Senior Member of Technical Staff, SiC MOSFET Technology - Scottsdale, AZ, United States
Originally posted 19 August 2026 by the employer.
Support the development and qualification of SiC MOSFETs.
About the role
This role supports the development and qualification of silicon carbide (SiC) MOSFETs, working across teams to ensure new technologies meet automotive-grade reliability requirements. The position focuses on the reliability of SiC MOSFETs as they are deployed in advanced packages for customer requirements.
What you'll do
- Coordinate with the SiC Technology Development team to qualify new technology nodes in silicon carbide power devices.
- Identify key areas of reliability concern based on customer inputs and mission profiles.
- Collect inputs on key failures from internal stakeholders, customer feedback, and internal reliability testing.
- Develop reliability test method to quantify the impact of design/process changes on reliability in customer-relevant conditions.
- Co-develop with the backend Packaging Engineering team to enable qualifications across all package and module platforms.
- Prepare collateral to communicate reliability status/projections to internal teams and customers.
What you'll need
- B.S., M.S. or Ph.D. in Chemical Engineering, Electrical Engineering, Material Science or closely related discipline.
- 10+ years of experience in semiconductor development or manufacturing.
- 5+ years of experience in the development and qualification of discrete power components.
- Experience with process integration and reliability issues.
- Experience working with cross-functional engineering teams with matrixed responsibility for new product qualifications.
Nice to have
- Experience in silicon carbide.
