Staff Software Engineer (Claude Design)

Join Anthropic, a leading AI safety and research company, as a Staff Software Engineer for Claude Design. In this role, you will shape the future of AI-generated design, collaborating closely with research teams and users to create intuitive, high-craft design experiences. You will set the technical direction for frontend problems, run experiments to test product hypotheses, and own the quality bar for the product's look and feel. This is a unique opportunity to work at the intersection of cutting-edge research and real-world application, making a meaningful impact on the future of AI.

• Construire et expédier les surfaces principales de Claude Design, y compris le canevas de conception, l'édition en temps réel, les commentaires en ligne et les contrôles d'ajustement en direct.
• Collaborer étroitement avec les équipes de recherche pour transformer les capacités de vision et de génération de pointe en expériences de conception intuitives et de haute qualité.
• Définir la direction technique pour les problèmes frontend les plus difficiles, y compris l'architecture de l'éditeur et du canevas, la collaboration en temps réel, l'inférence du système de conception, l'import/export riche et la performance.
• Have 8+ years of experience building full-stack applications with deep frontend strength, and a track record of zero-to-one work in startup or startup-like environments
• Work independently with good judgment about what matters, without needing constant direction
• Care about the societal impacts and ethics of your work
• Have strong technical skills across modern web stacks (React, TypeScript, Node.js, Python, Go, etc.), including complex client-side state, performance, APIs, databases, and cloud technologies
• Have set technical direction for a team or workstream and mentored other engineers, while staying hands-on in the code
• Are a generalist who can move comfortably between frontend, backend, and product problems as the work demands
• Communicate effectively and translate complex AI capabilities into intuitive experiences
• Have strong design sensibility and a high bar for craft; you sweat interaction details, motion, and polish
• Are comfortable working in a fast-moving environment where priorities shift and shipping quickly matters
• Hold strong opinions loosely: you advocate forcefully for ideas but change your mind based on evidence
• Are deeply user-centric: you enjoy validating ideas with actual users before over-investing and you talk about problems before solutions
• 100% of the skills listed above
• Experience with real-time, collaborative applications (multiplayer editing, WebSockets) or complex, high-performance frontend interactions
• Direct machine learning or AI research experience
• Hands-on experience with UI/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 (WebGL/shaders, 3D, animation)
• Candidates need not have
• Background conducting user research, interviews, and usability testing
• Extensive experience working with or building visual collaboration & creative tools (e.g., Figma, Canva, Adobe Creative Cloud, etc), and have strong opinions on how they could become more magical experiences
• Formal certifications or education credentials
• Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team
