About this vacancy

Introduction

At Koodin, we believe in a different way of working in IT: honest, transparent, and with plenty of room for personal initiative. As a back-end developer at Koodin, you will work on challenging projects for leading clients, alongside a team of experienced professionals. We are looking for people who are not only technically strong, but also find joy in collaboration, knowledge sharing, and continuous improvement.

Who we are looking for

We are looking for strong back-end developers who recognize themselves in our core values. At Koodin, you get the freedom and trust to get the best out of 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 love variety, like to take responsibility, and get energy from collaborating and working independently on challenging projects.

This is what you are going to do

Our consultants are deployed on large, complex projects at various leading organizations. You will work on digital transformations and innovative solutions that make an impact. Each project offers new challenges, collaboration, and growth opportunities.

Excited? Get in touch or send your motivation and CV via our website. We look forward to meeting you!
