Backend Development internship

Job description

On our team, you will be designing, developing, and supporting the core functionality that drives our platform using the latest technology available. The Fonto XML Editor is fully developed in JavaScript. It consists of three parts; the user interface, an intermediate layer, both written in JavaScript and React and the core, which is built from different components written in Vanilla JavaScript or TypeScript.

The product you are building is complex and quality of code is super important! So expect test automation, unit testing and delivery automation practices. This ensures that you bring a high quality product to the market that adds real value to the end user. Technology is the focus of the company and therefore, you as an engineer, are a core asset. This means this company understands the importance of you, your ideas, development and overall wellbeing.
