About Close

Close is the CRM with a built-in AI teammate that works with your team to call leads, qualify prospects, book meetings, and keep your CRM up to date automatically, so you can focus on selling. Backed by Y Combinator.

About the role

When you apply, you’ll have an opportunity to highlight the team that appeals to you the most. We’ll do our best to honor this preference, but we'll also be evaluating skillset fit and the needs of the business. One thing to know up front: we do move people between teams as the work shifts.

Our frontend is a single-page TypeScript web app built in React. We bundle with Vite and target modern browsers only. We test with Vitest, React Testing Library, Playwright, and Chromatic for visual regression. Our UI updates in near real-time using WebSockets and WebRTC, is styled via CSS modules, and is performance-tuned with route-based code splitting and skeleton UI. We've built our own design system, documented in an extensive Storybook.

We sweat the UI/UX details and work collaboratively with Product throughout the design process - from lo-fi wireframes through Figma and into code. Our frontend...
