About the Role: Hiring a Staff AI Frontend Engineer who sits at the intersection of product design and frontend engineering. You are an engineer first, but with exceptional design sensibility that elevates everything you build. You will define and implement the look and feel of AI-native workflows, ensuring complex enterprise tools feel as intuitive as the best consumer apps. The product includes a real-time WebRTC-powered companion agent that follows users across their screens, generative dashboards that visualize complex enterprise context graphs, agentic chat that operates the web application directly, and a fundamentally new UI paradigm built around generative AI. You will ship at AI speeds, work directly with a tight founding team, and help define the future of the frontend SDLC.

What You'll Own

• Architect scalable frontend systems: design reusable component libraries, establish patterns for state management and API integration, optimize bundle sizes, ensure the platform performs beautifully at scale
• Own and ship the primary user-facing features users interact with daily, end-to-end from React components through API integration to production polish
• Bridge AI capabilities with elegant user experiences: partner with product and backend engineers to expose powerful functionality while hiding technical complexity
• Build complex frontend systems, including real-time WebRTC streaming for the companion agent, generative dashboards, and agentic chat that operates the product itself
• Use AI tools to rapidly prototype design concepts in code, bridging gaps between teams with working demos instead of static mocks
• Help define how the team scales code review and SDLC with agents that encode your architectural thinking

Requirements Must-Have

1. 6+ years shipping production-grade products. Senior to Staff level.
2. Mastery of modern web technologies: React, Next.js, TypeScript, Tailwind. You understand the performance consequences of architectural decisions and ship code that's elegant and performant.
3. AI-native developer. You wield Cursor, Claude Code, v0.dev, Lovable, and comparable tools as extensions of your craft. You ship multiple features per day with AI assistance.
4. Engineer first, designer by instinct. You discuss Server vs Client Components as fluently as you critique spacing and visual hierarchy.
5. High agency. You've pushed yourself outside structured environments as a founder, founding engineer, or with significant scope ownership at a real startup.
6. On the bleeding edge of AI tooling. You can articulate what changed in your stack in the last three months.
7. Comfortable talking to customers and sales. You shape product through action, not waiting for permission.
8. Based in SF or willing to relocate immediately. In-person 5 days a week downtown SF.

Nice-to-Have

• Prior founder or founding engineer experience
• Real-time WebRTC streaming or video pipeline experience
• Voice AI product experience
• Generative UI or generative dashboard work
• Python backend comfort for occasional cross-stack work
• No CS or Engineering degree required; portfolio, GitHub, and shipping track record matter more
