  • Design and ship readable, performant data visualizations such as time series, breakdowns, combo charts, and KPI strips.
  • Craft AI and agent user experiences, including streaming traces, multi-step progress states, follow-up conversations, and rich result artifacts.
  • Own and extend the design system, including design tokens, reusable components, motion, animation, and accessibility.
  • Prototype mock-first solutions for rapid product iteration and then harden proven flows with real data and APIs.
  • Ensure frontend performance and correctness, including React rendering behavior, SSR and hydration, bundle size, and edge-case bugs.
  • Build and consume REST and JSON APIs, wire backend services or BFF endpoints, shape data contracts, and integrate LLM or agent backends.
  • Maintain a healthy codebase that is typed, linted, documented, and easy for others to pick up.
  • Collaborate closely with product and design to shape the user experience and move quickly from idea to shippable flow.

Requirements

  • Experience with a modern React framework such as Next.js, including App Router, SSR/CSR trade-offs, data fetching, and routing.

  • Experience with data visualization or charting and making dense information legible.
  • Strong product judgment and comfort making independent UX decisions, including states, empty/loading/error handling, motion, and micro-interactions.
  • Comfort with Git, code review, and iterative shipping.
  • Ability to stand up and consume APIs using Node/Express or Python/FastAPI, with understanding of request/response shapes, auth, and async behavior.
  • Comfort integrating LLM or agent APIs, including streaming responses and tool/function calls.
  • Nice to have: experience with AI-native UX such as copilots, RAG/agent interfaces, streaming token-by-token UIs, or reasoning patterns.
  • Nice to have: experience building or maintaining a design system or component library.
  • Nice to have: fintech or payments domain exposure, including acceptance rates, routing, fraud, or PSPs.
  • Nice to have: animation or motion experience such as Framer Motion, CSS transitions, or micro-interactions.
