Plessey is seeking a Principal Device Physicist to join its Device Engineering Team. This is a key role focusing on the development of measurement and modelling techniques applied to MQW micro-LED structures & advanced optical device development. The successful candidate will have substantial experience in the understanding of semiconductor devices and will be able to support and coach less experienced engineers in the team, taking a central role in developing new and applying existing measurement and modelling techniques to help develop new technologies.
Responsibilities
* Developing novel measurement methods for QW micro-LED structures
* Working in close collaboration with the Process Development and Process Architecture teams
* Identifying reasons for and solutions to performance limiting behaviour
* Developing and introducing new techniques to help characterise and understand the operation of our micro-LED structures & optical computing technologies
* Liaise with research institutions such as universities and government laboratories with a view to commissioning work outside of the scope that is possible within Plessey
* Produce clear and concise reports for dissemination of results among the engineering community
Qualifications
* Ph.D or MSc in Physics, Electronics or other suitable discipline
* Strong knowledge of semiconductor device physics and optoelectronic principles
* Hands‑on experience with optical and electrical characterization techniques for LEDs or photonic devices
* Substantial experience in semiconductor measurement and modelling
* Substantial industry experience in the measuring and modelling of semiconductor devices with knowledge of QW LED structures
* Strong analytical and problem‑solving skills
* Excellent written and verbal communication skills
* Ability to work collaboratively in a multidisciplinary team
Advantage
* Experience with high‑density MicroLED arrays, photonic integrated circuits, or optical computing devices
* Knowledge of ultrafast device characterisation, optical modulation, and reliability testing
* Understanding of quantum or nonlinear photonic effects relevant to optical computing
