Job Description
MMIC Layout Engineer | GaN / Compound Semiconductors | SC-Eligible
North East England | On-site – | Competitive + Bonus + Relocation
**We are looking for people with electronics and CAD knowledge who are interested in moving into RF layout and design OR direct RF layout experience.**
This is a new position for an MMIC Layout Engineer to strengthen the link between circuit design, device physics, and manufacturing. You’d be joining a leading compound semiconductor company expanding its GaN technology platforms across RF and power applications.
It’s a hands-on role in a manufacturing-led environment, where layout decisions directly affect RF performance, thermal behaviour, yield, and long-term reliability.
The role
* Produce MMIC layouts for GaN and compound semiconductor processes from schematic and design intent
* Apply and feedback on PDK design rules driven by thermal, breakdown, and reliability limits
* Create arrayed die and full reticle layouts for mask manufacture
* Prepare and release mask data to fabrication partners
* Support design and mask reviews prior to fab release
* Maintain and update Process Control Monitor (PCM) and test structures
* Support technology development masks and experimental process splits
* Work closely with Device and Process Engineering on layout structures impacting RF performance and lifetime
* Track process updates and ensure layouts remain aligned to current manufacturing capability
Key knowledge and experience
* Degree in Electronics, Physics, or similar
* Strong CAD and physical layout experience
* Understanding of how layout impacts RF behaviour, breakdown, and thermal performance
* Familiarity with manufacturing release flows and documentation standards
* Comfortable working in detail-driven, production-facing environments
* Exposure to RF, MMIC, GaN, or other III–V technologies is strongly beneficial
* Strong silicon layout engineers with RF interest and willingness to learn compound processes will be considered
What’s on offer
* Competitive salary with relocation support
* Long-term investment strategy in GaN and RF technology platforms
* High levels of technical ownership and real product impact
* Good progression within a scaling company
