Visit to the second largest Data Center in Serbia.

Want to peek behind the scenes of cutting-edge technology and discover how our country's second largest data center operates?

During the tour of the CETIN Data Center, you will have the opportunity to confirm or deny everything you thought until now, using the example of one of the best Data Centers in the region. You will find out how much reliability and availability is expected from the Data Center, why system redundancy is important and why energy efficiency is important.

Site visit.

Are you interested in what a design tour looks like before installing a base station?

Join us on a tour of the CETIN location in the vicinity of Belgrade with a team of engineers.

On that occasion, you will find out what challenges engineers face in the field, what things are important to them and what things they look at when deciding whether that location is suitable for them to install a new base station.

From viewing the panorama, the coverage area, looking for the B-side for the microwave link, to choosing the ideal place where the pole will be. We believe that it is important for you, as future engineers, to see everything you have heard in lectures and seen in pictures on the field. 

Your future starts here!

Send us your CV and a short motivational letter by August 28th, in English. In the motivational letter, you can state your grade point average, major at the university and subjects that were most interesting to you.
