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, root-cause failures, and drive corrective actions.
  • Engage with foundry, OSAT, and external vendors to support bring-up, qualification, yield improvement, 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 in fabless or semiconductor environments.
  • Strong understanding of semiconductor manufacturing flows including wafer sort (CP), final test (FT), qualification, and high-volume manufacturing.
