System Developer

Join our Team 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. 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.
