AI coding agents now generate a growing share of the UI our engineers ship, and our design system is the contract that keeps that output on-brand, accessible, and consistent.</p> <p>This role sits at the intersection of design, engineering, and product, with a strong emphasis on craft, usability, and scalability. You'll design and build the system itself, owning interaction decisions and front-end architecture, and translating complex process data and AI-driven behaviors into intuitive, high-performance experiences. It's a senior role: you'll often operate with minimal design oversight, set standards, lead initiatives, and mentor others while staying deeply hands-on in both design and code.</p> <p><strong>About the team</strong></p> <p>You'll join the team that owns Celonis's design system and the operations behind how design gets done. We sit at the intersection of design and engineering, and we treat the system as a living product with real users, internal designers, product engineers, and the AI agents that now consume it.</p> <p><strong>What you'll do</strong></p> <ul> <li>Design and build production components in Angular and TypeScript, our design system is built in Angular and we may adopt React over time, on a foundation of rock-solid HTML and CSS (semantic markup, ARIA, and modern CSS custom properties driving design tokens).</li> <li>Own interaction decisions, component design, and front-end architecture end-to-end, independently translating ambiguous requirements into thoughtful, usable UX.</li> <li>Translate complex process-intelligence data and AI-driven behaviors into clear, intuitive, high-performance operator experiences.</li> <li>Set the technical and craft standard for front-end quality, polish, motion and animation, performance
