Staff Post-Silicon DDR Characterization
$198,100 - $268,000 USD yearly
Characterize DDR/LPDDR memory subsystems across PVT and frequency conditions for Arm SoCs.
Originally posted 6 November 2026 by the employer.
About the role
As a Staff 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.
What you'll do
- Develop and enable system-level stress workloads on Linux and Bare-Metal SW environments.
- Collaborate with the 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.
What you'll need
- 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.
Nice to have
- Experience with DDR/LPDDR PHY characterization, memory-controller interactions, and LPDDR4/4X, LPDDR5/5X, DDR4, DDR5, or related technologies.
- 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.
