🚀 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
