Sr. UX Designer
Summary
Senior UX Designer at Prosper Funding designs universal login and payment flows for their fintech platform, collaborating closely with engineers in React/Figma and AI tools like Cursor to build consistent, secure systems across products.
Your role in our mission
This position sits at the intersection of product design, technical platform work, and systems thinking. The Senior UX Designer on Foundations shapes the systems that ensure a consistent, secure, and accessible experience regardless of which product a customer is using. The work ranges from defining universal login patterns to designing unified payment flows, and it requires a designer who is as comfortable in an engineering conversation as in a design critique.
The engineering team works in React-based frameworks and uses Figma alongside AI-assisted tooling, including Cursor and Figma MCP (Model Context Protocol). This role is not a handoff-oriented role. The expectation is active collaboration with engineering through implementation, supporting engineers in translating design decisions into production-quality work and catching fidelity issues before they compound.

The team you’ll thrive with
The Foundations team owns the core services that much of Prosper's fintech portfolio depends on, including authentication and payments. Because this work sits at the platform level, design decisions here often have reach across multiple products and teams. This role also contributes to UX initiatives outside the Foundations team, including component infrastructure work that spans the broader product organization.
