Member of Technical Staff (Software Engineer, Design System)

About the role

Perplexity is looking for a frontend engineer to build the design system behind every Perplexity product. It is the component library and design language shared across web, iOS, Android, macOS, and Windows – the primitives, tokens, and interaction patterns that every product team builds on top of. Its users are internal, spanning product teams and a broad range of contributors across the company. The components you build become the foundation all of them rely on.

Responsibilities

• Design and build core primitives – overlays, inputs, navigation, feedback – with APIs that stay coherent as consumers multiply
• Work across the design-token pipeline – authoring, generation, and per-platform publishing across web, iOS, Android, macOS, and Windows
• Partner directly with design on the design language itself, translating Figma systems into typed, testable, documented components
• Migrate product surfaces off 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 docs, visual regression coverage, and on-call rotation

Requirements

• 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 TypeScript, and CSS
• Working accessibility knowledge (WCAG, ARIA patterns, assistive tech)
• Comfort collaborating closely with designers on the visual and interaction language

Skills

• React
• TypeScript
• CSS
• Design Tokens
