What does our teams do

We build the software backbone for a multi-country retail betting operation across Czech Republic Poland and Croatia. Our products are touched by thousands of end-users daily: self-service betting terminals (SSBT) cashier POS terminals (Kasa) and the Backoffice system that ties it all together. Were a cross-country engineering organization with active migrations modernizing our entire retail stack Angular React for Self Kiosk PyQT Electron for the POS Terminal.

What you will work on:

• Feature development across our retail monorepo Go services on the backend TypeScript/React (and remaining Angular) on the frontend
• One of our flagship products: United SSBT (self-service terminals) United POS / Kasa (cashier app) Retail Backoffice or the Self Kiosk migration
• Integrations with payment systems thermal printers (ESC/POS CUPS) scanners and other retail peripherals
• Shared TypeScript packages used across Self Kiosk and POS Terminal
• Port/adapter architecture for per-market (CZ/PL/HR) business logic
• Real production code that runs on real hardware in real betting shops fast feedback real impact
• Strong ownership of delivered features you own what you ship from spec through production: design decisions code quality rollout monitoring and post-release fixes. We dont toss work over the fence
