Being a Senior Developer at Ericsson Hungary

I have been at Ericsson since 2007 and I am currently a Senior Test Engineer after working in various different roles such as 3rd Line Support Engineer and Test Engineer. I joined becuase I wanted to be part of a team that is a major player in the telecommunication industry. Ericsson is key player in evolution of mobile networks and is paving the way in many new technologies such as 5G, IOT, Cloud, AI.  It is also one of the largest companies in Hungary in the telecommunication field and software R&D. In addition, it also supplies the 5G mobile network for one of the largest operators in Hungary. All this makes it a great place to be if you want to be at the forefront of telecommunications.

Here are the top three things which I really appreciate working at Ericsson.


The culture at Ericsson is open, friendly, and welcoming. I have made many friends with people from around the world, these friendships have continued despite us no longer working together. I am still friends with people I worked with on my very first project at Ericsson. When I first entered the building, I could feel people were very easy to talk to and friendly. This hasn’t changed in the 15 years I have been here.

There are social events like football championship, it’s like a big party with food and drink. The company takes part in “Researchers Night” where students or people interested in the company can have a look at what we do.


Ericsson being a leader in the telecommunications industry means I can work with technologies that are forming our world, such as the 5G core network which enables IoT, and enables remote communication between things like cars and facilitates remote doctor consultations.

I get the opportunity to work with, and work on a range of technologies in my role including 4G, 5G, Evolved Packet Gateway (EPG), Packet Core Gateway (PCG), and tools such as Linux, JCAT, Java, Python, C/C++, Kubernetes and Ericsson Cloud Execution Environment.

In our cross functional team, we work on features for the User Plane Functions which is a part of the 4G and 5G core network. Our work directly affects the mobile users around the world. That is the best thing about what I do, I work on things which are used every day and on things that are creating the future.

Career Progression and Training

I have received a lot of support throughout my time at Ericsson to change roles, develop my careers and learn new skills. It is easy to switch between projects and my managers always supported me in this when I wanted to learn new technologies.

In terms of training, I get more than enough opportunities to improve my skills and learn new ones. Before Covid, we used to have off site training; these kind of trainings are costly, if I worked for smaller company they may not be able to provide these. The training is not only solely about technical skills but also soft skills, for example, I recently did training in communicatins feedback to better understand how to give feedback.
