Job description

About The Opportunity

At 5G/6G Baseband System Management, we define how advanced radio network functions should behave in the 5G/6G RAN. Our work spans radio communication, signal processing, system studies, software simulation, 3GPP standardization, baseband architecture, and real customer networks.

Join our Team

We are looking for a Radio Network Systems Engineer to join our team and work on the technologies behind the next generation of mobile communication. You will combine technical analysis and software simulation with system-level thinking, standards work, and collaboration across development teams. You will also have the opportunity to contribute to AI/ML-related developments and AI-assisted engineering, as these technologies become increasingly relevant to future radio systems and development workflows.

What You Will Do

• Perform system studies in the Radio Physical Layer for radio functions such as Beamforming, Massive MIMO, and emerging 6G technologies.
• Specify new 5G/6G system features and functions, including requirements, test cases, algorithms, use cases, parameter settings, and interactions with existing functionality.
• Develop and use software simulations, primarily link-level, to analyse and optimise the performance of 5G/6G features and signal-processing algorithms.
• Contribute to the evolution of 5G/6G standards, including analysing relevant specifications and maintaining our Statement of Compliance.
• Contribute to innovation and Ericsson IPR, including invention disclosures and patents.
• Support the deployment of new 5G/6G products and features into customer networks through network analysis, troubleshooting, and investigation of customer configurations and issues.
• Work closely with cross-functional development teams, locally and globally, on new features, simulations, and improvements.
• Explore opportunities to apply AI/ML in radio systems, as well as AI-assisted tools for simulation, development, analysis, and engineering workflows.

Skills You Bring

• MSc or PhD in a relevant field such as Wireless Communications, Telecommunications, Electrical Engineering, Signal Processing, Mathematics, or a related area.
• Strong background in communication theory, digital signal processing, and mathematics.
• Strong knowledge of LTE, NR/5G, and 3GPP specifications, particularly in the Physical Layer.
• Experience with software development for link-level simulations, using languages such as Python, C, and C++.
• Experience developing and analyzing software simulations; knowledge of simulation environments and tools such as MATLAB is an advantage.
• An analytical and result-oriented mindset, with the ability to investigate complex problems and deliver under pressure.
• Ability to manage multiple activities and meet deadlines while working across different projects.
• Strong English communication skills, both verbal and written, and the ability to explain technical topics and build effective relationships with colleagues and external stakeholders.
• A motivated, proactive, and collaborative approach, with the ability to work independently when needed and contribute effectively as part of a team.
• Interest in AI/ML and AI-assisted engineering is a plus, but strong wireless communication and signal-processing fundamentals are the foundation for the role.

Encouraging a diverse and inclusive organization is core to our values at Ericsson, that's why we champion it in everything we do.

We truly believe that by collaborating with people with different experiences we drive innovation, which is essential for our future growth.

We encourage people from all backgrounds to apply and realize their full potential as part of our Ericsson team.
