Role Description Dropbox’s Design team is looking for a Principal Designer to help define the future of content activation for Dropbox customers. In this role, you will help lead the design vision and execution for Dropbox’s portfolio of products and services. As a Principal Designer, you will shape how AI helps customers get their jobs done faster, better, and with greater confidence. Dropbox holds the content, context, and collaboration that power our customers’ most important work. This role is about designing AI experiences that activate that content in useful, intuitive, and trustworthy ways, helping customers find clarity, make progress, and take action without adding complexity or friction. We believe AI should sharpen our customers, not replace their judgment. You will be responsible for creating experiences where AI acts as a thoughtful partner: surfacing what matters, reducing busywork, connecting ideas, and helping people move from information to action, while keeping customers in control. The best experiences will feel elegant, precise, and almost invisible; AI should make Dropbox more powerful without making it feel more complicated. This role requires a designer with exceptional craft, strong product judgment, and the ability to operate across strategy, systems, and execution. You will translate emerging AI capabilities into high-trust, “it just works” product experiences, while raising the quality bar for the broader design organization. You will also help transform the team into AI-enabled designers, setting new standards for how we use AI in our own design process, how we prototype, how we explore, and how we deliver customer value. You will partner closely with Product, Engineering, Research, Marketing, and Design leadership to shape not only what we build, but how we build it. This is a critical role for Dropbox’s AI-first, multi-product future, and for defining the next generation of product experiences that help customers do their best work. Res
