IC Layout Engineer - MMIC in Sunderland

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
