- Investigate transistor- and diode-level degradation mechanisms, develop acceleration methodologies, and establish qualification plans to assess long-term device reliability.
- Apply advanced statistical and data analysis techniques to identify reliability risks, understand failure mechanisms, and guide technology development decisions.
- Build and expand device reliability characterization infrastructure, enabling rapid assessment of new technologies while supporting future growth in capability and test capacity.
- Partner with technology development, product engineering, process integration, and manufacturing teams to translate reliability data into action that drives product success.
- Communicate results to technical and business stakeholders, influencing technology roadmaps and qualification decisions.
What you'll need
- B.S. in Electrical Engineering, Materials Science, Chemical Engineering, Physics, or a related technical field (or equivalent industry experience).
- 8+ years of proven experience in semiconductor device reliability.
- Strong understanding of transistor and diode operation, including device characteristics, performance tradeoffs, and failure mechanisms.
- Solid foundation in semiconductor device physics and the principles governing device behavior and reliability.
- Experience developing or interpreting reliability qualification methodologies for semiconductor devices.
- Familiarity with electrical characterization and reliability test equipment used for semiconductor devices and circuits.
- Strong background in probability, statistics, and data analysis.
- Analytical and problem-solving skills, including root-cause analysis and failure mechanism investigation.
Nice to have
- Knowledge of III-V semiconductor technologies including InP, GaAs, or related compound semiconductor platforms.
- Experience with high-frequency device technologies, including design, fabrication, process integration, characterization, or reliability evaluation.
- Hands-on experience applying Statistical Process Control (SPC) and Design of Experiments (DOE) methodologies.
