AI Prompt Engineer

CDIT LLC is seeking a highlycreative, technically proficient, and detail-oriented AI Prompt Engineer tojoin a growing AI team supporting a federal border security mission. This roleis responsible for designing, testing, and optimizing prompts for LargeLanguage Models (LLMs) to produce high-quality, reliable outputs across a rangeof mission use cases — translating complex requirements into effective AIinteractions, within an Agile delivery environment.

•     Prompt Design & Optimization — Develop,refine, and iterate on prompts for generative AI models (LLMs) to elicitdesired behaviors and outputs.

•     Iterative Testing & Analysis — Conductstructured testing to compare prompt variations and drive continuousimprovement.

•     Collaboration — Work closely withcross-functional teams to integrate prompts that streamline manual processes.

•     Fine-Tuning & RAG Support — Provide input onmodel fine-tuning and Retrieval-Augmented Generation (RAG) strategies.

•     Problem Solving — Debug unexpected modelbehaviors, identifying root causes in prompt structure or data context.

•     Must be a U.S. Citizen with the ability to passa federal background investigation (criminal, drug use, and misconduct checks).

•     Bachelor's degree in Computer Science, SoftwareEngineering, IT, or related field (equivalent experience considered)

•     1+ year of hands-on experience with LLMs (e.g., OpenAIGPT series, Llama, Gemini)

•     Proficiency in at least one programming language(Python, JavaScript/TypeScript)

•     Familiarity with prompt engineering techniques(few-shot, chain-of-thought, structured outputs, function calling)

•     Strong, data-driven problem-solving skills

•     Strong written and verbal communication skills

•     Exposure to RAG concepts, embeddings, and vectordatabases

•     Understanding of AI safety considerations (promptinjection, bias, data privacy)

•     Exposure to Agile/Scrum environments
