RF Data Scientist / Research EngineerAn exciting opportunity for an RF-focused Data Scientist / Research Engineer to join a stealth-mode start-up developing novel UAV/detection systems. This role offers the chance to work at the cutting edge of RF hardware, software-defined radio, and intelligent signal processing — helping shape the next generation of real-world RF sensing systems.This company is tackling some of the world’s most pressing challenges, founded by a team of exceptional Engineers who have already realised success with other ventures. The environment is one of deep tech innovation and collaborative problem solving.Location: 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)Salary: Up to £65,000 per annum (may be more for an exceptional candidate)Requirements for RF Data Scientist / Research Engineer: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 filteringHands-on experience working with SDR platforms such as bladeRF, USRP, HackRF, or similarPractical knowledge of RF hardware chains (e.g. antennas, ADCs, filters, mixers, gain stages, LO, AGC) and how these impact signal dataExperience building RF signal characterisation and diagnostics tools, e.g. constellation tracking, time-frequency plots, autocorrelation analysisFamiliarity with tools such as GNU Radio, SDRangel, SoapySDR, ZMQUnderstanding 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 identificationMUST be eligible for SC Clearance due to the nature of the workResponsibilities for RF Data Scientist / Research Engineer:Analyse complex IQ data from SDR hardware in real-world RF environmentsBuild signal processing pipelines that work within hardware and software constraintsDevelop tools to visualise and diagnose signal behaviour and system performancePrototype real-time and batch-processing architectures using Python and signal processing librariesLead field-based data collection and over-the-air experiments using drones and wireless devicesCollaborate with a multidisciplinary team to develop SDR-based detection and intelligence solutionsModel and mitigate hardware-induced effects to improve signal fidelity and inference outcomesWhat this offers:An opportunity to shape an innovative product at the interface of RF and MLWork with an exceptional technical team in an early-stage R&D environmentDeep technical variety across software-defined radio, machine learning, and signal intelligenceCompetitive package and future leadership potentialApplications:If you would like to enquire about this unique RF Data Scientist / Research Engineer opportunity, we would love to hear from you.
