Staff+ Software Engineer, Claude Design

About the role

Claude Design lets anyone collaborate with Claude to create polished visual work: interactive prototypes, product mockups, slides, and animations. We're making Claude the best visual storyteller there is, lowering the floor so anyone can bring an idea to life, and raising the ceiling on what the most skilled creators can make. We work on Artifacts in Claude, and so far we've shipped new kinds of artifacts like Claude Design, Slides, and Motion, and we are exploring new bets.

We're looking for Software Engineers to help build and shape Claude Design and the creative capabilities of Claude. This is a craft-heavy, product engineering role: you'll create the canvas, real-time editing, design-system inference, and AI-driven generation experiences that make AI-generated design feel like a tool people reach for first, not a demo. You'll work at the intersection of cutting-edge research and real-world application, rapidly building and testing new experiences, partnering directly with researchers and users, and helping to generate the crucial insights that shape where the product goes next. You'll join a small, fast-moving team with high autonomy.

Key responsibilities

• Build and ship user-facing features across our products, and help decide which creative spaces we explore next
• Set technical direction for these products, including editor and canvas architecture, real-time collaboration, and rich import and export
• Own the quality bar for how these products look and feel, treating latency, responsiveness, and reliability as first-class concerns and raising user experience and design considerations early
• Partner with researchers to rapidly prototype experiences around vision and generation capabilities, and help improve the quality of what Claude generates
• Spend time with users and dig into how people actually use what you ship, then turn what you learn into what we build next
• Build the shared foundations that let us launch new creative tools quickly and make them work well together

Minimum qualifications

• Strong design sensibility and a high bar for craft, including attention to interaction details, motion, and polish
• Strong full-stack engineering skills, including production frontend and backend work on user-facing web products
• Ability to thrive in ambiguity and be energized by uncertainty
• High agency, good judgment about what matters, and a bias toward shipping
• A deeply user-centric approach: you validate ideas with actual users before over-investing and talk about problems before solutions
• Strong opinions held loosely: you advocate forcefully for ideas but change your mind based on evidence
• Care for Anthropic's mission and the societal impacts of your work

Preferred qualifications

• Extensive experience working with or building visual collaboration and creative tools
• Experience with UI and UX for AI-powered applications, and fluency collaborating closely with designers
• Deep frontend expertise in canvas rendering, complex editor UIs, design-system tooling, or graphics work, such as WebGL, shaders, 3D, or animation
• Experience with real-time, collaborative applications, such as multiplayer editing and WebSockets
• Background conducting user research, interviews, and usability testing
• Experience building and shipping products from 0 to 1
• Experience building product platforms, primitives, or shared foundations that other products and teams build on top of
• Performance optimization experience, such as profiling, improving rendering, and tracing end-to-end latency
