RF Test Engineer – Advanced Mobile RF Systems
Cambridge, UK

I’m working with a venture-backed, fabless semiconductor company in Cambridge developing genuinely disruptive RF front-end technology for mobile and connected devices.

This is not incremental RF. This is architecture-level change designed to simplify the RF front-end, reduce complexity, and enable scalable, manufacturable solutions for next-generation connectivity.

They’re now hiring an RF Test Engineer to sit at the centre of hardware validation and product development.

This is a hands-on RF measurement and validation position.

You will own the correlation between design intent and measured hardware performance. Your work will directly influence architectural decisions, optimisation strategies, and ultimately what goes into production silicon and modules.

You won’t just “run tests”. You’ll build robust, repeatable RF measurement environments that development engineers trust when making design trade-offs.

The output of this role is simple: clean data, high correlation, and engineering decisions made with confidence.

What You’ll Be Doing
Conduct detailed RF measurements and characterise product performance across development builds
Execute 3GPP-aligned RF measurements (LTE and/or NR), assessing TX/RX behaviour
Develop, maintain and improve repeatable RF test setups for product characterisation
Provide structured, technically rigorous feedback to RF design and systems teams
Participate in design reviews, using measured data to influence decisions
Troubleshoot performance issues at board and module level
Develop automation scripts (Python, MATLAB or similar) to improve repeatability and efficiency
Ensure measurement processes are robust, calibrated, documented and defensible
Support integration, optimisation and system trade-off discussionsThis is a lab-based engineering role. It demands precision, ownership and technical judgement.

What They’re Looking For

Education & Background

Degree in Electrical Engineering, Telecommunications or similar
Strong grounding in RF fundamentalsTechnical Capability

Solid understanding of:

S-parameters
Impedance matching
Gain, noise figure and linearity
Modulation-dependent behaviour
Hands-on experience with:

Network analysers
Spectrum analysers
Signal generators
RF power measurement equipment
Practical experience performing 3GPP LTE and/or NR RF measurements
Experience building and refining repeatable RF measurement setups
Ability to read schematics and interpret RF system-level diagrams
Experience with test automation (Python, MATLAB or equivalent)
Comfortable soldering and reworking PCBs in a lab environmentPersonal Attributes

Detail-driven and disciplined with documentation
Analytical, structured and technically honest
Comfortable working in ambiguity without losing rigour
Able to operate independently but collaborate effectively with design and systems engineers
Resilient when chasing root causes in complex RF behaviourWhy This Role Matters In early-stage semiconductor and module development, measurement quality dictates product quality.

This hire will be central to:

Ensuring high correlation between simulation and hardware
Building trust in lab data
Improving first-time-right design performance
Supporting the path from development to manufacturable productIf you enjoy being the engineer who turns messy RF behaviour into structured, decision-ready data — this will suit you.
