About The Position

CACI is looking for an AI Prompt Engineer to join our EITaaS contract. We are seeking a highly creative, technically proficient, and detail-oriented Prompt Engineer to join our growing AI team. This pivotal role will be responsible for designing, testing, and optimizing prompts for Large Language Models (LLMs) to achieve high-quality, and reliable outputs for various use cases. You will be instrumental in translating complex requirements into effective AI interactions. This role is ideal for someone who thrives on experimentation, understands how LLMs interpret language, and is passionate about unlocking the full potential of generative AI.

Requirements

• US Citizenship.
• A DoD secret clearance or ability to obtain.
• Bachelor’s degree in computer science, Software Engineering, Information Technology, or related field (equivalent experience may be considered in lieu of degree).
• 6+ months of professional software development experience, internships, or relevant academic project work.
• 1+ year of hands-on experience working with Large Language Models (e.g., OpenAI GPT series, Llama, Gemini) or other generative AI models.
• Experience with at least one programming language (Python, JavaScript/TypeScript)
• Familiarity with prompt engineering techniques (few-shot, chain-of-thought, structured outputs, function calling)
• Problem-solving skills, with a data-driven approach to experimentation and optimization.
• Witten and verbal communication skills, with an ability to articulate complex technical concepts clearly.
• Ability to work independently and collaboratively in a fast-paced, evolving environment.

Nice To Haves

• Understanding of AI safety considerations (e.g., prompt injection, bias, data privacy)
• Exposure to Agile/Scrum development environments
• Experience with ServiceNow

Responsibilities

• Develop, refine, and iterate on prompts for various generative AI models (LLMs) to elicit desired behaviors, responses, and creative outputs.
• Conduct testing to compare prompt variations, analyze results drive continuous improvement.
• Work closely with multiple groups to integrate prompts to streamline manual processes.
• Stay abreast of the latest advancements in LLMs, generative AI, and prompt engineering techniques.
• Provide input and collaborate on strategies for model fine-tuning and Retrieval Augmented Generation (RAG) to further improve accuracy.
• Debug unexpected model behaviors, identifying root causes within prompt structure, model limitations, or data context.

Benefits

• flexible time off benefit
• robust learning resources
• comprehensive benefits such as; healthcare, wellness, financial, retirement, family support, continuing education, and time off benefits.
