    Description

    Senior Signal Integrity and Power Integrity (SI/PI) Engineer

    We're looking for a highly skilled Signal Integrity (SI) and Power Integrity (PI) Engineer to join our team, focusing on high-speed electrical wireline systems.

    The successful candidate will play a critical role in designing, analyzing, and optimizing high-performance interconnects, ensuring signal and power integrity in high-speed package, chip-on-board, PCB, and cable designs.

    What You'll Do

    • Conduct SI/PI simulations and analysis for high-speed interfaces (e.g., 106Gbps and higher PAM4 differential signaling)
    • Develop simulation models based on electromagnetic analysis for PCB traces, vias, connectors, cables, IC packages, and photonics interconnects to ensure optimal SI/PI performance
    • Perform frequency-domain and time-domain analysis, including S-parameters, impedance matching, crosstalk, return loss, insertion loss, and power supply AC noise analysis
    • Work closely with cross-functional IC design teams to optimize high-speed interface layout floorplans to optimize SI/PI performance across a wide range of different interconnect technologies
    • Define design guidelines and develop reference designs for high-speed interconnects and power distribution networks (PDN)
    • Work closely with internal teams and external partners for hardware design, PCB layout, and manufacturing to ensure optimal SI/PI performance
    • Validate SI/PI performance through lab measurements using oscilloscopes, vector network analyzers (VNAs), time-domain reflectometry (TDR), and other test equipment
    • Identify and mitigate signal degradation issues such as reflections, jitter, and noise coupling
    • Support package and PCB stack-up design, material selection, and layout optimization for high-speed signal routing
    • Drive improvements in design methodologies and best practices for high-speed electrical systems

    What You'll Need

    • Masters/PhD in Electrical/Computer Engineering, Engineering Science, or a related field
    • Previous experience with electromagnetic modeling and simulation
    • Strong understanding of microwave/RF and SI/PI fundamentals, including transmission line theory, s-parameters, crosstalk, channel simulation, PDN, and EMIR
    • Proficiency with EDA Tools: KeySight ADS, Ansys Electronic Desktop (HFSS and SIwave), Cadence Sigrity PowerSI/DC, or other similar simulation/modeling tools
    • Ability to interpret s-parameters, impedance profiles, and power distribution network characteristics
    • Experience with high-speed IC package and PCB design
    • Proficiency in using lab equipment such as oscilloscopes, TDR, VNA, and spectrum analyzers for signal integrity and power integrity validation

    It'd Be Amazing If You Had

    • Familiarity with IEEE Ethernet) and OIF standards
    • Experience with high-speed (e.g., 106Gbps and higher) NRZ and PAM4 SerDes
    • Understanding of digital and analog equalization and familiar with using IBIS-AMI model in channel simulation
    • Scripting knowledge (Python, Matlab, etc.) for automation of SI/PI simulations

    We have a flexible work environment to support and help employees thrive in personal and professional capacities. You'll also be eligible for competitive benefits, including:

    • Comprehensive health plan
    • Health Spending Account (HSA)
    • Wellness Spending Account (WSA)
    • Employee Assistance Program (EAP)
    • Paid Vacation
    • Paid Holidays
    • Parental Leave Top-Up Program
