- Assess security controls around Amazon's adoption of AI/ML technologies — including model access, training data protection, output integrity, and integration into development workflows — to ensure they result in secure customer experiences
- Build reusable security frameworks, runbooks, and rubrics that enable the team to assess new problem domains repeatably and at scale
- Communicate security risk findings and recommendations clearly to technical teams and senior leadership
- Mentor and develop other security engineers; lead engagements requiring coordination across multiple engineers and teams
