About the Role

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. Our novel wafer-scale architecture provides the AI compute power of dozens of GPUs on a single chip, with the programming simplicity of a single device. This approach allows Cerebras to deliver industry-leading training and inference speeds and empowers machine learning users to effortlessly run large-scale ML applications, without the hassle of managing hundreds of GPUs or TPUs.  

Cerebras' current customers include top model labs, global enterprises, and cutting-edge AI-native startups. OpenAI recently announced a multi-year partnership with Cerebras, to deploy 750 megawatts of scale, transforming key workloads with ultra high-speed inference. 

Thanks to the groundbreaking wafer-scale architecture, Cerebras Inference offers the fastest Generative AI inference solution in the world, over 10 times faster than GPU-based hyperscale cloud inference services. This order of magnitude increase in speed is transforming the user experience of AI applications, unlocking real-time iteration and increasing intelligence via additional agentic computation.

The Role: Senior Yield Enhancement Engineer 

We are seeking a highly experienced Senior VLSI Product and Test Engineer with 7+ years of relevant experience in Semiconductor Testing/Failure Analysis/Yield Enhancement. The successful candidate will look at ATE datalogs, understand the defects in detail, disposition wafers based on ATE data and drive FA/Yield enhancement using physical/optical inspection techniques used in FA. 

Suitable candidate will have depth in testing, characterization of silicon defects, failure modes, and experience delivering end-to-end solutions working closely with teams across chip design, fabrication, validation, production, and manufacturing. 

Key Responsibilities  

  • Analyze ATE data logs, Shmoo plots, parametric characterization data, and spatial wafer defect patterns. 
  • Develop failure analysis tools using optical, photo emission, and laser-based defect localization techniques specific to Cerebras hardware. 
  • Develop and execute FIB (Focused Ion Beam) edit plans for Silicon root cause validation. 
  • Communicating with OSATs and Fab to drive production testing in HVM environment. 
  • Understand DFT strategies including hierarchical scan chains, distributed BIST, SRAM test methodologies, and perform diagnosis on ATE data. 
  • Collaborate closely with DFT engineers, silicon architects, designers, performance teams, and software engineers to enhance overall testability and yield 
  • Refine test programs across di/dt behavior, voltage-frequency characterization space, current limits, and thermal constraints based on ATE logs and disposition learnings.
