You will lead the development of human-LLM interaction capabilities, Retrieval-Augmented Generation (RAG) systems, and intelligent agents that operate at scale to support a variety of applications. This role will collaborate closely with internal stakeholders and external sponsors, including DoD organizations, to demonstrate and transition cutting-edge AI technologies into operationally relevant environments. As an AI & Decision Engineer, you will... Architect, develop, and evolve a Generative AI-powered analytical applications that support human-LLM interactions and LLM-driven decision-making at scale. * Design and implement LLM agents that can autonomously plan, reason, and act using tools such as RAG, analytical tools, and relevant databases. * Apply prompt engineering techniques with state-of-the-art models to produce data-driven recommendations based operational and developmental data for a variety of systems. * Design, implement, and manage RAG pipelines using vector databases and frameworks to integrate relevant documentation, prior analytical results, and large information repositories into LLM decision-making. * Develop and maintain agents capable of: (1) Interpreting database schemas and generating SQL queries to answer user questions (SQL agents). (2) Translating natural language inputs into structured actions and game events stored in a database for downstream simulation and adjudication. * Experiment with and evaluate prompting strategies to improve reasoning quality, robustness, and transparency of model outputs in high-consequence decision contexts. * Integrate orchestration and observability tools (e.g., Prefect) to monitor LLM pipelines, track outputs, and provide real-time insight into system behavior during wargame execution. * Fine-tune and adapt foundation models (e.g., Llama, Mistral) using AWS SageMaker, Hugging Face TRL, and synthetic data generation (e.g., GPT-4 series) to optimize performance on sponsor-specific tasks such as deductive coding, domain knowledge transfer, etc. * Engage with internal leadership and external sponsors to demonstrate capabilities, collect requirements, and potentially transition systems to operational users. * Document system architectures, experiments, evaluation results, and operational guidance prepare and present technical briefings and reports to technical and non-technical stakeholders. * Collaborate in multidisciplinary teams (AI/ML, software, human factors, operations analysts) to integrate AI capabilities into broader analytic and operational workflows., * This position may require occasional travel to sponsor sites and test events. * Candidates will be expected to work in multidisciplinary teams and contribute to both research and applied development efforts. * APL is committed to fostering an inclusive environment and encourages applications from diverse backgrounds. ## Related Videos - [How to Avoid LLM Pitfalls - Mete Atamel and Guillaume Laforge](https://www.wearedevelopers.com/videos/1328-how-to-avoid-llm-pitfalls-mete-atamel-and-guillaume-laforge) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Building and Deploying Multi-Agent Systems with ADK and Vertex AI](https://www.wearedevelopers.com/videos/1918-building-and-deploying-multi-agent-systems-with-adk-and-vertex-ai) ## Related Articles - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [What Are Large Language Models?](https://www.wearedevelopers.com/magazine/304-what-are-large-language-models) - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [What Industries Outside of AI Are Hiring The Most AI Experts?](https://www.wearedevelopers.com/magazine/98-what-industries-outside-of-ai-are-hiring-the-most-ai-experts) - [Got AI ideas but no money?
