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 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.

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.
