About the role

Key responsibilities & impact

Design, develop, and deploy AI/ML models and pipelines that meet mission and performance objectives.
Build, train, and fine-tune models using frameworks such as PyTorch, TensorFlow, scikit-learn, Hugging Face, and LangChain.
Develop and operationalize MLOps pipelines (MLflow, Kubeflow, DVC, or custom training/inference orchestration).
Implement and optimize vector databases (Milvus, Pinecone, Chroma, FAISS) and retrieval architectures (RAG, graph, hybrid).
Write clean, efficient Python code for data ingestion, feature engineering, embeddings, and inference services.
Experiment with fine-tuning and optimization of LLMs and task-specific models (LoRA, QLoRA, PEFT).
Contribute to agent-based applications using frameworks like LangGraph, AutoGen, CrewAI, or DSPy.
Integrate AI services into real-world systems via APIs, event-driven workflows, or UI copilots.
Collaborate with data engineers, software developers, and mission analysts to ensure AI models are production-ready and aligned with customer needs.
Participate in peer reviews, contribute to shared repositories, and document models and experiments for reproducibility.

Requirements

What you’ll need

Must be a U.S. citizen and be willing to obtain and maintain a security clearance, as needed.
6-10+ years of professional experience developing and deploying AI/ML solutions in production environments.
Minimum of 3 years' professional experience within the Department of Defense/Department of War (DoD/DoW) AI assurance, security, and deployment environments.
Strong Python development skills with hands-on experience building AI/ML solutions.
Direct experience with ML frameworks such as PyTorch, TensorFlow, scikit-learn, Hugging Face, or LangChain.
Proven ability to build and deploy MLOps pipelines using MLflow, Kubeflow, DVC, or equivalent.
Working knowledge of vector databases (Milvus, Pinecone, Chroma, FAISS) and retrieval-based architectures (RAG, hybrid, graph).
Professional experience fine-tuning and evaluating LLMs or smaller task-specific models using LoRA, QLoRA, or PEFT.
Professional experience integrating AI capabilities into production systems or mission applications.
