Hi there! Zapier is building the world’s leading AI orchestration platform, where automation and intelligence work hand in hand. As teams and organizations increasingly rely on AI to power their workflows, Zapier is expanding the capabilities, reliability, and adaptability of its platform—so that every automated process can think, act, and evolve alongside the people it supports. We’re hiring UX Engineers to join several high-impact teams across the company. If you’re passionate about bridging design and engineering, crafting delightful, accessible, and high-fidelity experiences, and ensuring our product feels cohesive, intuitive, and expressive, we’d love to hear from you. One of these teams is Builder Copilot, where we’re reimagining how people create automation with the help of AI. Copilot is Zapier’s AI-powered building experience—guiding users from high-level intent to fully configured, production-ready systems. The team works at the intersection of generative AI, complex UI, and real-time feedback, designing experiences that seamlessly shift between conversational guidance and direct manipulation of the product. As a UX Engineer on this team, you’d partner closely with design, product, and engineering to prototype new interaction patterns, push on the boundaries of AI-assisted creation, and help define what intuitive, trustworthy AI tooling looks like in a professional workflow builder. If you thrive on the intersection of design and engineering—turning pixels and prototypes into production-quality, accessible, and maintainable interfaces—this role is for you: • Build experiences used by millions of users worldwide • Champion design fidelity, accessibility, and motion quality across teams • Create interaction patterns that make complex systems feel effortless • Collaborate with cross-functional teams across Product, Design, and Support • Work in a high-ownership environment with visible user impact and fast iteration About You We’re looking for experienced UX Engineers who bring: • Strong experience in React and TypeScript, with deep attention to code quality, maintainability, and performance • Demonstrated ability to translate Figma (or similar) design systems into scalable, production-ready component libraries • A keen eye for visual polish, interaction detail, and animation quality • Fluency in accessibility standards (WCAG, ARIA) and inclusive design principles • Familiarity with design tokens, component theming, and responsive layout systems • Experience designing and implementing UI for complex, stateful workflows or builder-style products • Experience documenting patterns, components, and motion guidelines for shared use • A track record of tight collaboration with Product Designers to maintain high design fidelity • Comfort working in ambiguous, fast-evolving problem spaces where patterns are still being defined • Strong interest in the leading edges of AI-assisted product experiences, including conversational and guided workflows • (Very nice to have) Experience shipping AI-powered features in production, including consideration for trust, failure states, and iteration • (Nice to have) Comfort with lightweight backend integration or prototyping tools (e.g., Next.js, Storybook, or Framer) • Curiosity and craft—someone who obsesses over the small details that make big differences • A mindset of continuous improvement—across tools, process, and personal growth If this role sounds interesting to you, check out the following links for more information about life at Zapier: • <a href="https://zapier
