Hardware & RF Test Engineer
Location: Cambridge / Hybrid
About the position
Our client is developing fixed wireless access equipment based on the 5G NR air interface, operating at mmWave frequencies. Its products combine gNB access points, customer premises equipment, and network management systems for long-range wireless connectivity.
The Hardware & RF Test Engineer will primarily develop, build, and maintain board-level and system-level test environments for this equipment. The role combines hands-on RF measurement, test method development, verification and validation, automated test definition, and fault investigation across controlled laboratory and over-the-air environments.
This is a practical test engineering position with responsibility for establishing test infrastructure, executing tests against product requirements, and investigating failures across RF, analogue, digital, and power domains.
What you will be working on
The Hardware & RF Test Engineer will support product development through board-level and end-to-end system testing, including:
- Developing hardware and RF test infrastructure for controlled laboratory and over-the-air testing.
- Creating test methods to validate baseband and RF hardware designs at board and complete-product level.
- Performing conducted and radiated RF measurements on mmWave equipment, including measurements down to baseband.
- Defining test cases for automated scripts supporting system and acceptance testing of 5G NR gNB, UE, and associated product building blocks.
- Executing verification and validation tests against product requirements, recording results, and reporting defects.
- Analysing test data and investigating root causes across power, digital, analogue, IQ, IF, and RF signal domains.
- Building demonstration environments that show product features and performance through conducted and radiated testing.
- Selecting and procuring suitable test equipment, software, and laboratory materials, while maintaining test systems for reliable and repeatable operation.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The test environment includes spectrum and signal analysis, receive sensitivity, output power, adjacent-channel measurements, range-versus-performance testing, and beamforming or beam-management evaluation over simulated distances. Board-level measurements include power consumption, phase noise, EVM, and digital and analogue signal quality.
What our client is looking for
For this Hardware & RF Test Engineer position, our client is looking for someone with experience in:
- Hardware and RF testing within modern wireless communications equipment.
- Using spectrum analysers, signal generators, high-speed oscilloscopes, power meters, and related laboratory instrumentation.
- Conducted and radiated testing, including anechoic chambers, antennas, and beamforming technologies.
- Developing system test strategies and test methods for wireless products.
- Digital modulation, IQ, IF, and RF interfaces, and both high- and low-frequency measurements.
- Analysing eye diagrams, constellation diagrams, and RF measurement results to identify faults.
- Debugging analogue, digital, and power circuitry within wireless radio hardware.
