About this role

Design Engineer San Francisco | OnSite ABOUT THE ROLE You'll own the design and development of Sim's visual, agent-building platform-the canvas where developers build, connect, and launch AI agents. From architecture to polished interactions, you'll define how thousands of developers visually create with Sim. Your work blends UI/UX design with engineering, shaping the interface, experience, and real-time systems at the heart of our product. Sim has been called "Figma for AI agents," and you'll push this further-making our canvas more powerful, delightful, and performant as workflows grow. You'll partner with engineering, design, and product to deliver a seamless agent-building journey from initial creation through to production. This is a foundational role. You'll set standards across visual design, interaction patterns, and UI responsiveness. On our lean team, you'll influence everything the user interacts with and rapidly ship features that impact thousands. What You'll Do - Own the design and development of Sim's visual canvas-the real-time, drag-and-drop editor central to our platform - Architect and implement intuitive UI systems for complex agentic workflows - Shape how developers interact: design, test, debug, and deploy agents seamlessly within the product - Ensure the experience remains fast, beautiful, and robust as workflows grow in size and sophistication - Bridge visuals and execution: what users see is what runs - Set standards for front-end code, component architecture, design systems, and user ergonomics - Collaborate across the stack in our Next.js monorepo; ship to production daily - Define and refine UX/UI patterns, with attention to developer delight
