- Experience with Python and Shell scripting is expected, familiarity with SQL scripting is a plus.
- Basic exposure to AI/ML concepts (e.g., CNNs, DNNs, RNNs, or Reinforcement Learning) and tools such as TensorFlow or PyTorch is a plus.
- Exposure to AI coding assistants like Amazon Q (or comparable tools) is a plus.
- Knowledge of Linux/Unix development environments, GCC, GDB, Makefile, and inter-process/thread communication.
- Experience with GIT, Eclipse and VSCode.
- Self-driven, proactive learning and innovative mindset.
- Good communication skills; Able to work in English; Japanese language skills are a welcome advantage
- Candidates who have held technical lead roles or who aspire to technical leadership are encouraged to apply.
What we offer
- Be part of a newly established R&D center that will expand our global radio R&D network.
- Opportunities to collaborate with Japan's ecosystem - operators, research labs and universities - to create impactful, large-scale systems.
- Work on cutting-edge software for radios that will be deployed globally in 5G/6G networks.
