The Role
We’re looking for a Senior Front End Engineer with deep expertise in Next.js to join our fast-paced, high-impact engineering team.

- Implement scalable and reusable UI components, ensuring strong accessibility, responsiveness, and cross-browser compatibility.
- Optimize performance (server-side rendering, caching, dynamic imports, etc.) to deliver lightning-fast user interfaces.
- 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
- Work with world-class founders. Get direct mentorship from elite technical leaders and play a critical role in shaping a category-defining company.
- Extreme impact. Your code will define the look and feel of the product that customers interact with every day.
- Remote-first. Work from anywhere with WiFi while collaborating with an all-star team.
- 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.
