Full-Stack Developer (Go + TypeScript/React)

What you'll 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 don't toss work over the fence

Our stack

Backend: Go, PostgreSQL, MongoDB, REST/gRPC, Kubernetes Frontend: TypeScript, React, Angular (legacy, being migrated), Electron Tooling: pnpm workspaces (monorepo), Vite, Playwright, Zod/TypeBox Infra: GCP (Polish region), self-hosted Kubernetes, GitHub, Jira/Confluence AI-assisted development: Claude Code is part of our daily workflow

What we expect

• 3+ years of full-stack experience with Go (or a strong backend background in another typed language with willingness to ramp on Go)
• Solid TypeScript + React — you understand hooks, state management, build tooling, and can read Angular code without panic
• Comfort with databases (PostgreSQL and/or MongoDB), API design, and basic Kubernetes/Docker
• Ownership mindset — you take features from idea to production and stand behind them, not just write code and hand it off
• Pragmatic engineering: you ship, you test what matters, you don't over-engineer
• English at working level — written and spoken (this is the cross-team language)

Nice to have

• Experience with Electron, kiosk-mode applications, or any kind of physical-device integration (printers, scanners, payment terminals)
• Czech language — would be great to have for working with local teams and shops, not a blocker
• Monorepo experience (pnpm/yarn workspaces, Nx)
• Domain experience: retail, payments, betting/gaming, or any regulated industry

What we offer

• Real product ownership — your code lands in physical shops, not a feature flag graveyard
• Modern tooling and a team that actually uses AI dev tools well (not as a gimmick)
• Cross-country exposure — colleagues in Prague, Katowice, Zagreb
• Hybrid setup based out of our Karlín office in Prague.
