AI Researcher - Entry to Expert Level (Maryland)

Summary

As an AI Researcher at NSA, you will investigate, characterize, and extend what AI systems can do for the mission. The work spans rigorous evaluation and method development (benchmarking, training approaches, model analysis) through applied prototyping that turns emerging capabilities into working tools. You may be assigned to a research organization, embedded with a mission element, or enrolled in a development program that rotates you through several.

Duties

AI Research at NSA is a specialized discipline that intersects machine learning, experimental science, and software prototyping. AI Researchers answer open questions about AI system behavior, develop the methods and adaptations that make those systems effective under Agency data and constraints, and build the prototypes that demonstrate new capabilities. Individual researchers lean toward evaluation, method development, or applied prototyping based on background and assignment; most projects draw on all three. Responsibilities include: - Design and run experiments that characterize AI system capability, behavior, and failure modes; build benchmarks and evaluation methodology where none exist. - Develop training, fine-tuning, retrieval, and inference techniques suited to Agency data, scale, and security constraints. - Prototype novel AI applications and agentic systems that put emerging capabilities in analysts' hands, and iterate them based on user feedback. - Investigate model internals, robustness, and safety, including how AI systems can be attacked, manipulated, or induced to fail. - Assess vendor, open-source, and internally developed AI systems against government baselines and mission requirements. - Track the external state of the art and provide critical, evidence-based assessments of new models and techniques. - Communicate results through technical reports, briefings, prototypes, and internal publications; mentor junior researchers and interns.
