About This Opportunity

Mobile networks are today seen as being part of the critical infrastructure of societies. Security and privacy are essential for protecting the communication in mobile networks, and to ensure availability of the services offered on top of the mobile networks.

Our researchers work with security for future mobile networks, taking into account new use cases and services for mobile networks. A security researcher needs to understand the systems that the security is built for. Thus, security research offers a great opportunity to work with the latest technology.
