Senior Pentest Security Engineer, Devices & Services Pentest

Come join our penetration testing team dedicated to the detection and exploitation of vulnerabilities affecting Amazon’s consumer services and devices. This includes conducting in-depth and low-level reviews of hardware, bootloaders, radios, secure enclaves, embedded systems as well as services 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 symbolic execution, fuzzing, machine learning, and static analysis.

The Amazon Devices and Services Trust & Security (DSTS) organization 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, incident response and remediations. We also drive down costs by building and automating security foundations and integrating them into design and release processes. DSTS 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.

The DSTS penetration testing organization is growing and seeking an experienced web service API and device penetration tester to help shape the future of Amazon’s service security. You will work with builder teams and product owners to triage penetration testing requests and identify high-impact security vulnerabilities across Amazon’s devices and services ecosystem. The ideal candidate will be expected to comprehend large complex web service architectures and to dive deep into a service's source code and also perform foundational hardware security penetration tests. This role will provide you with challenging technical opportunities and will also be a great deal of fun if hacking Amazon sounds exciting to you!

In this role, you will be part of a dedicated team of talented penetration testers identifying vulnerabilities in the devices and services ecosystem. You will strive to understand systems, software, and services deeply and develop creative ways to break assumptions in order to find vulnerabilities.
