SAW Filter Designer

Soitec is a listed company on the SBF 120 index and operates at the upstream end of the microelectronics value chain. Our innovative semiconductor materials are essential to the operation of smartphones and the deployment of 5G. They also offer numerous opportunities for connected automobiles, electric and autonomous vehicles, and embedded intelligence in connected objects. 

This position gives us an incredible responsibility, which inspires us every day: to enable the massive adoption of technological innovations while considerably limiting their environmental impact, in a spirit of responsible innovation and sustainable development.

The position is based in Besançon, in our premises within TEMIS Innovation. 

The team, made up of around ten employees and originating from the company frec|n|sys acquired in 2017, specializes in the design, modeling, characterization and manufacturing of small series of elastic wave components. 

His expertise is particularly involved in supporting the development of innovative substrates using piezoelectric materials. These substrates are currently used to manufacture elastic wave components such as radiofrequency band filters.

Reporting to the Design Manager, the Designer plays a key role in the creation and optimization of elastic wave devices.

The main missions are as follows:

• Design of elastic wave devices: Development of new devices while respecting current quality standards and conversion of designs into production files (GDS). Support to the Design Manager.
• Exploration of innovative concepts and designs: Investigation of new filter architectures and proposal of disruptive developments in interaction with the development teams.
• Monitoring development until compliance validation: Analysis of measurements compared to design results, establishment of the compliance matrix, and contribution to the continuous improvement of models.
• Technological monitoring and scientific communications: Proposal of patent filings, writing of scientific articles and participation in conferences to increase the scientific influence of the company.
