San Francisco, CA Hybrid Employment

Prosper is hiring a Sr. UX Designer

Responsibilities

  • Lead end-to-end UX design for authentication, payments, and other core platform services, from initial discovery through delivery
  • Partner with researchers by providing prototypes, design thinking, and artifact support that enable effective research across the platform
  • Serve as a thought partner to product managers, engineers, and security stakeholders, shaping how problems are framed before solutions are proposed
  • Develop and maintain clear, thorough design documentation that supports async decision-making, legal review, and cross-team alignment
  • Navigate legal and compliance approval workflows for features that intersect with financial regulation, security requirements, or data handling
  • Define the design direction for Foundations features, including universal login and payment flows, and maintain the systems-level patterns that those features depend on
  • Collaborate with engineers through implementation, reviewing production output against design intent, and flagging fidelity issues early
  • Use AI-assisted tools, including Cursor and Figma MCP (Model Context Protocol), to reduce repetitive tasks and keep design-to-code workflows efficient
  • Contribute to cross-team UX initiatives, including component infrastructure work, that extend beyond Foundations
  • Mentor UX team members on AI-assisted workflows and research-to-design best practices

Requirements

  • 8-10+ years of product design experience focusing on design systems, platform UX, or component libraries (or equivalent combination of education and experience)
  • Deep fluency with Figma, including prototyping, auto-layout, component architecture, and design token management
  • Hands-on experience in AI-assisted development environments such as Cursor, GitHub Copilot, or similar tools
  • Systems-oriented design approach: a track record of designing for scale, reuse, and consistency across multiple products or surfaces
  • Clear communication in cross-functional settings, with the ability to work effectively alongside engineering, product, and security stakeholders
  • Confidence operating in a fintech or similarly regulated product environment

Nice to Have

  • Experience with Figma MCP or other design-to-code pipeline tooling
  • Front-end fluency sufficient to read and discuss React-based code alongside engineers
  • Background in accessibility standards applicable to financial products
  • Prior work on internal tooling or developer-facing design surfaces
