About the role

Founding Design Engineer role at Finta, a YC-backed startup, focusing on building and evolving the design system, delivering production UI, and shaping product craft at the intersection of design and engineering. Founding role with ownership over product direction and design engineering function.

Responsibilities

  • Build and evolve Finta’s design system: the components, tokens, patterns, and motion language that everything is built on
  • Ship polished, production-ready UI across product, marketing, and our website
  • Create reusable building blocks like data tables, filters, navigation, loading states, animations, and interactive patterns
  • Bring modern interaction design to a Rails codebase with fluid transitions, micro-interactions, and the kind of craft you see in tools like Linear, Cursor, and Vercel
  • Explore what’s possible at the edge of UI in the age of AI: streaming interfaces, agent status patterns, real-time feedback, and new interaction paradigms
  • Work directly with the CEO and engineering team to shape what we build and how it feels
  • Set the quality bar for every pixel that ships
  • Influence product direction, not just execution. You’ll have a voice in what we build, not just how it looks.

Qualifications

  • Have deep expertise in HTML, CSS, and JavaScript. You think in the browser, not in abstractions.
  • Have production experience with server-rendered stacks: Rails, Hotwire, Turbo, Stimulus, Tailwind, ViewComponent, or similar
  • Obsess over details like animation timing, easing curves, hover states, spacing, and color. The things most people don’t notice but everyone feels.
  • Use AI tools daily to move faster (Cursor, Claude, Conductor, or similar) and can show real examples of shipping with them
  • Have a strong visual eye and design sensibility, even if your title has always been “engineer”
  • Can point to work you’ve shipped that made people say “damn, this feels good”
  • Ship fast and iterate. You’d rather put something real in front of users than polish a mockup.
  • Are excited about being early. You want to define the standard, not follow one.
