About the role
You'll build Gamma's visual experience: pixel-perfect layouts, smooth animations, and responsive interactions that make the product feel magical. That means owning design system components from buttons and inputs to complex editor UI primitives, implementing polished micro-interactions and transitions, and solving tough browser challenges across compatibility and rendering. You'll sweat the details (spacing, typography, hover states, loading states, error states, edge cases) while keeping frontend performance sharp.
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. This role requires mastery of CSS, a sharp eye for craft, and an instinct for when to polish versus when to iterate.

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
What you'll bring
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
