The Role

We are looking for a Product & Test Engineer to drive post-silicon productization of our bitcoin mining ASICs from silicon bring-up through high-volume manufacturing. This role spans silicon characterization yield optimization test strategy development correlation across multiple platforms and system-level performance optimization.

This is a highly cross-functional role working across ASIC Design ATE Bench Systems Reliability Foundry and OSAT partners. The ideal candidate is hands-on data-driven comfortable operating in ambiguity and excited about building and scaling complex hardware products in a fast-moving environment.

You Will

• 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.

You Have

• Bachelors or Masters degree in Electrical Engineering Computer Engineering or a related field.
• 510 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.
• 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 Python or similar analysis frameworks.
• Experience with DOE planning silicon correlation and yield optimization methodologies.
• Experience collaborating cross-functionally across Design Systems Firmware Reliability Manufacturing Foundry and OSAT teams.
• Strong problem-solving skills with the ability to independently drive technical issues to closure.
• Comfortable operating in ambiguous fast-moving environments with a high degree of ownership.

Nice to Have

• 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 is a plus.
