About the role

  • SambaNova Systems is redefining what's possible in AI infrastructure-and the hardware that powers it has to be flawless.
  • This is a high-impact, highly visible role that blends deep Signal Integrity (SI) expertise with rigorous system-level hardware validation.
  • You will work at the frontier of AI compute-validating PCIe Gen5/6, DDR5, and 112G/224G Ethernet interfaces on systems pushing the limits of what data center hardware can do.

Responsibilities

  • Drive the correlation between pre- and post-layout SI simulations and physical lab measurements, closing the loop between theory and hardware reality.
  • Develop and refine EM models for PCB discontinuities, high-speed connectors, and vias using Ansys HFSS, Cadence Sigrity, or equivalent tools.
  • Investigate discrepancies caused by manufacturing tolerances, material (Dk/Df), or de-embedding inaccuracies and drive them to resolution.
  • Lead validation of housekeeping and control buses-I2C, SPI, eSPI, UART, SMBus-ensuring protocol compliance and robust timing margins.
  • Validate complex power-on/off sequences and correlate VR control loop simulations with physical transient response and ripple measurements.
  • Build Python-based automation scripts to drive data collection from VNAs, BERTs, and oscilloscopes-accelerating validation throughput and repeatability.
  • Strong fundamentals in digital circuit design, debug, and computer architecture.
  • Ability to build end-to-end automated test frameworks in Python or TCL, integrating lab equipment with Pandas/NumPy for rapid correlation.

Requirements

  • 10+ years of experience in high-speed digital design or hardware validation within a data center, systems architecture, or server bring-up environment.
  • Expert-level proficiency in SI/EM tools: Ansys HFSS/SIwave, Cadence Sigrity/Allegro, or Keysight ADS.

Nice to have

  • B.S. or M.S. in Electrical Engineering (M.S. preferred).

Skills

  • Hands-on mastery of high-bandwidth real-time oscilloscopes, VNAs, and logic analyzers.
  • Deep knowledge of high-speed protocol physical layers (PCIe, IEEE 802.3) and low-speed control buses (I2C, SPI).
  • Familiarity with the unique power and thermal challenges of high-density AI clusters-including 48V power delivery and high di/dt transients.
  • Programming fluency in Python or equivalent scripting languages (Perl, Shell).
  • PCIE Gen5/6 and 100g Ethernet Expertise
  • M.S. or Ph.D. with emphasis in Electromagnetics, Computer Architecture, or Power Electronics.
  • Hands-on experience validating GPU/TPU modules or AI-specific interconnects such as NVLink or CXL.
  • Transaction- and link-layer expertise in PCIe Gen5/6 and DDR5-not just physical layer knowledge.
  • The era of pervasive AI has arrived.
  • SambaNova Suite™ is the first full-stack, generative AI platform, from chip to model, optimized for enterprise and government organizations.
