You will work alongside cross-functional teams supporting critical missions within the Intelligence Community, applying cutting-edge AI/ML techniques to drive insights and decision-making in secure environments.

Key Responsibilities:

• Design and implement secure, on-premises LLM infrastructure and pipelines tailored to mission needs

• Evaluate, fine-tune, and deploy open-source or custom LLMs within air-gapped environments

• Develop and manage data pipelines for ingesting and processing structured and unstructured datasets at scale

• Apply NLP, ML, and data science techniques to extract insights from massive datasets (millions+ records)

• Collaborate with analysts, engineers, and mission stakeholders to shape AI capabilities around operational requirements

• Ensure compliance with security and data governance standards for classified environments

• Monitor model performance, implement updates, and optimize compute usage

Basic Qualifications:

• Active TS/SCI clearance with CI Polygraph

• 5+ years of experience in AI/ML engineering, data science, or software development

• Hands-on experience deploying or fine-tuning LLMs (e.g., LLaMA, Mistral, GPT-NeoX, BERT, etc.)

• Experience with on-prem or air-gapped AI/ML deployments, including containerized or GPU-based environments

• Strong proficiency in Python and common ML/NLP libraries (e.g., Hugging Face Transformers, PyTorch, LangChain)

• Experience working with large datasets (millions of records), including ETL and data transformation pipelines

• Solid understanding of system architecture, data privacy, and secure computing practices

Preferred Qualifications:

• Experience deploying quantized models for performance optimization (e.g., using llama.cpp, ggml, gguf)

• Familiarity with GPU server infrastructure (e.g., NVIDIA A100/RTX, CUDA) or multi-node compute setups

• Knowledge of cloud-to-on-prem transition architectures

• Background in supporting Intelligence Community or DoD missions
