Job summary

SambaNova Systems is seeking a Principal Design for Test (DFT) Engineer to help build state-of-the-art RDU chips for ML/AI. You will own DFT architecture, verification, ATPG, MBIST and silicon bring-up for high-performance chips.

Responsibilities include defining DFT for large SoCs, maintaining ATPG flows, automating DFT tasks, and integrating JTAG/IJTAG interfaces for test access. Collaboration with STA and PD teams is required to meet timing closure and yield goals.

Qualifications

• BS in CS/CE or related field; 10+ years experience.
• Deep knowledge of scan insertion, ATPG, MBIST, JTAG.
• STA constraints and DFT timing experience preferred.

Responsibilities

• Define & implement block-level and SoC-level DFT architecture for large, hierarchical SoCs.
• Develop and maintain ATPG flows for stuck-at, at-speed and advanced fault models.
• Develop scripts and automation for DFT insertion, ATPG, coverage analysis, pattern generation, and debug.
• Develop and maintain JTAG, IEEE 1500, and IEEE 1687/IJTAG infrastructure for internal test and debug access.
• Generate production-quality ATPG and MBIST patterns and support deployment to ATE.
• Work closely with STA and Physical Design teams on DFT timing closure.
• Support silicon diagnosis, failure localization, yield analysis, and manufacturing test optimization.

Job description

The era of pervasive AI has arrived. In this era, organizations will use generative AI to unlock hidden value in their data, accelerate processes, reduce costs, drive efficiency and innovation to fundamentally transform their businesses and operations at scale. SambaNova Suite™ is the first full-stack, generative AI platform, from chip to model, optimized for enterprise and government organizations. Powered by the intelligent SN40L chip, the SambaNova Suite is a fully integrated platform, delivered on-premises or in the cloud, combined with state-of-the‑art open-source models that can be easily and securely fine‑tuned using customer data for greater accuracy. Once adapted with customer data, customers retain model ownership in perpetuity, so they can turn generative AI into one of their most valuable assets.

About The Role

Sambanova is looking for a talented and motivated Principal Design for Test (DFT) Engineer to help us build state‑of‑the‑art RDU chips for machine learning and artificial intelligence. We are looking for a highly hands‑on engineer who will be responsible for DFT architecture and implementation, verification, ATPG, MBIST and silicon bring‑up for complex high‑performance chips.

Responsibilities

• Define & implement block-level and SoC-level DFT architecture for large, hierarchical SoCs
• Develop and maintain ATPG flows for stuck‑at, at‑speed and advanced fault models.
• Develop scripts and automation for DFT insertion, ATPG, coverage analysis, pattern generation, and debug.

• Support silicon diagnosis, failure localization, yield analysis, and manufacturing test optimization.

Required Qualifications

• B.S. in computer science, computer engineering, or related field
• 10+ years relevant industry experience
• Deep understanding of scan insertion, scan compression, ATPG, MBIST, JTAG, and hierarchical DFT
• Hands‑on experience with Siemens Tessent tool flow (preferred) or equivalent industry standard DFT tools
• Familiarity with cell‑aware ATPG, small‑delay defects, IEEE 1500, IEEE 1687/IJTAG, and low‑power DFT is highly desirable
• Strong understanding of advanced ATPG, silicon diagnosis, and failure localization methodologies
• Experience with STA constraints & analysis for DFT modes & SDF simulations
• Working knowledge of Verilog/System‑Verilog simulators & waveform debugging

Preferred Qualifications

• Experience with ATE pattern deployment and silicon bring‑up
• Experience with multi‑die/chiplet DFT, known‑good‑die test, or die‑to‑die interface testing
• Experience with large compute, AI accelerator, or HPC SoCs
