Principal DFT Engineer
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
Your responsibilities will include:
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.
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
