Principal Software Engineer, Identity & Engagement

About

Dropbox is hiring a Principal Software Engineer, Identity & Engagement to drive the technical direction and execution of the core services that power Dropbox’s product ecosystem. This includes mission-critical infrastructure across identity and access, engagement and insights platforms, foundational APIs, and the core cross-product services that underpin everything from user onboarding to advanced AI-powered workflows.

In this role, you’ll serve as a senior technical leader—setting architecture, raising the engineering bar, and shipping high-impact platform capabilities used across Dropbox.
