PDU CD - C++ Developer Intern

Job Description

Date: Sep 19, 2019

Being a student at Ericsson is special. We give you the knowledge to learn, challenging tasks to grow yourself, and the opportunity to work on projects that change the future of technology in telecommunication.


You’ll only get to start your career once. Let’s make it a good one.


Ericsson Hungary is looking for PDU CD – C++ Developer Intern.


Our team is part of the "Middleware IP and OS" (MIPOS) development center in the PDU Component Development  (PDU CD). We are responsible for developing components to one of our product: Component Based Architecture (CBA) that is used mostly by other Ericsson applications. These components are: eVIP, Database Services (DBS; holding DBN and DAS), vDicos and C-Diameter. All components are written in C\C++.


Component Based Architecture (CBA): CBA is Ericsson's latest generation of strategic telecommunication platform.

  • Secures the services which were provided by previous platforms (fast, reliable, scalable cluster architecture, fast data access and flexible load distribution)
  • Based on standard APIs. (Often integrates "free and open source" software).
  • More and more applications of Ericsson (CUDB, MTAS, CSCF, DSC, CCN...) are running on CBA platforms, both native and virtual / Cloud environments.


In Hungary, we are looking for developer interns for the following components:

  • DBN (DataBase Newgeneration): A distributed, object-oriented NoSQL, database management component implemented in C ++ that provides the fastest, fault-tolerant data access for applications running on Linux clusters.  DBN is developed in C++ under Linux using git and Jenkins, and is deployed on virtualized clusters. 
  • vDicos (DICOS virtual machine): Eco-system supporting development and runtime execution of telecom grade application business logic written in C++ targeting CBA based deployments (user applications: HSS, MTAS, CSCF, etc). It is the next generation evolution of the Ericsson Telecom Server Platform (TSP).
  • C-Diameter: Standard implementation of Diameter signaling management system for CBA components and CBA based application. Written in C++ 11 in a platform-independent way to easily support CBA and ADP architecture
  • We have already started to work with the implementation of the new generation of these components which will follow Ericsson’s microservice based cloud native architecture (ADP)


What will you do:

The above-mentioned components are being developed in Hungary, and we work together with Swedish colleagues on other components.  Your task as a cross-functional member of our team will be to help maintaining and port the current CBA solution into a microservice-based architecture. Since we want to keep building an agile organization, our team members should be capable of writing code and test as well.


Apply if you are/have:

  • ongoing BSc/MSc studies with at least one more year remaining at a Hungarian university
  • srong programming and troubleshooting experience in C++ preferably on Linux
  • experience in concurrent programming
  • understanding of distributed systems
  • experience with using virtualization technologies is an advantage (KVM, VirtualBox, VMware)
  • flexible mindset and clear quality focus
  • real team-player and open to learn
  • feeling homey in agile way of working
  • a clear customer focus
  • good knowledge in English, both written and spoken


What we offer
