System Validation and Signal Integrity Engineer

Overview

We are looking for an experienced engineer to lead Silicon Validation and Signal Integrity analysis for our next-generation high-speed interconnect products. In this role, you will bridge the gap between theory and reality, driving simulation strategies for 112G/224G systems and executing rigorous post-silicon characterization for DSP and Optical PHYs.

• Post-Silicon Leadership:
  Lead the post-silicon validation and electrical characterization of PHY layer chips, specifically for DSP and Optical products.
• Test Development:
  Define validation plans and develop automated test benches for high-speed I/O testing.
• Interoperability:
  Conduct interoperability testing and validate Broadcom PLP products with Broadcom Tomahawk Switches.
• Debugging:
  Troubleshooting and debug complex hardware issues related to power integrity, signal integrity, and clocking on reference platforms.
• Signal Integrity Analysis, Simulation & Modeling:
  High-Speed Link Design:
  Drive comprehensive SI support for high-data-rate Ser Des applications (up to 112
  
  Gbps NRZ and 224G PAM4), ensuring channel compliance and performance optimization.
• Advanced Simulation:
  Execute schematic and channel simulations using Keysight ADS. Utilize bit-by-bit and statistical simulators to analyze Ser Des link performance, applying numerical analysis and electromagnetic field theory to optimize designs.
• Channel Characterization:
  Perform detailed channel analysis including Insertion Loss (IL), Return Loss (RL), crosstalk, and Time Domain Transmission (TDT).
• Noise & Interference:
  Execute advanced noise analysis, specifically calculating EIPS (Effective Inter-Pair Skew/Signal) and EICN (Effective In-Channel Noise) to ensure robust link margins.
• Phase Noise & Jitter:
  Conduct phase noise analysis for PLLs, reference clocks, and Ser Des TX-RX links, alongside jitter sensitivity measurements and BER analysis for Ser Des IP.
• Correlation:
  Lead measurement-simulation correlation initiatives. Partner with package, PCB, and silicon design teams to validate design accuracy and refine simulation models based on lab data.

Education & Experience:

• BS with 8+ years of experience, MS with 6+ years of experience, or PhD with 3+ years of experience in Electrical Engineering, Physics, or a related field.

Technical Expertise:

• Theory:
  Deep understanding of transmission line theory, S-parameters, high-speed serial protocols (Ethernet, PCIe, PAM4 signaling), and electromagnetic field theory.
• Simulation Tools:
  Hands-on experience with SI simulation tools (e.g., Keysight ADS, MATLAB, Mentor Graphics Hyper Lynx).
• Lab Equipment:
  Proficiency with Vector Network Analyzers (VNA) up to 50GHz+, TDRs, high-bandwidth Oscilloscopes, and BERTs.
• Scripting & Automation:
  Strong experience with MATLAB, Python, or C/C++ for data analysis and lab automation.
• Key
  
  Competencies:
  
  Ability to work in both time and frequency domains.
• Proven track record of bridging pre-silicon design and post-silicon validation.
• Strong analytical skills for troubleshooting complex link topology issues.

The annual base salary range for this position is $108,000 - $172,800. This position is also eligible for a discretionary annual bonus in accordance with relevant plan documents, and equity in accordance with equity plan documents and equity award agreements.
