ABOUT PRODUCTIVE

Productive’s aim is to provide agencies with a complete and real-time overview of their business.

WHO WE ARE LOOKING FOR

Are you a computer science student eager to gain hands-on experience in software engineering? Do you want to work on real-world features that thousands of users rely on every day?

At Productive, we’re opening aSoftware Engineer Internship where you’ll join one of our product teams and work on either the Frontend or the Backend, depending on your interests and strengths.

You’ll collaborate with experienced engineers, participate in real development cycles, and get exposure to everything from design discussions to deployment.

And yes, it’s more than just writing code. You’ll join team meetings, learning sessions, and (of course) team social events.

WHAT YOU’LL WORK WITH

We primarily useEmber.js and TypeScript on the frontend, andRuby on Rails, MySQL, and Redis on the backend, so you’ll have the opportunity to learn modern web technologies and apply them to real-world scenarios. Depending on your interests and strengths, you’ll join either our Frontend or Backend track.

AI is a core part of how we work at Productive - not a buzzword, but a daily tool. Our engineers use AI tools for coding assistance, writing specifications, and reviewing pull requests. We're also actively building AI-powered features into the product itself, with a growingroadmap that means you'll be working on and alongside AI from day one.

You’ll have adedicated mentor within one of our product teams who will guide you through real development workflows, from planning and implementation to testing and deployment.

This paid internship is based in ourZagreb office and will last three months, starting at the end of April 2026. If you're interested, we will discuss afull-time job offer after the internship.
