  • Analyse and characterise IQ data from SDR platforms
  • Build RF signal analysis and visualisation tools
  • Design RF data‑processing pipelines accounting for real‑world hardware effects
  • Develop ML and statistical models for RF classification and detection
  • Prototype batch and real‑time processing systems in Python and integrate with GNU Radio or C++ backends
  • Support RF data collection and over‑the‑air testing

Requirements

  • Strong Python skills for data analysis and prototyping
  • Solid understanding of digital signal processing fundamentals
  • Experience with SDR frameworks such as GNU Radio or similar
  • Understanding of RF hardware chains and their impact on baseband data
  • Experience analysing wireless protocols or physical‑layer behaviour
  • Comfortable working in iterative, experimental RandD environments

Desirable

  • Hands‑on SDR and RF lab experience
  • Exposure to techniques such as direction finding, Doppler, or beamforming
  • Experience beyond Python (e.g. C++, MATLAB)
  • Knowledge of RF circuits or antenna systems
  • Publications, patents, or open‑source contributions

How Many Machine Learning Tools Do You Need to Know to Get a Machine Learning Job?

Machine learning is one of the most exciting and rapidly growing areas of tech. But for job seekers it can also feel like a maze of tools, frameworks and platforms. One job advert wants TensorFlow and Keras. Another mentions PyTorch, scikit-learn and Spark. A third lists Mlflow, Docker, Kubernetes and more. With so many names out there, it’s easy to fall into the trap of thinking you must learn everything just to be competitive. Here’s the honest truth most machine learning hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool. They hire you because you can solve real problems with the tools you know. Tools are important — no doubt — but context, judgement and outcomes matter far more. So how many machine learning tools do you actually need to know to get a job? For most job seekers, the real number is far smaller than you think — and more logically grouped. This guide breaks down exactly what employers expect, which tools are core, which are role-specific, and how to structure your learning for real career results.
