Security Engineer, Security Verification & Validation Team

ph3Description /h3 pWe are looking for a Security Engineer to join Point-in-Time Security Testing, AWS's expert security assurance function for the launches and architectures where security automation alone is not enough. You will own complex security testing engagements end to end, and you will leave behind mechanisms that make each engagement worth more than itself. /p h3Description /h3 pWe are looking for a Security Engineer to join Point-in-Time Security Testing, AWS's expert security assurance function for the launches and architectures where security automation alone is not enough. You will own complex security testing engagements end to end, and you will leave behind mechanisms that make each engagement worth more than itself. /p pAmazon Web Services (AWS) is the leading cloud service provider, providing virtualized infrastructure, storage, networking, messaging, and many other services to customers all over the world, including government customers. AWS runs a globally distributed environment operating at massive scale, and businesses from start-ups to large enterprises and governments run their most sensitive workloads on it. Point-in-Time Security Testing takes on the engagements where the architecture, threat model, or potential impact is complex enough that expert reasoning matters most. We start from the architecture and the risks rather than a generic checklist, think like an adversary, and demonstrate realistic impact. We build harnesses that steer agentic AI so experts have more time for the difficult problems, and we turn what we learn into shared methods, mechanisms, and detections for the rest of the team. As AWS ships agentic systems of its own, those same systems become targets we test. /p pOur work is measured by how much difficult security uncertainty we resolve with the human time available to us, not by how many issues we find. In this role you will investigate high-consequence risks, which are specific, testable claims about how an adversary could cause harm, and take each one to a documented conclusion. You will either demonstrate the issue, rule out the attack path with enough evidence, or expose a weakness in a shared mechanism or detection. /p pYou must produce results in the face of ambiguity and imperfect knowledge, foster constructive dialogue, and drive resolution when faced with disagreement. You deliver autonomously on work scoped within the team, and you ask for guidance when a problem crosses into unfamiliar territory. You are trusted to run a difficult engagement without close supervision, and to say clearly when the plan needs to change. /p pAmazon's Leadership Principles of "Dive Deep", "Earn Trust", "Deliver Results", and "Invent and Simplify" will be called upon daily. Above all, we earn trust by choosing carefully where humans spend time, testing those areas deeply, and being honest about what we know and what we do not. /p h3Key job responsibilities /h3 ul liLead complex security testing engagements end to end, including multi-engineer tests across interconnected microservice architectures, repeat testing across successive iterations of one launch, and campaigns that investigate a systemic issue across several services /li liPerform penetration testing and AI-augmented source code review of complex proprietary AWS software, directing the tooling at trust boundaries, abuse cases, and attack paths it would not reach on its own, and confirming what it reports /li liTake each agreed risk hypothesis to a documented conclusion, whether that means demonstrating the issue with proof-of-concept code, ruling out the attack path with sufficient evidence, or identifying a weakness in a shared mechanism or detection /li liChallenge what a scope document assumes and identify what it misses, then keep the engagement moving when conditions change by building alternative test paths, re-scoping, and parallelizing work with dependent teams /li liTrace attack paths across chained components and demonstrate compound risk that stays invisible when components are tested in isolation /li liAssess and defend the business impact of complex and ambiguous risk, not only well-understood vulnerability classes, so service teams can act on the right things first /li liProduce clear engagement results that record what you tested, why you chose those tests, what you found or ruled out, the limitations of the work, and the risk that remains /li liLead communication with developers, AppSec engineers, and Blue teams when the scope is ambiguous or a fix is not straightforward, validate the fixes, confirm remediation through Verification of Fixes, and work as an embedded security tester inside the development lifecycle when a launch calls for it /li liBuild automation and tune the harnesses that raise the precision of the team's AI pentest bots, measuring where they produce false positives or miss attack patterns, so expert time goes where it changes the outcome /li liTest agentic AI systems as an adversary would, reasoning about how agent-to-agent (A2A) communication, tool use, memory, and orchestration can be manipulated or made to cross a trust boundary /li liLeave reusable mechanisms behind, such as fuzzers, integration security tests, detection rules, tooling, or documented methodology, and track whether they are adopted /li liPeer review test plans, scopes, runbooks, and reports from other peers, questioning coverage gaps and adding the test cases that are missing /li liOnboard and mentor engineers on your engagements, helping them grow technically while the engagement stays on track /li /ul h3About The Team /h3 pWhy AWS Security? /p pAt Amazon, security is central to maintaining customer trust and delivering delightful customer experiences. Our organization is responsible for creating and maintaining a high bar for security across all of Amazon's products and services. We offer talented security professionals the chance to accelerate their careers with opportunities to build experience across cloud, devices, retail, entertainment, healthcare, operations, and physical stores. /p pPoint-in-Time Security Testing sits within Proactive Security. While the wider organisation builds the ability to find risk through signals, automation, AI, Bug Bounty, and continuous testing, our role is different. We take on the situations where expert reasoning matters most, and we make that expertise go further every year. Our vision is that every critical AWS launch receives the right depth of expert security testing, and every hour our team spends makes future testing more effective. /p h3Diverse Experiences /h3 pAmazon Security values diverse experiences. Even if you do not meet all of the qualifications and skills listed, we encourage you to apply. If your career is just starting, hasn't followed a traditional path, or includes alternative experiences, don't let it stop you from applying. /p h3Inclusive Team Culture /h3 pIn Amazon Security, it's in our nature to learn and be curious. Ongoing DEI events and learning experiences inspire us to keep learning and to embrace our uniqueness. Addressing the toughest security challenges requires that we seek out and celebrate a diversity of ideas, perspectives, and voices. /p h3Training Career Growth /h3 pWe're continuously raising our performance bar as we strive to become Earth's Best Employer. You'll find endless knowledge-sharing, mentorship, training, and other career-advancing resources here to help you develop into a better-rounded professional. /p h3Work/Life Balance /h3 pWe value work-life harmony.
