Applied Scientist, AI Security

We are seeking an Applied Scientist to join our AI Security team which builds AI-based security analysis services that identify validate and help remediate vulnerabilities in Amazon source code and cloud configurations. The team combines large language models security knowledge code analysis and security-engineer feedback to help builder teams detect security issues earlier in development and maintain security coverage across Amazon.

As an Applied Scientist you will research model design and implement machine learning and agentic systems that reason over source code infrastructure and security context. You will collaborate with applied scientists security engineers software engineers internal partners and external researchers to improve finding precision severity assessment remediation quality and continuous scanning coverage. Your work will enable continuous AI-driven security analysis across Amazons software estate converting source-code and infrastructure signals into validated prioritized findings and proposed fixes that help builders prevent security defects from reaching production.

Key job responsibilities
Research and develop accurate and scalable methods to solve our hardest AI security problems
Lead cross-functional work with applied scientists software engineers and security engineers to develop models and technical designs for AI systems that analyze source code validate security findings and generate remediation guidance at Amazon scale.

About the team
As an Applied Scientist on the AI Security team you will research develop evaluate and productionize models that identify security vulnerabilities in source code and cloud configurations. You will design experiments build evaluation datasets and metrics and apply large language models program analysis and security knowledge to improve finding precision severity assessment and remediation quality. You will work with applied scientists security engineers and software engineers to deliver systems that convert security signals into validated prioritized findings and proposed fixes for builder teams across Amazon.

Your work will shape how Amazon identifies and addresses security defects throughout the software development lifecycle. You will investigate model behavior analyze failure modes develop methods to improve recall and precision and measure the impact of new capabilities before deployment. The role provides opportunities to solve applied machine learning problems across source code infrastructure cloud services and security operations.
