Job Description

This role involves designing and implementing advanced Design for Testing (DFT) methodologies for AI/ML hardware acceleration, specifically Google's Tensor Processing Units (TPUs). Responsibilities include defining silicon test strategies, implementing DFT specifications for next-generation SoCs, inserting and verifying DFT logic, and collaborating with test engineers on post-silicon debug. The engineer will contribute to reducing test costs, increasing production quality, and enhancing yield. The position requires expertise in DFT architecture, EDA tools, and ASIC flows, with a focus on TPU architecture and its integration within AI/ML systems.

Must have:

Bachelor's degree in Electrical Engineering or related field
3+ years experience in DFT specification, architecture, and insertion
Experience with EDA test tools (Spyglass, Tessent)
ASIC DFT synthesis, STA, simulation, and verification
Develop DFT strategy and architecture
Insert DFT logic and MBIST logic
Document DFT architecture and test sequences

Good to have:

Master's degree in Electrical Engineering
IP integration experience (memories, test controllers, TAP, MBIST)
SoC cycle experience (silicon bring-up, debug)
Fault modeling experience
Experience working with ATE engineers

Minimum qualifications:

Bachelor's degree in Electrical Engineering or a related field, or equivalent practical experience.
3 years of experience in DFT specification definition architecture and insertion.
Experience using electronic design automation (EDA) test tools (e.g., Spyglass, Tessent).
Experience with ASIC DFT synthesis, STA, simulation, and verification flow.

Preferred qualifications:

Master's degree in Electrical Engineering.
Experience in IP integration (e.g., memories, test controllers, TAP, and MBIST).
Experience in SoC cycles, including silicon bring-up and silicon debug activities.
Experience in fault modeling.
Experience working with ATE engineers (e.g., silicon bring-up, patterns generation, debug, validation on automatic test equipment, and debug of silicon issues, etc.).

About the job

In this role, you’ll work to shape the future of AI/ML hardware acceleration. You will have an opportunity to drive cutting-edge TPU (Tensor Processing Unit) technology that powers Google's most demanding AI/ML applications. You’ll be part of a diverse team that pushes boundaries, developing custom silicon solutions that power the future of Google's TPU. You'll contribute to the innovation behind products loved by millions worldwide, and leverage your design and verification expertise to verify complex digital designs, with a specific focus on TPU architecture and its integration within AI/ML-driven systems.

In this role, you will be responsible for defining, implementing, and deploying advanced Design for Testing (DFT) methodologies for digital, mixed-signal chips, or IPs. You will define silicon test strategies, Implement, and create DFT specifications for next generation SoCs while working with the DFT Organization. You will design, insert, and verify the DFT logic, and will prepare for post-silicon and co-work/debug with test engineers. You will be responsible for reducing test cost, increasing production quality, and enhancing yield.
