, Agile delivery processes, and enterprise architecture standards.

Qualifications:

Required – 

Bachelor's degree + 15 years of experience in artificial intelligence, machine learning, software engineering, or related field; equivalencies considered (Master's + 12 years; 21 years with no degree; AA + 17 years)

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

Desired –

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
