Radio Frequency Engineer

Overview

PDK 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 a PDK Engineer to take ownership and strengthen the link between fabrication, device physics, and MMIC design. You'd be joining a leading compound semiconductor company expanding its GaN technology platforms.

It's a hands-on role in a manufacturing-led environment, where process maturity is still evolving and PDKs are tightly coupled to yield, reliability, and RF performance, not just compliance.

• Develop, release, and maintain PDKs for GaN and compound semiconductor MMIC processes
• Own and evolve DRC and LVS decks
• Own and evolve parameterised cells (PCells)
• Translate process and device constraints (thermal, breakdown, trapping, reliability) into practical design rules
• Work closely with Process and Device Engineering to reflect real wafer behaviour in PDK releases
• Support designers with layout and model related issues impacting RF and power performance
• Maintain documentation, version control, and formal release flows
• Support new process introductions and technology qualification activity
• Track process changes and ensure downstream design flows remain valid
• Automate checks, flows, and validation using scripting where appropriate

• Degree in Electronics, Physics, Materials, or similar
• Experience working with EDA layout environments and verification flows
• Scripting skills (Python, SKILL, Tcl, or similar)
• Understanding of semiconductor fabrication and design-for-manufacture principles
• Comfortable working with evolving processes and imperfect datasets
• Exposure to RF, MMIC, GaN, or other III–V technologies is strongly beneficial
• Experience with silicon PDKs is relevant, but candidates must be open to more process-driven design rules

• Competitive salary with relocation support
• Long-term investment strategy in GaN and RF technology platforms
• High levels of technical ownership and impact
• Good progression within a scaling company
