5G Mobile Data Core Junior Operational Engineer (starter)


We open up a world of digital opportunities so people live better and work smarter.

5G will move the Mobile Internet services and applications in a new era. 5G, implemented alongside our other existing mobile technologies (such as LTE), will deliver new services for both residential and business customers. Ultra-fast internet of course, but also new possibilities such as the internet of things (IoT - mMTC), ultra-low latency for VR, AR, self-driving cars, robotics, etc.

A team of 14 experienced engineers is responsible for the maintenance, implementation and adjustment of the entire mobile core network. Very specifically, we are looking for a motivated employee to help evolve the current infrastructure to the new 5G Core.

For this we are looking for a junior engineer profile with potential to develop new technologies, able to learn them very quickly and able to work within an operational team. You will be coached by the team manager and/or a senior engineer.
