Senior Validation & SI Correlation Engineer

The role

This person will drive correlation between SI simulations and physical lab measurements. They will perform system-level electrical validation and develop Python-based automation scripts for data collection.

What you will do

• Drive correlation between pre- and post-layout SI simulations and physical lab measurements.
• Quantify simulation-vs-measurement gaps for PCIe Gen5/6, DDR5, and 112G/224G Ethernet.
• Develop and refine EM models for PCB discontinuities, high-speed connectors, and vias.
• Investigate discrepancies caused by manufacturing tolerances, material properties, or de-embedding inaccuracies.
• Lead validation of housekeeping and control buses including I2C, SPI, eSPI, UART, and SMBus.
• Validate complex power-on/off sequences and correlate VR control loop simulations with physical measurements.
• Ensure reliable operation of sideband signals, reset logic, and BMC hardware interfaces.
• Work cross-functionally to resolve system-hang and link-training failures.
• Author comprehensive Hardware Validation Plans.
• Build Python-based automation scripts to drive data collection from VNAs, BERTs, and oscilloscopes.

Required qualifications

• B.S. or M.S. in Electrical Engineering
• 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
• 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)
• Strong fundamentals in digital circuit design, debug, and computer architecture
• Familiarity with the unique power and thermal challenges of high-density AI clusters
• Programming fluency in Python or equivalent scripting languages (Perl, Shell)
• PCIE Gen5/6 and 100g Ethernet Expertise

Nice to have

• 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
• Ability to build end-to-end automated test frameworks in Python or TCL, integrating lab equipment with Pandas/NumPy

Benefits

• Base salary plus equity
• 95% premium coverage for employee medical insurance
• 77% premium coverage for dependents
• Health Savings Account (HSA) with employer contribution
• Dental, Vision, Short/Long term Disability, Basic Life, Voluntary Life, and AD&D insurance plans
• Flexible Spending Account (FSA) options like Health Care, Limited Purpose, and Dependent Care
• Headspace subscription
• Gympass+ membership
• One Medical membership
• Counseling services with an Employee Assistance Program
