Wireless Systems Software Engineer

What will you do:

• Contribute to the development of a modular, multi-RAT RAN digital twin covering LTE and 5G NR.

• Develop and integrate production software components with simulation and analysis tooling using stable and maintainable interfaces.

• Work with software and system teams to model communication-system behavior, including traffic, mobility, scheduling, interference, and performance KPIs.

• Support the extension of existing LTE simulation capabilities and reusable components for additional radio technologies.

• Develop software components and tools in C/C++ and Python for simulation, automation, data processing, and analysis.

• Support the development and evaluation of AI/ML-based capabilities for communication systems and network optimization.

• Build datasets, experiment pipelines, and automated analysis tools to evaluate system behavior and algorithm performance.

• Create reproducible tests and experiments across software builds and algorithm versions using defined scenarios, configurations, and KPIs.

• Support simulation verification and validation activities, including comparison with lab results and analysis of model behavior.

• Build automated unit, component, end-to-end, regression, and performance tests and integrate them into CI/CD workflows.

• Improve simulation speed, usability, observability, and automation so engineering teams can run repeatable experiments independently.

• Debug issues across C/C++, Python, MATLAB, system software, configuration, and reference measurements.

• Document assumptions, supported scenarios, limitations, and experiment results in a clear and structured way.

• Work closely with RAN, PHY, system, AI/ML, automation, and validation teams to turn engineering questions into measurable experiments.

What you bring:

• B.Sc. in Electrical Engineering or an M.Sc. in a relevant field.

• At least 2 years of hands-on software development experience in communication systems or a related telecom environment.

• Strong software development skills in C or C++ and Python.

• Good understanding of communication systems and the ability to learn new technologies and system concepts quickly.

• Experience working in Linux development environments with Git, automated testing, and modern software development practices.

• Strong analytical and problem-solving skills, with the ability to investigate complex technical issues independently.

• Good communication skills and the ability to work effectively with software, system, algorithms, and validation teams.

• Simulation experience is not required; candidates with strong software and communication-system backgrounds are encouraged to apply.

Nice to have:

• Experience with simulation environments, system-level modelling, or hardware-in-the-loop testing.

• Knowledge of LTE and/or 5G NR, RAN, modem/PHY, or wireless communication systems.

• Experience with MATLAB and communication-system simulation or analysis tools.

• Hands-on experience with scientific computing and data analysis using NumPy, SciPy, pandas, or similar tools.

• Exposure to AI/ML, time-series analysis, signal processing, or network optimization.

• Familiarity with PyTorch, TensorFlow, Hugging Face, or other machine-learning frameworks.

• Knowledge of digital communications and signal processing concepts.

• Experience with automated testing, containers, CI/CD, or cloud development environments.

• Familiarity with SDR, radio test equipment, lab automation, or field-log analysis.
