Senior Post-Silicon PCIe 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 PCIe Characterization Engineer, you will focus on PCIe interfaces, characterizing silicon across process, voltage, temperature, and frequency conditions. You will collaborate across engineering teams to analyze results, debug issues, and improve silicon performance.

• 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.

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 PCIe architecture, including link initialization, training, equalization, 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 PCIe, silicon, and system issues using protocol analyzers, scopes, debuggers, or similar tools
• Ability to analyze data, tackle sophisticated problems, and communicate technical findings

Experience with PCIe PHY characterization, link behavior, signal integrity, and protocol-level debug is helpful, including experience with PCIe Gen4, Gen5, Gen6, or related high-speed interfaces.

• Experience characterizing PCIe performance, stability, operating margins, and failure behavior
• Experience with PCIe protocol analysis, error handling, link recovery, or compliance testing
• Experience developing Python automation for characterization and data analysis
• Experience with Arm-based SoCs, CPUs, PCIe controllers, or high-speed interfaces
• 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 and PCIe challenges!
