Silicon Product and Test Engineer
About this role
Proto seeks a Product & Test Engineer to lead post-silicon productization of bitcoin mining ASICs, managing silicon bring-up through mass production. This cross-functional role involves silicon characterization, test strategy development, yield optimization, and system-level performance tuning for advanced-node chips.
What you'll do
- Drive post-silicon bring-up, characterization, and productization from first silicon through high-volume manufacturing
- Develop and optimize wafer sort and final test screening strategies to improve yield, power, performance, and quality metrics
- Create and maintain ATE test programs and debug screening methodologies for advanced-node ASICs
- Execute characterization plans across process, voltage, and temperature conditions with DOE planning and analysis
- Analyze silicon data across multiple platforms to improve correlation and identify trends, failures, and root causes
- Collaborate with foundry, OSAT, and internal teams on ASIC binning, system optimization, and manufacturing execution
What they're looking for
- Post-silicon validation and silicon bring-up
- ATE platform experience (Advantest 93K, Chroma)
- Statistical data analysis (JMP, Python)
- Wafer sort and final test methodology development
- DOE planning and yield optimization
- Design of Experiments and silicon correlation
- Cross-functional collaboration across design, systems, and manufacturing
- Problem-solving and independent technical ownership
