About this opportunity:
Predicting the future is fun. Inventing it is powerful. We do both! Ericsson is the leader in bringing 5G to market globally. At RAN Baseband System Management our main task is to describe and specify the wanted behavior of advanced features for the Radio Networks.
We are growing our investments to support 5G deployments across the globe and as part of this we are looking for an experienced Radio Network System Engineer that will join our RAN Baseband System Management team. In our team we work with signal processing, radio resource management, physical layer algorithms, multi-antenna systems, cloud deployments, development of 5G software simulations, supporting the deployment of our 5G products in live networks, and much, much more! We engage with customers, partners, and other Ericsson units to understand technology potential, business needs and market opportunities. We work with standardization in 3GPP and similar fora as global system solutions are important to us to grow markets and reduce cost for society. In order to understand how networks behave, we develop and use simulators to improve signal processing algorithms, but we also analyze performance data from our customers' networks and lead troubleshooting activities. Important technical areas are wireless systems, physical layer algorithms, radio resource management, beamforming, cloud computing, and machine learning/artificial intelligence. System Management is a global organization with units based in Sweden, Canada, USA, Poland, and China. This is a place where you're welcome as your own unique self, and appreciated for the skills, talent, and perspective you bring to the team.
In this role, you will work on projects and processes related to the U.S. market and collaborate with stakeholders based in the United States.
What you will do:
Perform systems studies primarily in Radio Resource Management, e.g. Scheduling, Link Adaptation, time critical communication, and control channel radio resource management.
Specify system features and functions, test cases, algorithms, use cases, parameter settings and address any interactions with legacy features and functionality.
Develop network-level software simulations for the performance analysis of 5G features and algorithms.
Drive continuous improvements of products, simulation tools and processes (feature flow).
Perform solution package (SP) study lead and participate in system trouble report team.
Contribute to advances in 5G standards in terms of 6G readiness.
Contribute to innovation and Ericsson IPR. file invention disclosures and patents.
Support 5G system verification and perform analysis of test results.
Support the deployment of new 5G products and features into customer networks. Work with Customer troubleshooting and analysis. Understand customer configurations and issues.
Work collaboratively on new features, simulations and improvements with cross-functional development and customer engagement teams worldwide.
The skills you bring:
MSc or PhD degree in Computer Science, Electrical Engineering, Engineering Physics or the equivalent level of knowledge. A background in communications theory and digital signal processing is valuable.
Work experience in relevant areas such as 5G NR
An analytical approach with an interest in creativity and innovation
Dedication, self-drive and a strong interest in cooperating with others
An interest to learn and grow your skills continuously being a part of our team
Good knowledge of 5G NR mobile communication systems, especially in the areas of the Physical Layer and Radio Resource Management
Product development knowledge preferably with an understanding of Lean and Agile methods
Software development skills to strengthen product understanding and give an ability to use and develop simulators. Languages include Java, C and C++. Knowledge of simulation environments and tools like MATLAB would be an asset
Excellent communication skills in verbal and written English building positive relationships internally as well as externally.
We work in a hybrid model - 3 days from the office weekly.
What do we offer:
Annual bonus depending on the achievement of the company's goals and results
Possibility to take advantage of the reduction of tax-deductible costs for creative work
Financial awards and distinctions
Private medical care for employee and their family (Medicover)
Life insurance
Mental Help Line

Sports and integration activities (e.g. Football, Joga, raising team, climbing club)
Company support (loans and grants)
Possibility to participate in 3G / 4G / 5G... 6G technology projects
Opportunity to participate in technical and interpersonal training conducted by international trainers
Access to recognized learning platforms (Pluralsight, Skillsoft, Coursera)
Opportunity to work in an international environment, also outside Poland
