Radio frequency design engineer

🚀 RF Hardware Design Engineer

Location: West London

Salary: Up to £60,000

Type: Permanent | Full-Time | On-Site


We’re working with an established technology business that designs and manufactures high-performance RF systems for demanding applications.


They’re now looking for an experienced RF Design Engineer to take ownership of power amplifier development — from first concept through to production-ready hardware.


This is a hands-on engineering role for someone who enjoys building, testing, refining, and shipping real products.


🔧 The Role

You’ll be responsible for developing RF amplifier hardware across low to high power ranges, working closely with electronics, mechanical, and test teams.


Your work will cover:

* Creating end-to-end RF amplifier designs from specification to manufacture
* Running simulations and optimisation for performance, efficiency, and reliability
* Designing RF schematics and multilayer PCB layouts with controlled impedance
* Selecting and integrating active devices, biasing, and protection circuitry
* Building and tuning matching networks and filters
* Supporting antenna integration and impedance matching
* Leading lab validation using industry-standard RF test equipment
* Preparing full technical documentation for release and production
* Managing design revisions, BoMs, and change records


You’ll be deeply involved in both design and verification — this is not a desk-only role.


✅ What We’re Looking For

We’re interested in engineers who bring strong practical RF experience and enjoy working end-to-end.


Essential experience:

* Proven background in RF power amplifier design
* Solid understanding of S-parameters, stability, thermal behaviour, and linearity
* Strong PCB layout skills for RF and mixed-signal designs
* Confident using Pulsonix for schematics and layout
* Experience setting up and interpreting RF measurements (VNA, spectrum, power meters)
* Knowledge of antenna matching and feed networks
* Hands-on prototyping and rework capability
* Ability to produce clear, structured technical documentation
* Willingness to work fully on site


⭐ Nice to Have

Not essential, but highly valued:

* Experience with GaN and LDMOS devices
* Thermal management and mechanical integration knowledge
* Linearisation or feedback techniques
* EMC awareness and pre-compliance testing
* Use of tools such as ADS, AWR, or similar
* Automated testing with Python or equivalent
* Exposure to antenna measurement environments


🎯 What’s in It for You

* Competitive salary up to £60k
* Company pension
* Free on-site parking
* Stable, long-term engineering environment
* Opportunity to work on real-world RF products from concept to launch
