Who we are

We are Rounded Square. We're not a typical agency. We're an engineering boutique, created by engineers for engineers. We operate like a startup in the shape of an agency. That means we keep the speed and innovation of a startup, but with the project diversity of an agency. We're not looking for 'inventory' to warm a chair. We're looking for people who — like us — enjoy building cool shit and solving complex problems without beating around the bush.

What you'll do

You build complete solutions, not just 'lipstick'. We choose technology based on the problem, not the other way around. Currently we work most with:

Backend: .NET, Spring Boot
Frontend: Next.js (SSR, modern standards)
Mobile: Flutter

The tech stack isn't set in stone. What if you don't know everything? Maybe you're at home in .NET, but Flutter is new? Or you've mastered Java (Spring), but need a refresh on React? No problem. We're looking for an engineering mindset, not an encyclopedia. In 2026, a good engineer (with our mentoring and AI tools) learns a new language in one weekend — at least enough to be productive on Monday.

What we're looking for

Backend Logic

You understand databases, APIs, security, and architecture.

Agility

You get a problem -> you research (docs/AI) -> you solve the problem.

Independence

You know agile concepts, especially taking ownership of a task, while understanding that SCRUM isn't the bible.

Compensation & Growth

Compensation is flexible and depends on your experience and output. If you prove yourself, the number goes up fast — we reward growth directly.

What else you get

Equipment & Tools

We pay for all AI tools and software that makes you faster.

Mentorship

You work directly with a team of seniors and founders.

Flexibility

Maribor office or Remote. Contractor or employment. What matters is that the work gets done.

How to apply

No long cover letters. Send us your GitHub/Portfolio and a short description of a situation where you had to learn something completely new in a very short time (and you succeeded).
