CACI International Inc.; Northern (KY); Hybrid; USD 75,000 - 158,000; Part time

Job summary

CACI International Inc. is seeking an AI Engineer to design and deliver AI-based solutions for a federal workflow application. You will work across teams to translate business use cases into production-ready AI features, including chatbots, agentic workflows, and intelligent dashboards.

You will implement LLM-based capabilities, build robust RAG pipelines, and ensure responsible AI practices while maintaining full-stack skills in React, TypeScript, NodeJS, Python and Java.

Qualifications

• Bachelor’s degree in computer science or related STEM field.
• 5+ years of experience with software implementation across all aspects of the SDLC.
• 1+ years of hands-on experience developing generative AI / LLM-powered applications.
• Expert-level proficiency in Python; strong JavaScript proficiency.
• Experience with RESTful APIs and integrating AI/LLM APIs (OpenAI, Bedrock).
• Experience with prompt engineering techniques (few-shot, chain-of-thought, system prompts).
• Experience with LLM orchestration frameworks such as LangGraph, Agno, CrewAI, or similar.
• Experience with RAG architecture, agentic patterns, and vector databases.
• Strong understanding of ML fundamentals (supervised/unsupervised learning, model evaluation, feature engineering, NLP).
• Experience with data analysis and ML libraries (pandas, NumPy, scikit-learn, or equivalent).
• Experience with containerization (Docker) and at least one major cloud platform (AWS, Azure, or GCP).

Responsibilities

• Design and develop AI-enabled features for web-based workflow applications using LLMs, GenAI, and agentic AI patterns.
• Build RAG pipelines using application data, policy documents, user manuals, help cards and business process publications.
• Implement agentic workflows using orchestration frameworks for AI based application assistants.
• Implement prompt engineering strategies and integrate AI/LLM APIs (OpenAI, Bedrock).
• Architect full-stack AI features with reliable API integrations, error handling, and graceful degradation.
• Establish LLM observability (cost, latency, quality) and responsible AI guardrails (hallucination detection, output validation, CUI safeguards).
• Maintain full-stack applications (React, TypeScript, NodeJS, Python and Java).
• Address security vulnerabilities and ensure compliance with cybersecurity standards.
• Participate in code reviews, CI/CD pipelines, and collaborative development workflows.
• Document technical implementations and stay current with AI and ML developments.
