What you'll do
Do you love building digital environments and web applications that - literally - everyone can enjoy? Does that include the development and documentation of complex systems? Do you especially enjoy sparring sessions with developers, architects and designers? In that case, iO might just hold the perfect spot for you at our campus in Sofia, Bulgaria.
At iO, you’ll find yourself in an international organization that looks and feels closely connected, thanks to our hybrid way of working and cosy campuses, open to all employees, across Belgium, the Netherlands, Sweden and Bulgaria. In that culture of open, cross-campus communication and collaboration, you’ll find yourself in a self-managing Scrum team, composed of colleagues and clients alike.
You optimize our current platforms and develop new customized solutions and features. As you develop your way into iO history, you’re always on the lookout for new techniques to introduce to your team. You're vocal during standups and like to share your ideas with the rest. This is - in fact - just one way of showing you’re a team player with good communication skills, one who is eager to learn quickly and use new technologies
Even with your .NET experience, you know there’s always plenty to learn. That’s why we support you in your development. Not only within your professional field but also on a personal level. Think, for example, of soft-skills training, Expert Groups and certificates, or inspiring events.
