Role Description

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. You’ll partner closely with engineering leaders, product, design, security, and infrastructure teams to modernize systems, improve reliability and developer velocity, and unlock smarter user experiences.

The future of work is being built on strong Identity & Engagement, and Dropbox is doubling down on platform investments to accelerate AI-driven innovation and deeper customer value.
