RF Data Scientist / Research Engineer

Saffron Walden, UK – primarily on-site due to the hands‑on nature of the work (some hybrid flexibility may be considered depending on the individual and stage of development)

Up to £65,000 per annum (may be more for an exceptional candidate)

• 
  
• Strong Python skills for data analysis and prototyping (e.g. NumPy, SciPy, matplotlib, PyTorch, scikit‑learn)
  
• Excellent understanding of digital signal processing techniques — including FFTs, resampling, modulation and filtering
  
• Hands‑on experience working with SDR platforms such as bladeRF, USRP, HackRF or similar
  
• Practical knowledge of RF hardware chains (e.g. antennas, ADCs, filters, mixers, gain stages, LO, AGC) and how these impact signal data
  
• Experience building RF signal characterisation and diagnostics tools, e.g. constellation tracking, time‑frequency plots, autocorrelation analysis
  
• Familiarity with tools such as GNU Radio, SDRangel, SoapySDR, ZMQ
  
• Understanding of wireless protocols and physical‑layer signal structures (e.g. Wi‑Fi, LTE, LoRa)
  
• Ability to design machine learning or statistical models for signal classification, anomaly detection or emitter identification
  
• Must be eligible for SC Clearance due to the nature of the work
  

• 
  
• Analyse complex IQ data from SDR hardware in real‑world RF environments
  
• Build signal processing pipelines that work within hardware and software constraints
  
• Develop tools to visualise and diagnose signal behaviour and system performance
  
• Prototype real‑time and batch‑processing architectures using Python and signal processing libraries
  
• Lead field‑based data collection and over‑the‑air experiments using drones and wireless devices
  
• Collaborate with a multidisciplinary team to develop SDR‑based detection and intelligence solutions
  
• Model and mitigate hardware‑induced effects to improve signal fidelity and inference outcomes
  

• 
  
• An opportunity to shape an innovative product at the interface of RF and ML
  
• Work with an exceptional technical team in an early‑stage R&D environment
  
• Deep technical variety across software‑defined radio, machine learning and signal intelligence
  
• Competitive package and future leadership potential
