Senior RF Data Scientist / Research Engineer – Near Cambridge
My client, a fast-growing AI company based near Cambridge, is seeking a Senior RF Data Scientist / Research Engineer to work at the intersection of RF hardware, digital signal processing, and machine learning. This hands-on R&D role involves analysing complex RF datasets, developing advanced signal-processing pipelines, and contributing to cutting-edge UAV/drone detection technologies.
You will play a key role in prototyping new sensing capabilities, working with SDRs, designing real-world RF experiments, and integrating machine-learning models into early-stage hardware–software systems. This position is ideal for someone who thrives in fast-paced, iterative prototyping environments.
Key Responsibilities
Analysing raw IQ data from SDR platforms (e.g., bladeRF, USRP) to extract, classify, and interpret RF signal features
Building diagnostic RF analysis tools (time–frequency plots, cyclic spectra, EVM, autocorrelation, constellation tracking, etc.)
Designing RF data-processing pipelines built around practical hardware constraints (bandwidth, ADC limits, gain stages, timing jitter)
Modelling RF front-end behaviour (filters, mixers, LOs, AGC, noise figure) to improve signal integrity and inference accuracy
Developing ML and statistical models for RF classification, anomaly detection, and emitter identification
Prototyping real-time or batch-processing systems in Python (NumPy, SciPy, PyTorch) with potential integration via ZMQ, GNU Radio, or C++ backends
Leading RF data collection, field experiments, and over-the-air testing using drones, wireless devices, and custom transmitters
Requirements
Strong Python proficiency for RF data analysis and prototyping (NumPy, SciPy, matplotlib, scikit-learn, PyTorch)
Solid understanding of DSP fundamentals (FFT, filtering, modulation, correlation, noise modelling, resampling)
Familiarity with SDR frameworks such as GNU Radio, SDRangel, osmoSDR, or SoapySDR
Practical understanding of RF hardware chains (antenna → filters → mixers → ADC) and their impact on baseband data
Experience analysing wireless protocols (Wi-Fi, LTE, LoRa, etc.) and physical-layer structures
Comfortable debugging SDR setups and performing field-based RF data collection
Strong communication skills and ability to work effectively within an iterative R&D team
Desirable
Hands-on experience with SDRs (bladeRF, HackRF, USRP, PlutoSDR) and RF lab equipment (spectrum analysers, VNAs, signal generators)
Experience in passive radar, beamforming, TDoA, Doppler, or direction finding
Familiarity with embedded or real-time systems (FPGA pipelines, GPU acceleration, etc.)
Programming experience in MATLAB, C++, Rust, or similar languages
Knowledge of RF circuit principles (impedance matching, filter design, gain budgeting)
Experience designing or testing antenna arrays for sensing/detection
Publications, patents, or open-source RF/ML contributions
Role Details
Location: Cambridge area (onsite or hybrid depending on project needs)
Department: Research & Prototyping Team
Impact: Direct involvement in early-stage hardware–software product development
