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

How Many UAV Tools Do You Need to Know to Get a UAV Job?

If you’re aiming for a role in the Uncrewed Aerial Vehicle (UAV) industry, it can feel like every job advert expects you to know a never-ending list of tools: flight control systems, autopilot frameworks, simulation platforms, sensor suites, communication stacks, mission planning software, GIS tools — and on it goes. With so many names and acronyms, it’s easy to feel overwhelmed and assume you must learn every tool under the sun before you’ll be taken seriously by employers. Here’s the honest truth most UAV hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool — they hire you because you can use the right tools to solve real UAV problems safely, reliably and in context. Tools matter — absolutely — but they always serve a purpose: solving problems, reducing risk, improving performance, or guiding safer operations. So the real question isn’t how many tools you should know — it’s: which tools you should master, in what context, and why. This article breaks down what employers actually expect, which tools are essential, which are role-specific, and how to focus your learning so you look credible, confident and job-ready.

What Hiring Managers Look for First in UAV Job Applications (UK Guide)

Whether you’re aiming for roles in UAV design, robotics/controls engineering, autonomy & computer vision, flight test & certification, embedded systems, operations, ground control software, systems integration or regulatory compliance, the way you present yourself in an application can make or break your chances — and that often happens before the hiring manager reads past your first few lines. In the UK UAV/jobs market, recruiters and hiring managers scan applications rapidly. They look for relevant experience, measurable delivery, technical credibility, domain awareness and safety/regulatory understanding — often making a decision within the first 10–20 seconds. This guide breaks down exactly what hiring managers look for first in UAV applications, why those signals matter, and how to structure your CV, portfolio and cover letter so you get noticed — not filtered out.

The Skills Gap in UAV Jobs: What Universities Aren’t Teaching

Unmanned Aerial Vehicles (UAVs) — commonly known as drones — are among the fastest-growing technologies globally. From infrastructure inspection and agriculture to emergency response, surveying, logistics and defence, UAVs are transforming how organisations gather data, deliver services and improve efficiency. In the UK, demand for UAV professionals is increasing rapidly. Yet despite a growing number of graduates with engineering, robotics or aerospace backgrounds, employers continue to report a persistent problem: Many graduates are not ready for real UAV jobs. This is not a reflection of intelligence or academic effort. It is a widening skills gap between what universities teach and what employers actually need in the UAV sector. This article explores that gap in depth — what universities do well, where programmes fall short, why the divide exists, what employers actually want, and how jobseekers can bridge the gap to build a successful career in UAVs.
