Security Engineer II, CLS Application Security

Love the idea of stopping security problems before they ever reach production — at a scale most engineers never get to touch? Come build automation and AI-powered tooling that protects the software behind Amazon's fulfillment, delivery, and grocery operations.We're a security team that cares about work-life harmony and meaningful work, and we invent novel ways to reduce risk at scale. You'll embed security early in the development lifecycle, partner directly with builder teams, and own a strategic project end to end while helping builders ship secure software faster. If you'd rather build a mechanism that prevents a whole class of vulnerabilities than review the same issue twice, you'll fit right in here.Key job responsibilities- Lead a strategic security initiative end to end — scoping, design, implementation, testing, deployment, and maintenance — while guiding other engineers along the way.- Build security automation and AI-powered tooling that scales beyond one-off reviews: prevention rules, secure defaults, and paved paths that stop vulnerabilities before they reach production.- Review application architecture and designs, leading security design reviews and steering builders toward secure-by-default solutions.- Consult directly with development teams, resolving findings and giving fast, actionable guidance that meets or exceeds the security bar.- Find opportunities to centralize controls so many teams can adopt one solution instead of each building their own, reusing what already exists wherever possible.- Dig into ambiguous, high-impact risks, spot patterns across a large application footprint, and fix root causes with reproducible mechanisms that are simple, maintainable, and built to last.- Communicate risk and recommendations clearly to engineers, partner security teams, and business stakeholders, and speak up for the right outcome even when it isn't the popular one.- Coach and mentor teammates to raise the bar on how the team works and the value it delivers.A day in the lifeMost days you'll split your time between the strategic project you own and the builders who need you. You might start by advancing your project — designing a piece of automation or AI tooling — then jump into a design review to help a team ship securely, or dig into a tricky consult where the right answer isn't obvious. You'll partner closely with development teams across our operations and grocery businesses, and with other security teams whose work connects to yours. When an urgent security issue comes up, you'll help contain it and make sure the fix sticks.About the teamWe embed security early in the development lifecycle, meeting builders where they are so issues get caught before they reach production. Our vision is a world where security is built in: guidance shows up right when builders need it, automation catches preventable issues, and our people focus on the risks that truly need human judgment. We live by a few tenets — automate to scale and save human expertise for judgment, design security in rather than bolt it on, prevent instead of react, and earn builder trust through clarity. We care about meaningful work and work-life harmony, and we have fun inventing.Diverse ExperiencesAmazon Security values diverse experiences.
