Senior Characterization & Verification Engineer (w/m/d)

Job Title

Senior Characterization & Verification Engineer (w/m/d)

Role Summary

Join the Power Semiconductor R&D team to lead characterization and verification of power semiconductor devices (SiC Schottky diodes, SiC MOSFETs, Si MOSFETs, IGBTs). Drive automation, test-system standardization, and global harmonization of measurement procedures across lab sites.

Experience Level

Senior — minimum 5 years of professional experience in semiconductor device characterization or a closely related field.

Responsibilities

The role owns device characterization and verification activities and the development of automated, reproducible test systems.

• Lead and execute electrical and thermal characterization and verification campaigns to achieve full functional coverage.
• Collaborate with design owners and product managers to develop test specifications and verification plans.
• Design, implement, maintain, and optimize automated test setups and measurement systems.
• Analyze measurement data and produce technical reports for datasheets and internal design documentation.
• Conduct design verification reviews aligned with applicable international standards.
• Drive global harmonization of Standard Operating Procedures (SOPs) across characterization labs.
• Identify and implement best practices in metrology, automation, and data analysis.
• Troubleshoot test failures, define corrective actions, and support their implementation.

Requirements

Must-have technical skills and experience; a few preferred capabilities are noted.

• At least 5 years of hands-on experience in semiconductor device characterization or equivalent role.
• Proven expertise in electrical characterization of power semiconductors across Si, SiC, and GaN technologies.
• Practical experience with test instruments: oscilloscopes, parameter analyzers, PXI systems.
• Experience with statistical data analysis and measurement-system evaluation.
• Strong understanding of measurement-circuit design, high-speed switching behavior, and thermal characterization methods.
• Knowledge of IEC 60747 and JEDEC standards, including thermal methods such as Rth/Zth analysis.
• Experience developing automated tests using Python, MATLAB, LabVIEW, C, C++ or C#.
• Experience in PCB design and development of test fixtures.
• Proven ability to work across global lab sites and lead cross-functional initiatives.
• Excellent communication and presentation skills; able to convey technical results clearly.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering, Physics, Semiconductor Technology or a comparable technical field.

Approximate annual gross salary: €80,000–€100,000 (final compensation depends on experience and qualifications).
