Pentest Security Engineer, Specialized Pentest Team, Devices & Services

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.

• Contribute to penetration tests against services and software released by Amazon’s Devices & Services organization, working closely with builder teams to find vulnerabilities, develop proof‑of‑concept exploits, report findings, and validate patches.
• Analyze and identify security vulnerabilities in source code using both automated and manual static analysis tools and techniques.
• Review and influence technical solutions to mitigate security vulnerabilities by providing actionable long‑term risk mitigation guidance.
• Provide impactful security contributions to large product lines through close collaboration with partner builder teams.
• Develop detailed technical documentation describing identified vulnerabilities, associated impact, and recommended remediation to guide communication with internal engineering stakeholders and leadership.
• Continuously grow and develop technical skillsets while contributing to standing projects for program improvement in DSPT.
