An 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: Market competitive. The hiring manager prefers to keep this open to understand candidates’ expectations in relation to their individual experience. They believe this avoids setting a base or ceiling that could deter strong applicants.
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 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
Responsibilities for RF Data Scientist / Research Engineer
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
What this offers:
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
