Senior QA Engineer (USA Only - 100% Remote)

Our app’s frontend is a single-page TypeScript web app mostly written in React. Our mobile app is built using React Native. Our UI updates in near real-time and takes advantage of fun technologies like Websockets, WebRTC, and GraphQL Subscriptions. Our backend tech stack consists of Python/Flask, MongoDB, Postgres, Elasticsearch, and Redis, and communicates with clients via our REST API & GraphQL endpoints. We run our services in Docker on AWS.

We care about performance, maintainability, and testability of our code. We test with Vitest, React Testing Library, Playwright, and Chromatic (VRT). Writing tests is embedded into our engineering culture. We also house lists of manual test steps to follow for testing critical features like calling and composing emails. Our focus is on testing actual user behaviour, leveraging the Testing Library approach.

We sweat the UI/UX details and work collaboratively within cross-functional product development teams. We think about testing in the technical specification phase and we continuously spend time assuring we’re shipping a high-quality product.

We love open sourcing our code and ideas on our GitHub and on The Making of Close, our behind-the-scenes Product & Engineering blog. Check out our projects like TaskTiger and use-infinite-scroll or insights from our day-to-day work on such as Rendering untrusted HTML email, safely, How We Improved Reliability Of Our WebSocket Connections, and Cutting our Lead page LCP by half.
