Description

You'll build Gamma's visual experience: pixel-perfect layouts, smooth animations, and responsive interactions that make the product feel magical. As a Frontend Engineer focused on UI and design systems, you'll partner closely with designers to translate high-fidelity mocks into production-ready, accessible components and build reusable, well-documented component libraries that scale across the product.

Our team has a strong in-office culture and works in person 4–5 days per week in San Francisco. We love working together to stay creative and connected, with flexibility to work from home when focus matters most.

Responsibilities:

  • Own design system components from foundational elements to complex editor UI primitives, with accessibility built in
  • Build pixel-perfect layouts, smooth animations, and responsive interactions across the product
  • Implement polished micro-interactions and transitions that make Gamma feel crafted and intentional
  • Optimize rendering, bundle size, and interaction responsiveness to maintain 60fps animations
  • Solve complex browser challenges including cross-browser compatibility, edge cases, and rendering quirks
  • Partner with designers to translate high-fidelity mocks into production-ready components

Requirements:

  • 3–5+ years of frontend engineering with deep React expertise and mastery of CSS including flexbox, grid, animations, transforms, and browser quirks
  • Sharp eye for detail and craft, with the ability to spot 1px misalignments, janky animations, and inconsistent spacing
  • Experience building complex, interactive UIs such as editors, design tools, or animation-heavy applications
  • Performance optimization skills across React rendering, CSS performance, and animation frame rates, with experience building reusable, accessible, well-documented component libraries
  • Thoughtful approach to user experience including loading states, error handling, and responsive behavior
  • Experience with animation libraries or visual editing tools (Nice to have)

Compensation range: The base salary for this full-time position, which spans multiple internal levels depending on qualifications, ranges between $180K - $275K plus benefits & equity.
