About the role

What You'll Work on

  • Own the craft and interaction quality of the product end to end, holding the line on detail and polish in a domain (fund accounting, treasury operations) that is inherently dense and complex
  • Design and build the interaction patterns for workflows where humans and AI agents work side by side, including how a person reviews, corrects, and builds trust in agent-driven output in real time
  • Own our design system and the tooling around it: components, patterns, documentation, and the best practices other engineers use to build consistent, high-quality UI
  • Prototype rapidly in code rather than static mocks, using working software to test ideas with users and stakeholders
  • Make the final call on product taste and interaction design in the areas you own, and build the judgment and context to be trusted with that call
  • Partner with product, ops, and engineering to translate genuinely complex financial workflows into interfaces that feel simple and obvious in the hands of the person using them
  • Work directly with customers and internal ops teams to see how workflows actually happen, and use that context to shape design decisions
  • Balance speed and quality as a company still defining its product surface area, knowing when to move fast and when to slow down for the right long-term foundation

Requirements

  • Currently hands-on, shipping user-facing product code today, not managing, reviewing, or architecting from a distance
  • Exceptional taste: shipped work where the interaction design and craft are the reason it stands out, not just the functionality
  • Strong full-stack fluency, comfortable owning a feature from database to UI, with particular strength on the frontend
  • Experience with genuinely complex UI/UX: dense data, multi-step workflows, real edge cases, not just clean greenfield consumer surfaces

Nice-to-Haves

  • Experience designing for AI agent or automation-heavy products, especially human-in-the-loop review flows
  • Background in fintech, capital markets, or other data-dense B2B software
  • Experience building, owning, or significantly leveling up a design system, not just consuming one someone else built

Stack

  • TypeScript/React
  • Figma to code workflows (v0 or similar)
  • Internal component library
