Senior Characterization & Verification Engineer

Job Title

Senior Characterization & Verification Engineer

Role Summary

As a Senior Characterization & Verification Engineer on the Power Semiconductor R&D team you will lead electrical and thermal characterization and verification of power semiconductor devices (SiC Schottky diodes, SiC-MOSFETs, Si-MOSFETs, IGBTs). You will drive automation and standardization of measurement systems across global labs and deliver data and reports used for product design, datasheets, and verification.

Estimated gross annual salary: approximately €80,000–€100,000.

Experience Level

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

Responsibilities

Lead and execute characterization and verification workstreams; collaborate with design and product teams; develop and automate test setups; analyze results and document findings.

• Plan and perform electrical and thermal characterization tests to ensure comprehensive functional coverage.
• Collaborate with design owners and product managers to develop test specifications and verification plans.
• Develop, maintain, and optimize automated test setups and measurement systems to improve efficiency and reproducibility.
• Analyze measurement data and produce technical reports for datasheets and internal design documentation.
• Conduct design-verification reviews aligned with international standards.
• Drive global harmonization of standard operating procedures (SOPs) across characterization laboratories.
• Identify and implement best practices in metrology, automation, and data analysis.
• Troubleshoot test failures, define corrective actions, and support their implementation.

Requirements

Core technical skills and hands-on experience required; additional skills are desirable.

• Must-have: Minimum 5 years' experience in characterization of semiconductor devices (power devices such as Si, SiC, GaN).
• Must-have: Practical experience with instruments such as oscilloscopes, parameter analyzers and PXI systems.
• Must-have: Experience developing automated tests and measurement control using Python, MATLAB, LabVIEW, C, C++ or C#.
• Must-have: Strong understanding of measurement-circuit design, high di/dt and dv/dt transient effects, and thermal characterization methods.
• Must-have: Experience with PCB design and development of test fixtures.
• Must-have: Experience working in a global laboratory environment with cross-site collaboration.
• Must-have: Strong communication and presentation skills; ability to lead cross-functional initiatives and drive process improvements.
• Nice-to-have: Familiarity with IEC 60747 and JEDEC standards, including thermal impedance (Rth/Zth) analysis.
• Nice-to-have: Experience in statistical data analysis and measurement-system evaluation.

Education Requirements

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