WHO WE ARE LOOKING FOR

A student passionate about all things web, eager to gain hands-on experience in the tech industry.

Are you a student of computer science or a related field? Join our internship program and learn from the best! You’ll be part of our JavaScript team working on diverse web and mobile projects for clients around the globe.

You’ll work alongside experienced engineers, designers, software testers, and project managers, and under the guidance of a mentor. Our go-to technologies are React and Angular, but some team members also work with Vue, Node.js, and React Native. You’ll learn about the project lifecycle from concept to delivery, and find out first-hand how we handle client interactions.

Our JavaScript team consists of 25 engineers well-versed in all things web. We mainly work on solutions that run in browsers, but we can handle backend and mobile requests when the project calls for it. Some of the projects we’ve worked on include a corporate website for a finance company, a trading platform, an online conference platform used by the scientific community, a leasing solution for a regional bank, a suite of apps for cruise line photography, and an interactive map for truck drivers and operators. Continuous learning is part of our culture. The team hosts weekly lectures and workshops, and actively contributes to the open-source community. You’ll have plenty of opportunities to get involved and sharpen your skills.

This paid internship is held on-site in Zagreb.

Tools
we use

Next.js

We choose Next.js as a React framework for our applications.

Docker

We rely on Docker for simplifying the packaging and running our applications in production

Jest

Ever since we introduced Jest, testing has gotten easier, and now we try our best to use it wherever it makes sense.

GitHub Actions

We use GitHub Actions to build, test, and deploy our client code.

GitHub

All of our work is on Github. Everything goes through pull requests and code reviews with your future team members.

ESLint

Working with other people is so much easier with a mature style guide. We use ESLint to help us enforce a consistent code style.

Prettier

A tool in our tool belt that helps us save time both on formatting discussions and actual formatting.

Tailwind

We rely on Tailwind CSS because it lets us move quickly from idea to polished UI without fighting custom CSS, keeping our design system consistent and our workflow efficient.

Angular CLI

We make use of everything that comes with Angular CLI for easier configuration, code generation, organization, and building.

Jasmine

Writing unit tests is a crucial part of our development cycle and Jasmine is a great out-of-the-box solution.

ESLint and stylelint

Having multiple people work on a project can be challenging if there is no style guide defined. ESLint and stylelint help us adhere to our style guide and keep our code nice and simple.
