    Job Title: SI/PI Engineer

    Reports To: VP of Electrical Engineering

    Company Overview:

    Netlist Inc. (NASDAQ: NLST) is a leading provider of high-performance modular memory subsystems and next-generation storage-class memory solutions. We specialize in cutting-edge technologies that enable innovation in AI, cloud computing, and enterprise infrastructure. Our product portfolio includes DDR4/DDR5 DIMMs, NAND-based SSDs, and advanced interconnect technologies such as CXL and PCIe.

    Join our world-class engineering team and be part of shaping the future of memory and storage architecture.

    Position Summary:

    We are seeking a highly skilled SI/PI Engineer to ensure optimal signal and power integrity in high-speed digital systems. This role involves simulation, modeling, and validation of PCB and package designs to support reliable performance across a range of products, including memory modules, SSDs, and semiconductor devices.

    Key Responsibilities:

    • Perform PCB level signal integrity (SI) and power integrity (PI) simulations for high-speed interfaces and interconnects (e.g., DDRx, LPDDRx, CXL, NAND flash).
    • Analyze and optimize power delivery networks (PDN) for low noise and stable operation.
    • Develop and maintain SI/PI models and databooks for packages and boards.
    • Collaborate with layout, silicon, and system design teams to resolve SI/PI issues.
    • Conduct pre- and post-layout simulations using tools like Cadence Sigrity, Siemens HyperLynx, Ansys HFSS, and HSpice.
    • Support lab validation using oscilloscopes, TDRs, VNAs, and other test equipment.
    • Document design guidelines and best practices for SI/PI performance.

    Required Qualifications:

    • Bachelor's or Master's degree in Electrical Engineering or related field and five years' experience in design and simulation of electronic systems.
    • Strong understanding of electromagnetic theory, transmission lines, and PDN design.
    • Experience with simulation tools (e.g., Siemens HyperLynx, Cadence Sigrity, ADS, HFSS, HSpice).
    • Experience with PCB design tools (Cadence Orcad schematic capture and Allegro layout)
    • Familiarity with PCB stack-up design and layout constraints for high-speed signals.
    • Hands-on experience with lab equipment for SI/PI validation.

    Preferred Qualifications:

    • Knowledge of memory technologies, such as DDR4/DDR5 and LPDDR4/5, and memory module design is highly desirable
    • Knowledge of package design and modeling.
    • Scripting skills (e.g., Python, Perl) for automation.
    • Experience in electronics or semiconductor industries.
