-Evaluate next-generation flash memory, with a focus on optimizing cell array operating voltages and timing, as well as reliability evaluation
-Contribute to manufacturing process improvements based on cell array characterization results
-Perform statistical analysis of variability in mass production cell array characteristics
-Develop test programs for cell array characterization
-Develop screening tests to improve early failure (DPPM) rates
-Conduct failure analysis using electrical methods
-Collaborate with overseas sites on the above activities 
-Lead product steering toward commercialization

CMOS Device:
-Perform electrical evaluation and analysis of next-generation CMOS (transistors and passive devices)
-Design TEGs and define design rules for next-generation  CMOS development
-Improve CMOS characteristics toward mass production (reliability and variability improvements, etc.)
-Conduct electrical evaluation and statistical data analysis (e.g., using Spotfire) to improve yield related to CMOS
-Develop screening and stress tests to improve DPPM (customer and field failure rate)
-Serve as an interface between backend sites (overseas) and frontend fabs (domestic)

Required:
- Multiple years of experience in semiconductor device engineering, failure analysis, or testing
- Proficiency in technical communication and report writing in English

Preferred:
- Strong knowledge and experience in programming languages such as C, C++, Python, and Java
- Experience in large-scale data analysis
- Work experience with NAND flash or DRAM devices
