Senior Post-Silicon DDR Characterization Engineer

Join Arm's Chandler Characterization team to validate and characterize next-generation Arm SoCs and help customers bring products to market.
As a Senior Post-Silicon DDR Characterization Engineer, you will focus on DDR/LPDDR memory subsystems, characterizing silicon across process, voltage, temperature, and frequency conditions. You will collaborate across engineering teams to analyze results, debug issues, and improve silicon performance.
Responsibilities:

• Develop and enable system-level stress workloads on Linux and Bare-Metal SW environments!
• Collaborate with post-silicon validation team to leverage test content to characterize silicon at the system level.
• Debug and resolve system issues and bugs
• Develop test plans and implement tests for characterizing silicon at the system level

Required Skills and Experience :
We are looking for experience in pre- or post-silicon validation and characterization, with an understanding of silicon power, performance, and PVT behavior.

• Experience with DDR/LPDDR architectures, including training, calibration, timing, and PHY operation
• Software skills including C/C++, Arm assembly, Python, or scripting languages
• Experience with voltage/frequency margining and silicon operating limits
• Experience debugging silicon and system issues using scopes, logic analyzers, debuggers, or similar tools
• Ability to analyze data, solve complex problems, and communicate technical findings

"Nice To Have" Skills and Experience :
Experience with DDR/LPDDR PHY characterization, memory-controller interactions, and LPDDR4/4X, LPDDR5/5X, DDR4, DDR5, or related technologies is helpful.

• Experience characterizing memory performance, stability, operating margins, and failure behavior
• Experience developing Python automation for characterization and data analysis
• Experience with low-level C, firmware, hardware control, or silicon debug
• Experience with Arm-based SoCs, CPUs, or memory subsystems
• Understanding of system-level testing and correlation with manufacturing test

You will succeed in this role by collaborating effectively, continuing to learn, and applying strong analytical and interpersonal skills to sophisticated silicon challenges!
