The position is based in Stockholm, Sweden.

Responsibilities

Perform system studies in the Radio Physical Layer for functions like Beamforming, Massive MIMO, and emerging 6G technologies.
Specify new 5G/6G system features and functions, including requirements, test cases, algorithms, use cases, and parameter settings.
Develop and use software simulations, primarily link-level, to analyze and optimize the performance of 5G/6G features and signal-processing algorithms.
Contribute to the evolution of 5G/6G standards by analyzing specifications and maintaining compliance.
Support the deployment of new 5G/6G products and features into customer networks.
Work closely with cross-functional development teams on new features, simulations, and improvements.
Explore opportunities to apply AI/ML in radio systems and AI-assisted tools for development workflows.

Requirements

MSc or PhD in Wireless Communications, Telecommunications, Electrical Engineering, Signal Processing, Mathematics, or a related field.
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++.
Strong English communication skills, both verbal and written.
Analytical and result-oriented mindset.
Ability to manage multiple activities and meet deadlines.
Motivated, proactive, and collaborative approach.

Desired Qualifications

Experience developing and analyzing software simulations; knowledge of simulation environments and tools such as MATLAB is an advantage.
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.

Benefits

Opportunity to work on the technologies behind the next generation of mobile communication.
Contribute to innovation and Ericsson IPR, including invention disclosures and patents.
Apply AI/ML in radio systems and AI-assisted engineering.
Work closely with cross-functional development teams, locally and globally.
Ericsson is proud to be an Equal Opportunity Employer.
