Wolviston Management Services are delighted to be supporting our client in the recruitment of a talented Device Modelling & PDK Engineer to join their specialist engineering team.

Our client operates within the highly technical semiconductor industry, developing advanced microwave GaN and GaAs device technologies for demanding RF and microwave applications.

This is an excellent opportunity for an experienced engineer with a strong background in semiconductor device characterisation, RF/microwave testing and compact device modelling to contribute to the development of advanced Process Design Kits (PDKs).

Working alongside experienced design, development and engineering teams, you will play a key role in ensuring device models are accurate, reliable and optimised to support customer design requirements.

As Device Modelling & PDK Engineer, you will be responsible for the characterisation, modelling and validation of compound semiconductor devices, supporting the development and continuous improvement of MMIC Process Design Kits.

You will work closely with device engineers, designers and technical teams to ensure models accurately represent device performance and provide customers with effective design solutions.

• Performing and coordinating RF/microwave device characterisation to support device model development and validation.
• Developing compact device models for GaN and GaAs semiconductor technologies.
• Carrying out DC, pulsed I-V, noise, small-signal and large-signal microwave performance testing.
• Generating and validating small-signal and large-signal device models and passive component models.
• Supporting the development, enhancement and maintenance of MMIC Process Design Kits (PDKs).
• Providing technical support to customers using PDKs and responding to design-related queries.
• Working closely with design engineers to understand requirements, resolve technical challenges and incorporate feedback.
• Supporting new semiconductor process development through device assessment and characterisation.
• Producing detailed technical reports, documentation and supporting engineering information.
• Providing specialist device characterisation expertise to development projects and operational teams.
• Keeping up to date with emerging device modelling and characterisation techniques to support continuous improvement and technological competitiveness.

We are keen to hear from technically capable engineers with experience in semiconductor device characterisation and RF/microwave technologies.

• A degree in Electronic Engineering, Physics or a closely related discipline.
• Practical experience in DC and RF/microwave semiconductor device characterisation.
• A strong understanding of RF/microwave device physics and semiconductor device behaviour.
• Experience performing RF/microwave testing and interpreting device performance data.
• A sound understanding of small-signal and large-signal circuit theory and device equivalent circuits.
• Knowledge and appreciation of compact semiconductor device modelling.
• Programming experience, particularly within testing or engineering environments.
• Strong analytical and problem-solving abilities with excellent attention to detail.
• The ability to work independently while contributing effectively within a multidisciplinary engineering team.

• Experience working with compound semiconductor technologies, particularly GaN or GaAs.
• RF on-wafer testing and semiconductor device measurement techniques.
• Compact device model extraction and validation.
• Knowledge…
