We are now looking for a senior system developer (fullstack) for our client Telenor, who wants to work in a technically advanced environment with systems that are at the heart of Telenor's IP network.

You will be part of a competent and stable development team responsible for Telenor's provisioning system – a central part of the network's operations. The team has recently completed major updates to meet regulatory requirements and is now focusing on modernizing and further developing the architecture to meet future needs.

Your role
