UI Designer / Frontend Developer – Design Systems (m/f/d)

Build and scale a consistent design system by transforming UX concepts and Figma designs into production-ready, reusable components. Integrate AI tools like Cursor and Claude into the design process to optimize development workflows and ensure UI quality.

Responsibilities

• Systematically build and expand our design system - evolve existing approaches with Tailwind CSS and shadcn/ui into a consistent, scalable system that thinks beyond individual components
• Develop reusable UI components with clear APIs, clean documentation, and high quality standards - from buttons to complex data grids
• Transform UX concepts into production-ready components - from Figma designs, but also from Lovable prototypes and Claude Code outputs
• Work closely with the Head of Product Design and Head of Product to ensure the design system reflects and supports the product strategy
• Ensure adoption within the development team - you make sure the design system doesn’t gather dust in documentation but is consistently used in daily code
• Safeguard UI quality through reviews, testing, and systematic consistency checks across all product areas
• Help shape a new design process that natively integrates AI tools like Cursor, Claude, and Lovable - vibe coding is not a buzzword for us but lived practice
• Anchor design system rules in AI-supported workflows - e.g., through skills, prompts, and configurations so that AI-generated code also meets our standards
• Optimize performance, responsiveness, accessibility, and code quality - especially where AI-generated code meets production requirements

Requirements

• 3-6+ years of professional experience in frontend development with demonstrable focus on UI quality
• Strong knowledge of React, TypeScript, modern JavaScript, and Tailwind CSS
• Experience in building and maintaining a design system
• Knowledge of Tailwind CSS and shadcn/ui (or comparable component-based UI libraries like Radix UI, Headless UI)
• Experience developing reusable UI components with clear APIs and clean abstraction
• Proficiency with Figma as a design handoff tool
• Understanding of design tokens and component-based UI architecture
• Experience with modern CSS - Grid, Flexbox, Custom Properties
• Familiarity with AI-supported development tools like Cursor, Claude Code, Lovable, etc.
• Fluent English skills (company language)
• Strong UX/UI understanding and an eye for details, consistency, and visual quality
