Job Technologien

Deine Rolle im Team

Build and evolve a high-performance, browser-based core application used in real POS and payment environments.
Develop with pure JavaScript - no frameworks, maximum control, full understanding of browser internals.
Work closely with system architects, product managers and a hands-on technical leadership group.
Contribute to an ongoing re-engineering initiative (microservices on Node.js, with Go planned down the line).
Participate in architecture discussions, code reviews and deep-dive technical workshops.
Drive performance, reliability and maintainability across the application.
Grow into architecture or technical leadership if this aligns with your ambitions.
