Bryntum is a small and charming tech company rooted in Stockholm (and registered in Lund), founded in 2009. They focus on building high-performance, modern JavaScript and TypeScript components - such as Gantt, Scheduler, Calendar, Grid and Kanban - that integrate into React, Angular, Vue or plain JavaScript apps. The components are used by over 5,000 companies in more than 80 countries - from tech giants to well-known universities.

Their tools are more than pretty diagrams - they include features like dependency handling, real-time scheduling, resource management, themes and export options (PDF, Excel, PNG and more). All this supports large datasets while maintaining smooth performance thanks to well-tested APIs and thin, packaged components.

The work culture is genuine and warm - the team (25+ people) is based in Stockholm and enjoys fika as much as code. They also use tools like Siesta for testing and host a helpful support forum culture, making them an ideal choice for developers who value technical excellence and a personal approach.
