Your tasks

We believe that you are a skilled and ambitious person and you have been working with IoT solutions for several years. As an hands-on architect you will work with architecture, design, security and implementation of IoT systems.

You are eager to take part in every part of innovation from evaluation, proof of concept until final delivery and putting a solution in to a production.

We expect you to do great work, both as part of a team and independently.
