Pentest Security Engineer II, Devices

Pentest Security Engineer II, Devices & Services Pentesting

Job ID: 2858054 | Amazon Development Center Germany GmbH - C92

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 Devices and Services Trust & Security (DSTS) 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. 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 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.

Key job responsibilities

1. Lead and contribute to penetration tests against services and software released by Amazon’s Devices & Services organization. This includes working closely with builder teams to scope pentests, develop test plans, find vulnerabilities, develop proof of concept exploits, report findings, and validate patches.
2. Analyze and identify security vulnerabilities in source code using both automated and manual static analysis tools and techniques.
3. Review and influence technical solutions to mitigate security vulnerabilities by providing actionable long-term risk mitigation guidance to drive security improvements.
4. Lead impactful security improvements in large product lines through close collaboration with our partner builder teams.
5. Develop detailed technical documentation describing identified vulnerabilities, associated impact, and recommended remediation to guide communication with internal engineering stakeholders and leadership.
6. Mentor junior penetration testers and cultivate a culture of collaboration and research sharing.
