Job description

Job Description

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 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 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
