Front End Engineer

Technology

Our product sits on top of many modern technologies, including a TypeScript/Node.js backend with Express, MongoDB for database storage, React for web applications, and Flutter for mobile platforms. We pride ourselves on leveraging AI wherever possible to speed up internal workflows.

The Job
