We're looking for a Senior Frontend Engineer to own and evolve our design system - not just consume it. You'll turn Figma designs into reusable, accessible React + TypeScript components and drive their adoption across product teams.

Responsibilities:

• Build and maintain our component library (React + TypeScript): tokens, layout primitives, complex components.
• Translate Figma designs into accessible, responsive, production-ready components.
• Document components and usage guidelines in Storybook.
• Own versioning/publishing of the library as an internal npm package.
• Drive adoption across squads and prevent UI drift/duplication.
• Ensure accessibility (WCAG/ARIA) and cross-browser consistency.

• Mentor other frontend engineers on the design system.

   

Requirements:

• 5+ years frontend experience, strong React + TypeScript
• Proven experience building or scaling a design system/component library — not just using one.
• Strong grasp of component API design and reusable styling (CSS-in-JS, Tailwind, or similar).
• Experience with Storybook and accessibility standards (WCAG 2.1+).
• Experience versioning/publishing internal npm packages.
• Comfortable working directly from Figma, including design tokens.
• AI-first workflow: regularly delegates real, multi-step tasks to AI coding agents (Copilot, Claude Code, Cursor, or similar) — provides proper context, reviews diffs critically, verifies output, and has a clear process for when the AI gets it wrong.

• Bonus: AI-native, not just AI-using — creates or customizes skills/MCP servers, manages context deliberately, picks the right model for the task, and can speak to specific failures and trade-offs (not just tool/brand names).

   

Nice to Have:

• Design tokens tooling (Style Dictionary).
• Prior experience as a design system owner/lead.

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
• Education reimbursement
• Memorable anniversary presents
• Corporate events and team buildings

• Other location-specific benefits
