5G Software Developer (M/F) - Zagreb, Osijek

Posted date:  May 25, 2023

Zagreb, 21, HR


Ericsson Nikola Tesla Group has nearly 3500 employees, majority of whom are from the STEM field. In addition to our ICT solutions in the telecom sector, we provide innovative solutions in health care, transport, state administration, municipal services and multimedia that improve people’s lives and create new value. With more than 70 years of tradition and continuous work on new technologies, we offer the perfect combination of experience and knowledge. Our Research and Development Center is the strongest and biggest telecom R&D center in the region.


Our Opportunity:


We are looking for software developers who can contribute to Ericsson's market-leading products for creating next-generation 5G mobile networks.


Our SW is the heart of the 5G bloodstream.

It is in constant communication with your mobile device, whatever it is (your mobile phone, car, etc.).

It monitors how your mobile device moves in the network and optimizes all parameters for the best signal and service (user experience).

Our SW within 5G networks will enable several exciting use cases that will improve our lives in the future.


Think about this use case:


A millisecond is 1/1000 of a second.

The average reaction time for humans is 250ms seconds for a visual stimulus, 170ms for an audio stimulus, and 150ms for a touch stimulus. 

Imagine now that your car could react 250 times faster than you.

Imagine it could also respond to hundreds of incoming information and can also communicate its reactions back to other vehicles and road signs all within a few milliseconds.

At 100km/h, the reaction distance is about 30 meters before you pull the brakes.

With a 1ms reaction time, the car would only have rolled a bit less than 3 centimeters.

Our SW will enable that your car has a ubiquitous, fast, and seamless connection as it moves through the network.


This job offers an outlook into an exciting and challenging future where you as a developer will work in a team responsible for the products they develop, from the early phases of ideas and drafts, all the way to customer delivery. 

We are creating an entirely ubiquitous connected world. Products that you develop will be used by hundreds of millions of 5G subscribers worldwide.

Join us and help us create a future!
