The Fraunhofer-Gesellschaft ( www.fraunhofer.com ) currently operates 76 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 32 000 employees work with an annual research budget of 3,4 billion euros. Our »Broadband and Broadcasting« department drives the development of new technologies for wireless communication systems. Our services include system design and analysis, waveform design and algorithm development, real-time prototype implementation (hard- and software), protocol design, and complete system validation. Are you interested in developing high-performance 5G and 6G communication systems ‒ from the basics to end-to-end demonstrators for detailed technology evaluation? Then you should definitely take a look at our offer You will concentrate on system design and analysis, waveform design and algorithm development, as well as simulation verification in the 5G/6G environment. To this end, you will use C/C++ to implement and test signal processing on the open source platform »OpenAirInterface 5G«, primarily on the physical and medium access control (MAC) layers. Last but not least, you will analyze the latest 5G/6G technologies released by 3GPP by utilizing the developed real-time capable prototypes as well as powerful lab equipment (e.g., channel emulators, over-the-air technology, or live satellites). A scientific university degree in communications engineering or a comparable degree program Good knowledge of 4G and 5G mobile radio systems, preferably also in 3GPP 5G NR or LTE. Expertise in communication systems (physical layer or MAC layer), C programming (preferably also C++), Linux, embedded software development, version control systems (Git, Apache Subversion), and laboratory/field tests. Ideally, a basic understanding of the OpenAirInterface, software architecture, and MATLAB for communication systems, as well as experience using scripting languages. (Perl, TCL, bash/csh). Strong verbal and written communication skills (German and English). Fraunhofer is not only the largest organization for applied research (application-oriented research organisation) in Europe, but also a top-rated employer. But why?
