Senior Security Engineer, Internal Audit

Description

Amazon's Internal Audit Security team is seeking a Security Engineer III to join our mission of protecting customer data and keeping Amazon secure. You will operate as a security lead, partnering with world-class engineering teams to uncover vulnerabilities, design novel abuse scenarios, and assess large-scale security solutions across Amazon's products, services, and infrastructure.

In this role, you will leverage deep expertise in vulnerability assessment, exploitation, penetration testing, and red teaming to identify and mitigate risks across large, ambiguous problem spaces. Your work will span source code analysis, network penetration, and application exploitation. You will design, implement, and execute methodologies for security assessments of critical Amazon systems. Additionally, you will construct security frameworks, runbooks, and rubrics that enable others to apply your work in a repeatable manner. You will be exposed to the full breadth of technology used across Amazon and its subsidiaries, influence security architectures, identify opportunities to centralize security controls across the company, and communicate risks to Senior Executives. As AI accelerates development across Amazon, you will both leverage AI to enhance our audit capabilities and assess the security controls governing its use.

This role requires technical depth, strong security judgment, and the ability to lead projects spanning multiple engineers and teams. You will set a culture of robust security best practices, mentor and develop other security engineers, and drive long-term, measurable security risk reduction while balancing business need and customer experience.

Key job responsibilities

• Lead independent security audits of Amazon systems, services, and infrastructure to assess whether security controls are effective

• Identify security risks through penetration testing, design reviews, threat modeling, and code analysis

• Investigate security control failures - determine why preventive or corrective controls didn't work, and drive root-cause resolution across team boundaries

• 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
