Our client is a growing RF and microwave technology business based in Sedgefield, developing advanced products for demanding space, defence and communications applications.
They are looking for an experienced Senior MMIC Design Engineer to work on high-frequency devices operating from 37GHz to 115GHz and beyond. The work is technically challenging, commercially relevant and supported by strong internal RF, microwave, systems and test capability.
As a Senior MMIC Design Engineer, you will take ownership of MMIC development from initial architecture and circuit design through to fabrication, testing and production release.
Your work will include:
Designing and laying out MMICs using GaAs, GaN and InP technologies
Developing LNAs, power amplifiers, gain blocks, frequency converters, attenuators and multipliers
Selecting suitable semiconductor processes for new products
Completing circuit simulation, optimisation and design verification
Working directly with semiconductor foundries throughout fabrication
Supporting thermal analysis, reliability assessments and device validation




Producing test specifications and characterising devices using RF probe stations and laboratory equipment
Contributing to technical reviews and supporting less experienced engineers
What they are looking for
Our client is looking for someone with strong commercial MMIC design experience and a track record of taking devices from concept through fabrication and verification.
You should have:
Industrial experience designing MMICs within a semiconductor environment
Strong experience with RF amplifiers, LNAs or frequency-conversion circuits
Experience using GaAs and/or GaN HEMT technologies
Hands-on RF measurement and device characterisation capability
A good understanding of microwave and millimetre-wave communication systems
Experience with WIN Semiconductor processes, products above 37GHz or mentoring other engineers would be useful, but is not essential.
