Company

Building open-economy products including Bitkey self-custody bitcoin wallets and hardware and software for decentralized bitcoin mining.

What you will do

• Drive post-silicon bring-up, characterization, qualification, and productization from first silicon through mass production.
• Develop and optimize wafer sort and final test screening strategies for power, performance, yield, quality, and DPPM.
• Develop, debug, and maintain ATE test programs and define characterization plans across process, voltage, and temperature conditions.
• Analyze data across CP, FT, bench, and system platforms to improve correlation, identify root causes, and optimize system-level performance.
• Plan and execute DOE studies for silicon characterization, yield optimization, and process tuning.
• Collaborate with ASIC Design, ATE, Systems, Reliability, Foundry, OSAT, and external vendors on binning, hardware requirements, qualification, and manufacturing execution.

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 wafer sort, final test, qualification, and high-volume semiconductor manufacturing.
• Experience with silicon bring-up, characterization, yield analysis, product qualification, and advanced-node ASICs or SoCs.
• Experience with Advantest 93K, Chroma, or comparable ATE platforms, including production test program development or debugging.
• Strong statistical analysis and debugging skills using JMP, Python, or similar tools, plus experience with DOE, silicon correlation, and yield optimization.

Nice to have
