AI in this role
Define and implement DFT architecture, ATPG flows, and silicon bring-up for high-performance AI inference RDU chips.
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
