About the role
Responsibilities
- Drive post-silicon bring-up, characterization, qualification, and productization activities from first silicon through mass production
- Develop and optimize wafer sort (CP) and final test (FT) screening strategies to improve power, performance, yield, quality, and DPPM
- Develop, debug, and maintain ATE test programs and screening methodologies for advanced-node ASICs
- Define and execute characterization plans across process, voltage, and temperature (PVT) conditions
- Perform silicon data analysis across CP, FT, Bench, and System platforms to improve correlation and optimize system-level performance
- Drive DOE planning, execution, and analysis for silicon characterization, yield optimization, and process tuning
- Collaborate with system and hardware engineers to develop effective ASIC binning methodologies and system optimization strategies
- Define and support ATE hardware requirements including probe cards, sockets, and load boards
- Analyze wafer-level and package-level parametric and functional data to identify trends and root-cause failures
- Engage with foundry, OSAT, and external vendors to support bring-up, qualification, and manufacturing execution
- Develop KPIs and dashboards to track power, performance, process variation, yield, and product quality metrics
Requirements
- Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field
- 5–10 years of experience in Product Engineering, Test Engineering, Silicon Validation, or Post-Silicon Engineering
- Strong understanding of semiconductor manufacturing flows including wafer sort (CP) and final test (FT)
- Experience with silicon bring-up, characterization, yield analysis, and product qualification for advanced-node ASICs or SoCs
- Experience with ATE platforms such as Advantest 93K or Chroma
- Experience developing or debugging ATE test programs and production screening methodologies
- Strong statistical data analysis and debugging skills using tools such as JMP or Python
- Experience with DOE planning, silicon correlation, and yield optimization methodologies
- Experience collaborating cross-functionally across Design, Systems, Firmware, Reliability, and Manufacturing teams
Preferred Qualifications
- Experience with near-threshold operation or low-voltage optimization
- Experience with high-performance computing, AI, networking, or bitcoin mining ASICs
- Understanding of semiconductor device physics, SPICE fundamentals, and FinFET technologies
- Experience with system-level characterization and correlation across ATE, Bench, and deployed systems
- Experience with scripting or automation using Python, Perl, or TCL
- Verbal fluency in Mandarin
