As well, Rambus benefits are among the most comprehensive and competitive in the market today.

Responsibilities

You will assume both “hands-on” and leadership roles in the design of DDR5 memory buffer chips. You will be responsible for the successful execution of critical chip sub-systems and work in a team through all phases of development including specification, design, verification, and silicon evaluation. The primary focus of the position is transistor-level design of high performance and low power mixed-signal circuits in CMOS, which may include chip IO (Tx/Rx), clock synthesis and distribution (PLL/DLL), adjustable timing circuits (DCDL), voltage regulators, ESD, equalizers, crosstalk cancellation, etc. In addition to analog circuit expertise, job responsibilities include custom logic design, familiarity with static timing analysis, and proficiency in the construction of behavioral models using Verilog and Verilog-A. Furthermore, you will be called upon to both utilize and contribute to the development of tools, scripts, and design flows for robust validation of analog/digital interfaces. Other responsibilities include layout supervision, technical documentation, customer interaction and data preparation, presentation of results and evaluation of peer results in design reviews.

Qualifications

  • MSEE/Ph.D. with 2-3 years of analog/mixed-signal circuit design experience on chip products is required.
  • You must have designed critical circuit blocks in at least two high-speed (>5Gbps) mixed signal macros that were integrated into a standard product or ASIC and successfully went into mass production.
  • Record of achieving performance and power targets is required.
  • Specific knowledge or experience with DDR4/DDR5 DRAM and RCD/DB specifications is highly desirable, and chip design experience in DDR4/5 RCD/DB is a strong plus.
  • Experience with the following tools is required:  Hspice/Spectre and HspiceRF/SpectreRF, AFS, Verilog, Verilog-A, LVS/DRC verification, schematic capture and shell scripting.
  • Working knowledge of communication theory, control theory, power and signal integrity, equalization techniques, and noise analysis is recommended.
  • Low power and low noise design, design for manufacturability, design for testing, and silicon characterization and debug experiences are also desirable.
  • Excellent oral and written presentations skills are required for team presentations, as well as customer interaction and reviews.
  • Must be self-motivated, detail oriented, and work well in a team across multiple functional disciplines.
