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.
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
- 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
- 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
- Embedded C/C++ development
- PCB layout / signal integrity awareness
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 £60+ 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.
