• ≥3 years' experience supporting or developing complex SoC/silicon products for Server, Storage, and/or Networking applications. 


• Professional attitude with the ability to prioritize a dynamic list of multiple tasks, to plan and prepare for internal meetings in advance, and to work with minimal guidance and supervision. 


• Entrepreneurial, open-mind behavior and can-do attitude. Think and act with the customer in mind! 


• Proven track record solving problems independently. 

Required Experience 

• Familiarity with DDR4/5 memory standards and DIMM configuration, experience in system testing, characterization, margin analysis and optimization 


• Working knowledge of key, high-speed design blocks such as PLL’s, DFE, Tx EQ 


• Strong python scripting ability: knowledge of object-oriented programming and basic dev ops using git for source control and collaboration 


• Deep background in developing bench automation techniques, preferably using Python, with emphasis on execution efficiency, repeatability, and data analysis. 


• Proficiency using high-speed lab equipment such as BERT, Oscilloscope/high-speed probe, and VNA 

Preferred Experience 

• Hands-on experience with signal integrity, especially as it relates to multi-rank DDR and DDR termination schemes 


• Working knowledge of C or C++ for embedded FW 


• Familiarity with PCIe/CXL compliance standards and ability to drive electrical compliance testing at industry workshops 


• Experience working with DRAM memory vendors on DDR4 or DDR5 to identify issues and working with internal SoC HW/FW teams to improve memory calibration and tuning sequences 


• Working knowledge of common serial data specifications such as I3C, I2C, SPI, etc 


• Knowledge of memory subsystem compliance and RAS is a plus. 


• Knowledge of schematic capture and PCB layout tools from Cadence, Altium, etc. 


• Knowledge of simulation tools such as MATLAB, Keysight ADS, PLTS for data analysis and modeling of signal integrity issues.
