We're looking for a Senior Front End Engineer with deep expertise in Next.js to join our fast-paced, high-impact engineering team. You'll work directly with our co-founder and CTO, an AI startup veteran with a successful exit, a decade of ML experience, and a Forbes 30 Under 30 recognition.

• Experiment with AI-driven front-end experiences, such as agent-driven interfaces and real-time collaboration.
• Contribute to design systems and front-end architecture best practices, raising the bar for engineering excellence.

What We're Looking For

• 4+ years of professional experience in front-end development, with strong proficiency in React, Next.js, and TypeScript.
• Deep understanding of SSR/SSG, API integration, and performance optimization in Next.js.
• Experience with state management libraries (Redux, Zustand, or similar).
• Familiarity with frontend tooling (Webpack, Vite, Babel) and testing frameworks (Jest, Cypress, React Testing Library).
• Ability to thrive in an ultra-fast-paced startup environment where we ship daily.
• Strong product sense and design intuition; experience working closely with designers.
• Bonus points for experience with:
  • AI-driven interfaces or conversational UI patterns
  • TailwindCSS, Storybook, or building component libraries
  • Sales/GTM tools or enterprise SaaS platforms

Why Join Us

• Y Combinator-backed. Join a venture-backed company with high-growth potential and massive market opportunity.
• Competitive compensation. Mix of stock plus cash - we want you to share in the upside of what we're building.
