Application Security Engineer

About the Role

Role Description As part of the Product Security Engineering team, you’ll focus on reducing risk at scale by building the security infrastructure, automation, and tooling that empowers engineers to ship secure products with confidence. We work closely with engineering and product teams throughout the software development lifecycle (SDLC), embedding secure-by-default practices and delivering scalable solutions. Product Security Engineers create impact by implementing security tooling, writing custom security rules, and building frameworks that address broad classes of vulnerabilities. In addition to proactive development, we support teams through threat modeling, documentation, and education to uplift security culture across Dropbox. Our Engineering Career Framework is viewable by anyone outside the company and describes what’s expected for our engineers at each of our career levels. Check out our blog post on this topic and more here . Responsibilities Build and maintain security tools, automation, and libraries to enable secure-by-default development across engineering teams. Design and implement custom security rules (e.g., Semgrep, CodeQL) to detect and prevent common and emerging vulnerability patterns. Act as a subject matter expert on application security across web, mobile, and desktop environments. Improve and scale the Secure Development Lifecycle (SDLC) by integrating tools, checks, and processes into engineering workflows. Perform targeted code reviews, and develop follow-up tooling or controls to prevent regressions. Collaborate cross-functionally with engineering, product, GRC, and AI/ML teams to proactively address security risks, especially in fast-moving and emerging tech areas. Many teams at Dropbox run Services with on-call rotations, which entails being available for calls during both core and non-core business hours. If a team has an on-call rotation, all engineers on the team are expected to participate in the rotation as par
