Principal DFT Engineer

SambaNova is a leader in next-generation AI infrastructure, delivering a full-stack inference platform for customers worldwide. At the core of SambaNova's technology is the RDU (Reconfigurable Dataflow Unit) — a chip built on a dataflow architecture rather than the traditional GPU model. Its decode performance is especially strong for agentic workloads like multi-turn agents, code generation, and long-running applications. RDUs are packaged into SambaRack, rack-scale hardware that lets customers deploy state-of-the-art models with better performance, greater energy efficiency, and faster time to value.

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
