New York, New York, United States

Design Engineer

 Job Description:

What you will do

  • Own the design and development of delightful, pixel-perfect, and performant trading interfaces that feel magical to use.
  • Push the boundaries of CSS animations, motion design, and micro-interactions to create interfaces that are both functional and emotionally engaging.
  • Build and maintain a scalable design system (Figma + React + Tailwind) that enables rapid iteration without sacrificing quality.
  • Prototype, experiment, and ship high-fidelity UI/UX that balances creativity with real-time performance requirements.
  • Collaborate closely with product, design, and backend teams to bring new trading workflows from idea prototype production at breakneck speed.
  • Optimize React apps for ultra-low latency, capable of handling hundreds of real-time updates per second without dropping frames.

What you bring

  • 5+ years of frontend engineering experience, with a portfolio showcasing your work (links to live products, Dribbble, GitHub, etc.).
  • Mastery of React, Next.js, TypeScript, and Tailwind (or equivalent modern UI stack).
  • Deep experience with motion libraries like Framer Motion, React Spring, or similar.
  • Proven track record of crafting micro-interactions, animations, and transitions that feel effortless but are engineered with rigor.
  • Strong intuition for visual and interaction design typography, spacing, color, layout, rhythm, and motion all matter to you.
  • Ability to operate as a design engineer: you think in both Figma and code, and can rapidly translate concepts into production-ready systems.
  • High agency, thrive in ambiguous environments, and obsessed with shipping interfaces that delight traders at scale.

Bonus Points

  • Experience building real-time data-intensive applications (finance, trading, or gaming a plus).
  • Have optimised React apps to sustain 60fps under extreme load (hundreds of DOM updates per second).
  • Worked on design systems or component libraries at scale.
  • Contributions to open-source UI/animation libraries.
  • An aesthetic sense that shows up everywhere from thoughtful UI polish to obsessing over easing curves.
