Description Come join our penetration testing team dedicated to the detection and exploitation of vulnerabilities across Amazon’s portfolio ranging from consumer services and devices to the Kuiper satellites. This includes conducting in-depth reviews of complex service workflows including authentication mechanisms, AI, mobile, web applications, and web service APIs. Pentesters also invent new ways to automate and improve their work with techniques such as AI/LLMs, fuzzing, detection at scale, and static analysis. Our team operates under the Amazon Specialized Businesses Security (SBS) organization which was formed in 2014 with the mission of protecting Amazon Devices & Services (D&S) customers’ trust, data, and the systems on which they rely. We protect customers by performing security reviews, offensive testing, vulnerability assessments, and provide guidance for remediations. We also drive down costs by building and automating security foundations and integrating them into design and release processes. SBS builds the foundational capabilities that raise an org-wide security bar across the growing diversity of D&S businesses - securing 100+ device types, 12,000+ applications, and 100+ product lines that are developed and operated by more than 16,000+ builders.
