Principal DFT Engineer

About the role

SambaNova is looking for a talented and motivated Principal Design for Test (DFT) Engineer to help build state-of-the-art RDU chips for machine learning and artificial intelligence. We are seeking a highly hands-on engineer 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.
• 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.

Requirements

• B.S. in computer science, computer engineering, or related field.
• 10+ years of 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.
