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.
