Frontend Engineer (React)
Build the web side of our platforms in React and TypeScript: trading screens, checkout pages, merchant dashboards and the backoffices our clients run their business from.
About the role
Our platforms are not only apps. Exchanges need fast trading screens, payment gateways need a checkout that converts and a merchant dashboard that makes sense, and every platform comes with a backoffice where our clients manage customers, compliance and money.
You will build these in React and TypeScript, from shared components and modules that each client brands as their own. Real-time data, large tables, complex forms and permission-aware screens are everyday work here.
You will work with our designer on the details and with backend engineers on the APIs, and you will help keep our web module library consistent, accessible and fast.

- Build web apps in React and TypeScript: trading screens, checkout, merchant dashboards and admin backoffices
- Turn designs into accessible, responsive and fast interfaces
- Work with real-time data over WebSockets, large data tables and complex forms
- Maintain our shared component library and its theming for white-label clients
- Write tests, and keep performance and bundle size in check
- Review code and contribute to frontend architecture decisions
