Silicon Product and Test Engineer

About 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.

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.
• 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.

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.

Skills

• Verbal fluency in Mandarin is a plus.
