Job Description

Date: Jan 10, 2019

Ericsson Research develops new communication solutions and standards. The organization has responsibility to provide Ericsson with world-class system concepts, technology innovations, and methodology. Rapidly increasing demands for mobile broadband access in combination with needs for new technology and solutions for scenarios motivated by the ongoing transformation of society into a society where everything that benefits from being connected will be connected creates challenging and exciting opportunities for our organization. Building on our experience from real network operations, profound knowledge about existing standards, and forward-looking research, we invent and master advanced concepts and solutions that shape today’s and tomorrow’s mobile radio communication.


Job description

Within Ericsson Research, Research Area Radio is responsible for providing advanced system and signal processing concepts and solutions, including antenna concepts and solutions, targeting standardization of radio access systems as well as implementation in network nodes and in user or machine terminals. As Researcher within the Radio department, you will be part of investigating and evaluating concepts and solutions for future radio access technologies and standards, such as NR. You will also be part of the continuous development and improvement work of existing standards, such as LTE and WiFi. Mastering physical layer techniques is key (multiple access technologies, modulation, channel coding, parameter estimation, multi-antenna transmitter and receiver algorithms, etc.). Using simulation tools as means of evaluation is natural part of the work. Understanding the interaction between link and system performance, to ensure that proposed access solutions are enabling efficient overall performance is also crucial. Furthermore, understanding hardware possibilities and limitations, based on today’s and tomorrow’s technologies is important. Over time our staff will work with algorithm design, model and simulator tool development, simulations, concept design and standardization. A wide range of additional opportunities, such as testbed implementation and field performance tasks, exist as well. This approach enables each researcher to develop a truly broad competence and a holistic view. The work is performed in projects that may incorporate internal and external research collaborations.
The available Researcher position will strengthen our research on communication concepts for, e.g., mobile broadband, machine type communication, broadcast, device-to-device communication, and shorter-range communication solutions. It could also include standardization of the above-mentioned areas.



We are looking for highly competent and driven researchers with competence and experience in signal processing, control theory, wireless communications, and communications hardware. The position requires a M.Sc. or Ph.D. degree, or similar, preferably with demonstrated experience and knowledge in the above mentioned required competences. Strong analytical skills and ability to acquire new knowledge and apply it in the job are important. Skills in simulation and evaluation tool methodology and structured object-oriented programming, such as C++ and Matlab, is desirable, as computer simulations will be natural parts of the work in addition to analytical evaluations. Interest in leadership and leadership experience are further qualifying, and since daily collaboration and interaction with other skilled researchers are the basis for our ways of working, having team skills is a necessity.
At a personal level, you are good at communicating and like teamwork. You should be fluent in written and spoken English. You should enjoy working with people having diverse backgrounds and competences. You should also have the ability to handle theoretical and practical research as well as the development aspects of the work. It is important that you have strong personal drive and a strong focus on the tasks at hand.
We are looking for both experienced people and newly graduated M.Sc. and Ph.D.


If you have any specific questions you are welcome to contact Malin Hessel  Recruitment Specialist  at
