About this vacancy

What we are looking for

At Koodin, we believe in a different way of working in IT: honest, transparent, and with plenty of room for initiative. As a backend developer at Koodin, you work on challenging projects for leading clients, together with a team of experienced professionals. We are looking for people who are not only technically strong, but who also enjoy working together, sharing knowledge, and continuously improving.

What we are looking for

We are looking for strong backend developers who identify with our core values. At Koodin, you get the freedom and trust to bring out the best in yourself. You work as a consultant for various clients, but always with a permanent contract and a close-knit team as your home base. You enjoy variety, like taking responsibility, and gain energy from collaborating and working independently on challenging projects.

This is what you are going to do

Onze consultants worden ingezet op grote, complexe projecten bij diverse toonaangevende organisaties. Je werkt aan digitale transformaties en innovatieve oplossingen die impact maken. Elk project biedt weer nieuwe uitdagingen, samenwerking en groeikansen.

Enthousiast geworden? Neem contact op of stuur je motivatie en cv via onze website. We maken graag kennis met je!

  • Samenwerken en communiceren: Je werkt graag samen in multidisciplinaire teams en kunt je ideeën helder overbrengen.

  • Analytisch en probleemoplossend: Je doorgrondt complexe vraagstukken en komt met pragmatische oplossingen.

  • Vloeiend in Nederlands en Engels

Personal characteristics
