Member of Technical Staff; Software Engineer, Design System) San Francisco, Perplexity Design tokens

Perplexity is hiring a frontend engineer to build the design system used across Perplexity products, the component library and design language shared across web, iOS, Android, macOS, and Windows. The role focuses on developing component APIs for internal product teams, contributing to the token pipeline that keeps platforms visually consistent, and maintaining interaction quality and accessibility. The listed tech stack is React, Type Script, CSS, and design tokens.

• Design and build core primitives (overlays, inputs, navigation, feedback) with APIs that remain coherent as consumers multiply
• Work across the design-token pipeline including authoring, generation, and per-platform publishing across web, iOS, Android, macOS, and Windows
• Partner directly with design to translate Figma systems into typed, testable, documented components
• Migrate product surfaces from bespoke implementations onto shared primitives without breaking them
• Build accessible components by default (keyboard, focus, contrast, screen readers) backed by automated coverage
• Support consuming teams through documentation, visual regression coverage, and an on-call rotation

• 4+ years building production frontend; experience with a design system, component library, or shared UI platform is a plus
• Interest in building reusable components
• Strong React and Type Script, and CSS
• Working accessibility knowledge (WCAG, ARIA patterns, assistive tech)
• Comfort collaborating closely with designers on the visual and interaction language
