Product Engineer, Silicon Validation

Job Summary

We are seeking an experienced Product Engineer to lead silicon validation, test program

development, and productization for our large-format AI accelerator chips. In this role, you will develop and execute test strategies from first silicon through high-volume manufacturing, partnering with cross-functional teams and external vendors to ensure production quality and cost targets. This role is critical to achieving first-pass silicon success and seamless NPI-to-HVM transitions.

Key Responsibilities

• Planning and executing comprehensive silicon characterization from first silicon through production release, including voltage-frequency-temperature characterization, corner testing, guard band determination, and production limit setting

• Lead test cost optimization efforts while maintaining quality standards

• Architect test flows to balance test time, coverage, and yield learning objectives for complex AI accelerator designs

• Drive systematic yield improvement initiatives through data-driven root cause analysis using statistical tools and methods

• Establish and track key quality metrics including DPPM and test escapes

• Perform die/package level bring-ups, troubleshoot failure modes, and resolve issues by collaborating with design, system validation, and operations teams

• Support OSAT bring-up, manage ATE/SLT manufacturing test program releases, and drive toward aggressive test cost goals

• Productize test programs and methodologies for seamless transition from engineering to high-volume manufacturing

• Analyze field return data and system-level failures to identify test coverage gaps and implement improved screening methods

• Drive ATE-system correlation activities to ensure test program accuracy and validate performance against system specs

• Manage relationships with test vendors, OSAT partners, and foundry partners

You may be a good fit if you have (Must-have qualifications)

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field

• 5-10+ years of hands-on experience in silicon validation, product engineering, and ATE test development for advanced node semiconductors

• Proven track record in yield optimization and DPPM reduction with quantifiable results

• Experience with silicon characterization methodologies including Fmax/Vmin characterization and power/thermal validation

• High-volume manufacturing test experience with demonstrated production scale results

• Proficiency in yield and fail pareto analysis using JMP, Exensio, DataPower, or OptimalPlus

• Strong understanding of test program debugging, failure analysis correlation, and yield enhancement techniques

Strong candidates may also have experience with (Nice-to-have qualifications)

• Experience developing and optimizing ATE test programs for wafer sort and final test on

  Advantest V93K platforms

• Experience managing wafer sort and final test across multiple advanced process nodes

• GPU, HPC, or AI accelerator chip testing background with production scale results

• HBM or high-speed memory interface testing and characterization experience

• Leading NPI through high-volume production with multi-vendor qualification across multiple OSAT sites

• Driving significant cost reduction initiatives

• Multi-site parallel testing strategies and test time optimization for large-format dies

• Scripting and automation skills (Python, Perl, TCL) for test data analysis and workflow automation

• Cross-functional leadership in silicon bring-up and manufacturing ramp
