The Role With Proto, we're building hardware and software that will help decentralize bitcoin mining, promote new and innovative use cases for bitcoin mining, and drive a major new business for Block. We're looking for a Post-Silicon Lead who will drive productization of our bitcoin mining chips.
You will: - Bring Proto silicon from first samples to mass production
- Develop and implement test strategies that lead to better performance and faster delivery
- Collect and analyze both wafer-level and bench test data and collaborate with data scientists to characterize and optimize silicon performance
- Work with foundry to identify potential device parameter changes to enable efficient low-voltage operation and maximize performance
- Collaborate with hardware system engineers to determine appropriate binning strategies and to design systems that get the most out of the individual and collective ASIC performance
- Collaborate with ASIC design engineers to improve test capabilities at a silicon level and to inform what device improvements could improve circuit performance and energy efficiency
- Lead a small team of test engineers to deliver on the responsibilities in this job description
You have: - 10 + years of post-education experience in fab or fabless environments, technology definition and bring-up, device/process architecture, and NPI
- Experience with near-threshold operation (and bitcoin mining specifically is a huge plus)
- Experience with CP, FT, and bench test data collection and analysis - and ability and willingness to get your hands dirty on all of these activities
- Bias to action - if it needs doing, you're already working on it, and with the right level of scrappiness for the task
- An effective technical leadership approach and ability to inspire and develop great engineers
- Deep understanding of SPICE fundamentals, simulation methodologies, and BSIM FinFET models
