Job description

Join our Team

Artificial Intelligence is rapidly becoming a key enabler for future Radio Access Networks. We are looking for an experienced AI in RAN System Developer who is passionate about applying machine learning and advanced analytics to solve real-world telecom challenges.

In this role, you will contribute from early phase systemization to development of AI-enabled RAN functions that improve network performance, optimize resource utilization and enhance the end-user experience. The focus is on AI for RAN functionality and embedded.

You will work with some of the industry’s most advanced Radio Access Network technologies, including latest NR Advanced capabilities, while contributing to the journey toward 6G and AI-native networks. Working alongside experts in RAN architecture, radio algorithms, system design, software development and research, you will help shape how AI becomes an integral part of future wireless systems.

This is an opportunity to combine cutting-edge Machine Learning with carrier-grade radio technology, where solutions must be productized and executed efficiently within strict real-time, compute, memory, power and latency constraints.

What you will do

• Drive the system design of AI/ML-enabled RAN functions and algorithms, ensuring that machine learning techniques can be productized and executed efficiently within real-time RAN systems.
• Analyze data and translate insights into deployable capabilities that can improve network efficiency, latency, throughput, capacity, reliability and user experience.
• Design meaningful experiments, data collection strategies and validation methodologies to assess the effectiveness, feasibility and product impact of AI-driven solutions.
• Evaluate technical and business problems and determine when machine learning provides value compared with classical algorithmic approaches, avoiding indiscriminate use of AI.
• Work closely with engineering teams to integrate AI solutions into existing RAN products, software platforms and development flows, from early prototype and proof-of-concept work to production-quality implementation.
• Optimize AI models for deployment under finite CPU, memory, power and latency budgets, balancing AI accuracy against computational cost and operational value.
• Contribute to the evolution of AI methodologies, lifecycle practices, tooling and best practices for RAN products and future AI-native networks.

The skills you bring

• Master’s degree in Computer Science, Electrical Engineering, Applied Mathematics, Telecommunications or a related discipline.
• Strong Machine Learning fundamentals, including supervised, unsupervised and reinforcement learning, feature engineering and feature selection, model training, validation, performance evaluation, statistical analysis and data-driven decision making.
• Experience with resource-constrained systems, including the ability to design models that fit within finite CPU, memory, power and latency budgets.
• Understanding of inference optimization, model compression, quantization, pruning, acceleration techniques and deployment feasibility on embedded or telecom platforms.
• Strong software engineering skills, including modern C++, Python for AI experimentation and prototyping, software architecture understanding, CI/CD and the ability to move from prototype to production software.
• Understanding of telecom and RAN systems, preferably within areas such as scheduling, mobility, link adaptation, RRM algorithms, O&M systems or performance management.

Behavioral competencies

• Analytical and data-driven, with the ability to understand complex technical problems and extract actionable insights.
• Innovative and curious, with a continuous improvement mindset and the ability to explore new solutions and assess their performance in real-life networks.
• Critical thinker who can assess technical trade-offs and evaluate alternative approaches pragmatically.
• Collaborative team player who enjoys working across system architecture, software, feature ownership, research and product development boundaries.
• Intrinsically motivated, with ownership, learning agility and a strong drive to deliver business and customer value.

What Success Looks Like

A strong candidate can demonstrate achievements where AI algorithms, optimization strategies or Machine Learning models have delivered measurable improvements in RAN or similarly constrained technical environments. Examples may include improved network efficiency, reduced latency, increased throughput or capacity, enhanced predictive maintenance, improved system uptime or better user experience during demanding traffic conditions.
