Join Today: Senior Software Engineer - Frontend/React - USA Only
Ready to take the next step in your career? Join us as a Senior Software Engineer - Frontend/react - USA Only! We have an opening at our office in Remote. This position requires a strong and diverse skillset in relevant areas to drive success. An attractive remuneration of a competitive salary is on offer for the successful candidate. Â Â About Us
Close is a bootstrapped, profitable, 100% remote, ~100 person team of thoughtful individuals who value autonomy and impact. WeÂre eager to make a product our customers fall in love with over and over again.
We ?? small scaling businesses. Since 2013, weÂve been building a CRM that focuses on better communication, without the hassle of manual data entry or a complex UI. We are out to supercharge sales productivity with the most modern, thoughtfully all-in-one, AI-powered, and communication-focused CRM.
Our appÂs frontend is a single-page TypeScript web app mostly written in React (originally built with Backbone.js). Our mobile app is built using React Native. We bundle with Vite and target only modern browsers. We test with Vitest, React Testing Library, Playwright, and Chromatic (VRT). Our UI updates in near real-time and is styled via CSS modules and takes advantage of fun technologies like Websockets and WebRTC.
We care about performance (e.g. route-based code splitting or skeleton UI), maintainability, and testability of our frontend code. Our product development process is inspired by Shape Up. We sweat the UI/UX details and work collaboratively with the Product team throughout the design process. This means diving into lo-fi wireframes, and communicating continuously when those ideas are brought to life using Figma and code (Storybook).
Our frontend app is built on top of our REST API & GraphQL endpoints. Our backend tech stack consists of Python/Flask, MongoDB, Postgres, Elasticsearch, and Redis. We run our services in Docker on AWS.
We ?? open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check our projects such as react-custom-scroller, use-infinite-scroll, use-abortable-effect, and smart-tooltip-delay or insights from our day-to-day work on such as Under the Hood: Developing Close's AI-Powered Call Assistant, Cutting our Lead page LCP by half, and Highlights From a Complex Downshift.js Refactor.
