IC Layout Engineer - MMIC

MMIC Layout Engineer | GaN / Compound Semiconductors | SC-Eligible North East England | On-site – 1–2 days home working | Competitive + Bonus + Relocation 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
