About the role
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.
