Security Engineer, Internal Audit

We are seeking a Security Engineer II to join our mission of protecting customer data and keeping Amazon secure. In this role you will be working to secure multiple Amazon businesses across the Devices, Media & Entertainment, Advertising, Alexa, and Corporate spaces. You will partner 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 your skills in vulnerability assessment, exploitation, penetration testing, and red teaming to identify and mitigate risks. 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. You will be exposed to the full breadth of technology used across Amazon and its subsidiaries, influence security architectures, 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 coupled with the ability to operate independently and as part of highly-skilled teams.

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


About the team
Our security team executes independent assessments of the efficacy of Amazon's layered security controls. We prioritize security assessments of systems and processes that may impact foundational technologies, human safety, privacy and durability of customer data, and financial systems. We believe active tests are required to assess complex environments and emphasize custom tooling to enable safe operation at scale.
