• Evaluate and benchmark ML-based solutions against traditional DSP approaches in terms of accuracy, latency, and computational cost.

Job Requirements::
• 3+ years of hands-on experience with deep learning frameworks (PyTorch, TensorFlow, or similar) and neural network architectures (CNNs, RNNs, transformers, autoencoders).

• Experience applying ML/DL to physical layer problems (e.g., channel estimation, MIMO detection, CSI feedback, learned codebooks, or end-to-end learned communication systems) - Advantage.

• Experience in PHY algorithms development for wireless modems - Advantage.

• Familiarity with model optimization techniques for real-time deployment: quantization, pruning, knowledge distillation, and hardware-aware neural architecture search.

• An independent problem solver with excellent mathematical and analytical skills.

• Eager to learn and develop your professional skills in the fields of wireless communications and applied machine learning.

• Team player: Excellent communication skills, and ability to thrive in a global multi-site environment.

• Good understanding of the cellular standards (LTE/NR) - Advantage.

• Experience with ONNX Runtime, TensorRT, or similar inference engines - Advantage.

Education::
• M.Sc / PhD in electrical engineering (major in communication theory and systems, signal processing, and/or machine learning - Advantage).
