Polytec are seeking a Senior RF Data Scientist / Research Engineer to develop signal-processing and machine learning solutions using RF data from software-defined radios for our Saffron Walden based client. This hands-on role sits at the intersection of RF hardware, DSP and applied ML in a fast-paced RandD environment.

Responsibilities:

• 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
