We are looking for a Senior 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 be a technical leader on a team, owning complex security testing engagements end-to-end, applying human judgment where it changes security outcomes and building automation for everything else.Amazon 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 security 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.Our 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.You must produce results in the face of ambiguity and imperfect knowledge, foster constructive dialogue, and drive resolution
