Job description
from Amazon careersAmazon Integrated Security is seeking a Principal Applied Scientist to lead research at the intersection of cognitive psychology, measurement science, and AI security. This role will pioneer new approaches to understanding and leveraging behavioral characteristics of autonomous AI systems in security contexts, turning threat actor use of AI into a structural advantage for defenders.
Key job responsibilities
Establish and lead a novel research program exploring cognitive patterns and biases in agentic AI systems used for offensive security purposes. Design and conduct experiments to understand black-box AI system behavior, develop measurement frameworks for previously unmeasurable security concepts, and translate research findings into actionable defensive strategies and tooling. Create feedback loops between offensive and defensive security teams, collaborate with threat intelligence experts and red team operations, and publish findings that advance both academic understanding and practical security outcomes. Apply measurement science expertise to quantify complex security concepts including risk, business impact, and trust.
A day in the life
Work closely with a Principal Technologist with AI and security expertise, senior security engineers with threat intelligence backgrounds, offensive AI security teams, and detection/response operations. Mentor junior scientists and engineers while maintaining strong connections with academic research communities.
