About The Position

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.

The SBS penetration testing organization is growing and seeking an experienced
web penetration tester to help shape the future of Amazon’s service security.
You will work with builder teams and product owners to perform penetration
testing and identify high-impact security vulnerabilities across the web
services ecosystem supporting Amazon’s devices. The ideal candidate will be
expected to comprehend large complex web service architectures and to dive deep
into a service's source code, and to have some exposure to device 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. You care
deeply about keeping millions of customers that rely on Amazon’s consumer
products safe and are passionate about mitigating vulnerabilities by providing
actionable guidance to product teams. You're well-known for your excellent
prioritization skills as well as your ability to communicate at all levels of an
organization. If you're passionate about finding security bugs, writing tools to
enhance manual testing capabilities, automating repetitive tasks, and enjoy
seeing your work impact Amazon consumer devices and services, then this position
is for you. Candidates from mid to senior level are encouraged to apply.
