Silicon Product & Test Engineer

Role overview This role leads post-silicon productization for advanced-node bitcoin mining ASICs, spanning everything from first-silicon bring-up through high-volume manufacturing. The position is deeply cross-functional, sitting at the intersection of silicon design, automated test engineering, systems, reliability, foundry, and outsourced assembly partners. The ideal candidate is hands-on, data-driven, comfortable operating in ambiguity, and excited about scaling complex hardware products in a fast-moving environment.

Responsibilities - Drive 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 targeting power, performance, yield, quality, and DPPM - Build, 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 - Analyze silicon data across CP, FT, bench, and system platforms to improve correlation and optimize system-level performance - Lead DOE planning, execution, and analysis for silicon characterization, yield optimization, and process tuning - Collaborate with system and hardware engineers on ASIC binning methodologies and system optimization strategies - Engage with foundry, OSAT, and external vendors to support bring-up, qualification, yield improvement, and manufacturing execution - Develop KPIs and dashboards tracking 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, final test, qualification, and high-volume manufacturing - Experience with silicon bring-up, characterization, yield analysis, and product qualification for advanced-node ASICs or SoCs - Hands-on experience with ATE platforms such as Advantest 93K or Chroma - Strong statistical data analysis and debugging skills using tools like JMP, Python, or comparable frameworks - Demonstrated ability to collaborate across design, systems, firmware, reliability, manufacturing, foundry, and OSAT teams - Comfort operating in ambiguous, fast-moving environments with a high degree of ownership

Nice to have - Experience with near-threshold operation or low-voltage optimization - Familiarity with high-performance computing, AI, networking, or bitcoin mining ASICs - Understanding of semiconductor device physics, SPICE fundamentals, and FinFET technologies - System-level characterization and correlation across ATE, bench, and deployed systems - Scripting and automation experience using Python, Perl, or TCL - Verbal fluency in Mandarin

Benefits and work setup - Remote work available - Medical insurance, flexible time off, retirement savings plans, and modern family planning benefits - Reasonable accommodations available throughout the hiring process
