Senior Full Stack Engineer

About the Role

Paperpile uses React and TypeScript across all product lines: web app, browser extensions, iOS and Android apps (React Native), and desktop apps (Electron). You'll take ownership of substantial parts of our codebase, shipping polished UI and the connected backend services for new features and products.

You’ll write and maintain frontend (Playwright) and backend tests, and help keep our CI/CD pipelines healthy.

• Deep understanding of React and a track record of building complex, production React applications.
• Able to deliver pixel-perfect, production-ready code from Figma mockups on time.
• Strong knowledge of TypeScript and its ecosystem (Babel, Webpack, Jest, Express) and underlying web technologies (HTML5, CSS3, REST APIs).
• Solid backend skills in Node.js: comfortable building and consuming APIs, implementing algorithms, and data heavy processing workflows.
• Experience running production backend services reliable and efficiently at scale.
• Experience writing complete, robust and maintainable tests with Playwright or similar frameworks.

Additional useful experience includes React Native, browser extension development, Electron, web crawling, PDF processing, and AWS server operations.
