🚀 Principal RF Systems Engineer | Advanced Wireless Test & Measurement
We’re a specialist engineering team developing next-generation RF analysis and measurement platforms used to design, validate, and characterise cutting-edge wireless systems.
Our work sits at the intersection of RF hardware, digital design, FPGA engineering, embedded systems, and signal processing — building sophisticated instrumentation from first principles rather than iterating on existing tools.
We’re looking for a Principal RF Systems Engineer to take a leading role in shaping the architecture of new wireless test platforms. This is a hands-on technical leadership position with broad scope across system design, implementation, and validation.
đź“Ť Hybrid (UK-based, Cambridge area) | Flexible working with in-office collaboration required
🔧 What you’ll be doing
* Defining RF and mixed-signal system architectures for new measurement and analysis platforms
* Designing high-performance RF and digital hardware systems operating at GHz frequencies
* Contributing across FPGA, DSP, firmware, or embedded software development where needed
* Leading prototype bring-up, debugging, and system-level validation
* Developing calibration and characterisation approaches for RF performance
* Working closely with cross-disciplinary engineers across RF, digital, software, and signal processing domains
* Providing technical leadership and mentoring within the engineering team
* Driving innovation in wireless test and measurement technology
🎯 What we’re looking for
* Degree in Electronic Engineering, Physics, or a related technical discipline
* Strong background in RF electronics and wireless system design
* Experience specifying and delivering complex RF systems
* Hands-on RF circuit design experience at 2.4GHz or 5GHz - 7GHz frequencies
* Strong understanding of RF metrics (noise figure, linearity, dynamic range, phase noise, etc.)
* Confident using lab equipment (spectrum analysers, VNAs, signal generators, oscilloscopes)
* Experience debugging and characterising high-frequency PCB designs (Altium preferred)
* Ability to operate as both a hands-on engineer and technical decision-maker
🌟 Nice to have
* FPGA development experience (e.g. Xilinx toolchains, Verilog/SystemVerilog/VHDL)
* DSP or communications/modem implementation experience
* Python scripting for automation or test
* Wireless protocols (e.g. short-range or cellular PHY experience)
* Antenna and RF front-end design
* High-speed digital interfaces (USB3, PCIe, etc.)
* Embedded C/C++ development
* PCB layout / signal integrity awareness
đź’ˇ About the role
This is a rare opportunity to work at deep implementation level on advanced wireless instrumentation systems. You’ll help shape architecture and product direction while staying close to the engineering detail — from RF hardware through to digital signal processing and system integration.
The client are paying a high rate of ÂŁ60+ per hour, are happy with majority remote working and the position has been QDOS assessed as OUTSIDE IR35.
If you enjoy solving complex, real-world RF and wireless engineering problems and want to influence how next-generation test systems are built, this is a strong fit.
