  • Overview

    At Rambus, we are turning incredible possibilities into everyday reality by helping to deliver the innovations that greatly impact the world we live in. We create leading-edge semiconductor and IP products, spanning memory and interfaces to security to smart sensors. Our products are integrated into tens of billions of devices and systems around the globe, running critical applications for Big Data, Internet of Things (IoT), mobile, consumer and media platforms.


    And our history runs deep – we have been in Silicon Valley for 25+ years and are continually anticipating key technology trends and are developing innovations that drive market changes. From a pure IP provider to becoming a fabless chipmaker, Rambus is evolving to address critical challenges in the semiconductor industry.


    As a dynamic organization, we are always seeking to hire exceptional talent to join some of the brightest inventors and engineers in the world to explore their passions to develop products that have real life impact. As well, Rambus benefits are among the most comprehensive and competitive in Silicon Valley.


    This is a highly impactful position for the System Solutions Engineering team of the Rambus IP Cores division.  We are looking for a highly-experienced leader to build, lead and drive direction in signal and power integrity in advanced SerDes PHY development.  You will participate in IP generation and technology evangelization and contribute towards new product initiatives leveraging this critical IP. You are a team player with excellent written and verbal communication skills, and you are self-motivated and detail-oriented with the ability to work with peers across groups and projects.


    • Leadership role in building a strong global organization driving robust SI/PI hardened advanced interface memory and SerDes IP products
    • Define advanced architectures and specifications for robust multi-protocol SerDes IP solutions together with the architecture and design teams
    • Develop Signal and Power Integrity methodologies for the analysis, modeling and simulation of link channels and global power distribution
    • Build voltage, timing and power supply budgets across channel components including noise effects (reflections, simultaneous switching noise and crosstalk)
    • Design, analyze and document guidelines for full link interconnect
    • Perform channel margin analysis to provide design tradeoffs between package, board, connector and cables
    • Develop IBIS AMI IO and package/system channel simulation models
    • Correlate Tx and Rx SerDes simulation models with measurements
    • Perform system level timing analysis to implement SI guidelines and checklists
    • Best in class team validated though customer interactions, patent development, conference and journal publications


    • MS / Ph.D. in Physics, Electrical Engineering with emphasis on electromagnetics (EM), SI, PI, Analog, RF or advanced packaging
    • 5-10 years of experience in signal/power integrity methodology development, modeling and simulations of high speed SERDES links
    • Strong knowledge of EM and transmission line theory, equalization techniques, S-parameters, crosstalk, SSN and jitter mechanisms
    • Working experience with NRZ and PAM4 signaling in high-speed/low-power serial links
    • Working knowledge of physical architecture with experience in BGA assignment methodology and ability to simulate system level trade-offs
    • Practical lab characterization experience with advanced scopes, BERTs and VNA/TDR
    • Experience in extraction/CAD tools: HFSS, ADS, MATLAB/Simulink, Cadence Virtuoso, Hspice/Spectre. Shell scripting / programming experience preferred. Familiarity with RedHawk/Totem or XcitePI and Virtuoso is a strong plus
    • Strong problem solving and communication skills and willingness to work with customers and cross-functionally


    Rambus offers an extremely competitive compensation package, which includes a strong base salary, bonus, equity, matching 401(k), employee stock purchase plan, comprehensive medical and dental benefits, time-off program and gym membership.
