• Lead security implementation for AI tool and agent connectivity layers, including MCP gateway deployments, with controls for OAuth-based authorization, scope minimization, token audience validation, origin validation, replay protection, and secure isolation between trusted and untrusted tool domains.
• Deploy, build, and/or operate security infrastructure solutions to help scale and raise the security bar for Dropbox’s on-prem and cloud infrastructure.
• Automate security controls using scripting to eliminate redundant work and minimize need for human involvement.
• Collaborate with cross functional teams and lead security initiatives to influence product decisions and enhance security posture.

Virtual First

Dropbox’s Virtual First way of working is designed to help people do their best work with flexibility, autonomy, and connection. Day to day, teams work remotely with nonlinear schedules and core collaboration hours that support deep focus and individual working styles. We prioritize asynchronous communication to improve clarity, respect deep work time, and reduce unnecessary meetings. While remote work is the primary experience for our employees, we also prioritize intentional, in-person connection. We bring teams together through regular team gatherings, on-demand workspaces, and Dropbox Neighborhood events in order to strengthen team cohesion, foster creativity, and enhance momentum. Virtual First is built to provide the same access to opportunity, growth, and impact for everyone, regardless of location.

This role requires travel to offsites and various other team gatherings (approximately 5-10% of the year or 2-3 days per quarter). We provide advance notice when possible and encourage candidates to discuss any accommodation needs during the interview process.
