Silicon Validation Engineer

The Silicon Validation Engineer will be responsible for developing DDR PHY/DRAM initialization drivers and firmware for memory tuning and optimization. This role involves participating in pre/post-silicon bring-up of memory subsystems, validating silicon features for DDR/GDDR/HBM, and contributing to test plan execution and failure analysis. Candidates should have a minimum of 3 years of firmware experience in a post-silicon validation environment, expertise in DDR initialization, and strong debugging skills.

Must Have

• Minimum of 3 years of experience with firmware in a post-silicon validation environment
• Working experience with DDR4/5 controller and PHY, JEDEC and DFI specifications
• Expertise in DDR initialization firmware, controller features, equalization features validation, and related tuning
• Deep understanding of server boot-up flow, specifically DDR initialization process
• Strong debugging skills at both SoC and system levels, including DDR protocol-level and signal integrity-level issues
• Experience in DDR RAS, Performance, Power features, and related firmware routines for tuning/optimization
• Experience in microcontroller and embedded systems programming using C/C++
• Proficiency in script languages such as Perl or Python, Linux shell script
• Must be a self-starting team player who can work with minimal guidance

Responsibilities and Opportunities

• Develop DDR PHY/DRAM initialization drivers and conduct testing
• Develop firmware for memory tuning and optimization routines
• Participate in pre/post-silicon bring-up(power-on) of memory subsystems
• Develop software routines for DDR PHY/DRAM initialization, training, equalization, IO tuning, SI/PI optimization, etc.
• Validate and characterize the silicon features for DDR/GDDR/HBM
• Contribute to writing test conditions, executing test plans in pre/post-silicon environments, perform failure analysis to identify root causes, and develop innovative solutions
