• Assumer la responsabilité de la mise en œuvre de l'interface utilisateur pour de nouvelles fonctionnalités, en collaborant étroitement avec les chefs de produit, les designers et les ingénieurs.
• Posséder et faire évoluer le système de conception de l'entreprise, en définissant et en maintenant les API des composants, les modèles de composition, les normes d'interaction et la documentation.
• Identifier et réduire systématiquement la dette UI et UX, améliorer les modèles de mise en œuvre et élever le niveau d'artisanat global de l'application.

• You have genuine curiosity about AI tooling and a grounded enough understanding of how these tools work to build with them
• You can identify what's wrong (or right) with a design or component, articulate the specific reason why, and know how it could be improved
• You're well-versed in React, JavaScript (TypeScript), HTML, and modern CSS
• You have strong opinions about craft, you hold yourself to a high bar, and your portfolio or GitHub shows it. You sweat the details and truly care about the last 10% that makes great software
• You work in a real engineering environment. You’re comfortable using Git, writing PRs, reviewing code, and contributing directly to a shared codebase
• You prioritize speed, reusability, accessibility, cross-browser support, functional motion as you build, not as an afterthought
• You own your work: You take pride in your work, follow through on commitments, and feel a deep sense of responsibility for outcomes, not just tasks
• You’re energized by complexity and ambiguity: You enjoy tackling problems that don’t come with a playbook. You’re comfortable building from scratch, iterating as you go, and collaborating to shape the best path forward
• You build with AI, not just use it: You're actively embedding AI into how you work, pushing what's possible, and bringing your team along with you
• You care about impact, not noise: You care deeply about the substance of your work. You measure success by results, not recognition, and you let your work speak for itself
• You seek out feedback: You see directness as respect, not criticism. You actively seek input, sit with hard truths, and use feedback as fuel for improvement
• You crave autonomy: We trust our team with big challenges and the freedom to solve them. If you’re someone who takes initiative, is comfortable taking risks, and seeks input when needed, you’ll find the freedom here empowering
• You push relentlessly for reinvention: You're always asking "how can this be better?" -- in your work, in your craft, in yourself. Comfort is a signal to push harder, not coast. You'd rather build something better than defend something familiar
• You're encouraged to apply even if your experience doesn't perfectly match the job description -- your perspective and drive matter more
• You've owned or made meaningful contributions to a React component design system (components in code, not just Figma libraries)
• You have experience with motion or animation work (motion/react, GSAP, or vanilla CSS animations)
