MMIC Layout Engineer GaN / Compound, Semiconductors

MMIC Layout Engineer | GaN / Compound Semiconductors 

Newcastle upon Tyne| On-site | 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.

Role overview:

• Produce MMIC layouts for GaN and compound semiconductor processes from schematic and design intent.
• Apply and provide 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.
