Polytec are seeking a Senior RF Data Scientist / Research Engineer to develop signal-processing and machine learning solutions using RF data from software-defined radios for our Saffron Walden based client. This hands-on role sits at the intersection of RF hardware, DSP and applied ML in a fast-paced RandD environment.

Responsibilities:

  • Analyse and characterise IQ data from SDR platforms
  • Build RF signal analysis and visualisation tools
  • Design RF data-processing pipelines accounting for real-world hardware effects
  • Develop ML and statistical models for RF classification and detection
  • Prototype batch and real-time processing systems in Python and integrate with GNU Radio or C++ backends
  • Support RF data collection and over-the-air testing

    Requirements:

  • Strong Python skills for data analysis and prototyping
  • Solid understanding of digital signal processing fundamentals
  • Experience with SDR frameworks such as GNU Radio or similar
  • Understanding of RF hardware chains and their impact on baseband data
  • Experience analysing wireless protocols or physical-layer behaviour
  • Comfortable working in iterative, experimental RandD environments

    Desirable:

  • Hands-on SDR and RF lab experience
  • Exposure to techniques such as direction finding, Doppler, or beamforming
  • Experience beyond Python (e.g. C++, MATLAB)
  • Knowledge of RF circuits or antenna systems
  • Publications, patents, or open-source contributions

    Please contact us as soon as possible for more details or apply below

Neurodiversity in Robotics Careers: Turning Different Thinking into a Superpower

Robotics is where software, hardware & the physical world collide. From warehouse automation & surgical robots to drones, cobots & autonomous vehicles, robots must sense, think & act reliably in messy real environments. To build that kind of technology, you need people who think differently. If you live with ADHD, autism or dyslexia, you may have been told your brain is “too distracted”, “too literal” or “too chaotic” for engineering. In reality, many traits that made school or traditional offices hard are exactly what robotics teams need: intense focus on complex systems, pattern-spotting in sensor data, creative problem-solving when hardware misbehaves. This guide is written for neurodivergent job seekers exploring robotics careers in the UK. We’ll cover: What neurodiversity means in a robotics context How ADHD, autism & dyslexia strengths map to key robotics roles Practical workplace adjustments you can ask for under UK law How to talk about your neurodivergence in applications & interviews By the end, you’ll have a clearer sense of where you might thrive in robotics – & how to turn “different thinking” into a professional superpower.

Robotics Hiring Trends 2026: What to Watch Out For (For Job Seekers & Recruiters)

As we move into 2026, the UK robotics jobs market is in a strange but interesting place. On one hand, UK manufacturers, logistics firms and warehouses must automate to stay competitive, tackle labour shortages and meet productivity and net-zero targets. On the other hand, the UK still lags badly behind peers in robot adoption, with relatively low robot density in factories compared with other advanced economies – which is both a challenge and a massive opportunity. The National Robotarium +1 Add in AI, computer vision and edge computing, and you get a robotics landscape that is: More selective in hiring. More focused on real operational outcomes. More integrated with software, data and safety standards. Whether you are a robotics job seeker planning your next move, or a recruiter building automation and robotics teams, this guide explores the key robotics hiring trends for 2026.

Robotics Recruitment Trends 2025 (UK): What Job Seekers Need To Know About Today’s Hiring Process

Summary: UK robotics hiring has shifted from toolbox checklists to capability‑driven evaluation that emphasises deployed systems, safety, reliability and total cost of ownership. Employers want proof you can ship and sustain robots in production—industrial arms & cobots, AMRs/AGVs, field robots, surgical/med‑tech, warehouse automation, inspection & maintenance. This guide explains what’s changed, what to expect in interviews and how to prepare—especially for robotics software engineers (ROS/ROS 2), perception/vision engineers, controls & motion planners, mechatronics & embedded, safety & compliance, test/V&V, DevOps/SRE for fleets, and robotics product managers. Who this is for: Robotics software/perception/controls engineers, mechatronics & embedded, simulation & test, DevOps/SRE for robotics fleets, HRI/UX, safety/compliance, field/commissioning engineers, and product/technical programme managers in the UK.
