We’re supporting a Bristol based client who develops high-performance microwave amplifier systems for mission-critical applications – from defence and aerospace to research and test & measurement.
This is a rare opportunity to join an expert design team where your focus will be on developing broadband and narrow band PA solutions from 20 MHz up to 20 GHz. You’ll play a key role in shaping next-generation RF front-end designs and solving complex performance challenges using technologies such as GaN, GaAs, and LDMOS.
The Role – Senior RF Engineer
You’ll be responsible for the full design lifecycle of linear and non-linear RF PAs, supporting both new product development and the continuous improvement of existing amplifier platforms. The ideal candidate will bring strong experience with device-level modelling, matching networks, stability analysis, and thermal performance considerations in high-frequency systems.
Key Responsibilities:
* Design, simulate and optimise RF power amplifiers from 20 MHz to 20 GHz
* Carry out schematic capture, layout guidance, and hands-on lab testing
* Work closely with mechanical, systems and digital engineers to ensure full integration
* Conduct performance testing using VNAs, spectrum analysers and load-pull systems
* Provide technical input across prototype development and product industrialisation
About You:
* Strong background as a Senior RF Engineer or equivalent in a relevant domain
* Extensive experience in power amplifier design using GaN, GaAs or LDMOS
* Skilled in RF simulation tools (e.g., ADS, AWR, HFSS, CST)
* Comfortable in a hands-on lab environment – from breadboarding to production-ready systems
* Experience working on broadband and/or high-power microwave amplifier systems
This is an on-site role based in Bristol, within a well-equipped facility where engineering is at the heart of the business. Youll join a technically impressive team who are pushing performance boundaries in the RF and microwave space.
