About the role

We're rewriting the established admin solution of a large multi-tenant e-commerce platform in modern React. This isn't a greenfield build into thin air – it's a real refactoring effort with a clear goal, an existing business behind it, and room to set up the architecture the way it should be. If you enjoy building clean, reusable components and want to use AI tools to their full potential, not just as an afterthought, come join us.

What Will Be Your Job

  • Refactoring and rewriting the existing admin interface in React

  • Developing and implementing scalable, reusable components

  • Integrating the frontend into a PHP monorepo via Inertia.js and TanStack React Query

  • Building and maintaining admin web applications for a multi-tenant platform

  • Code review, technical discussions, and collaborating on the frontend architecture

  • Actively using AI tools directly in development

What makes this role special?

  • Real impact: refactoring a platform that clients actually use, not a practice project

  • AI, daily: AI tools here aren't a nice-to-have, they're a normal part of the job

  • Freedom: full remote, or a share desk at the ARTIN office in Brno or Prague

  • Flexibility: freelance collaboration (trade license), start ASAP

who we´re looking for

  • A developer with proven commercial experience in React and TypeScript

  • Experience with Inertia.js, TanStack React Query, and frontend testing

  • You care about code quality and consistent code style – ESLint and Prettier make sense to you

  • You actively use AI tools in development and want to keep pushing further with them

TECH STACK YOU'LL WORK WITH

  • Frontend: React, TypeScript, Inertia.js, TanStack React Query

  • Backend: PHP monorepo

  • Tools: ESLint, Prettier, frontend application testing

  • AI tools as a standard part of the workflow

What Your Future Colleagues Say about ARTIN

I'm constantly switching between different projects, learning new technologies, and facing fresh challenges. That's what keeps my developer brain happy. I’d get bored doing the same thing over and over.

JAROSLAV MÜLLER
Senior Developer & Solution Architect

We have a refreshing approach to work culture. There's no status-chasing or bureaucratic red tape to cut through. Need a software license? No endless approval chains—just a simple conversation. Want to try a new way of doing things? We'll find a way that works for both sides.
