PCI Express Validation Engineer

Position: PCIe Validation Engineer

Location: San Jose, CA

Exp: 5-8 years

PCIe Gen 4/5/6, CXL, RISC-V, ARM, Oscilloscope, Multimeter, Logic & Power Analyzer, BERTS C/C++, Python, Perl, Windows, Linux

• Take lead responsibility for validating PCIe and its subsystems on multiple SoC platforms.
• Define comprehensive test plans and execute tests covering memory training procedures, performance benchmarks, stress scenarios, timing margin analysis, and overall reliability.
• Collaborate with design and firmware teams to develop, integrate, and debug firmware essential for PCIe training. Write necessary firmware components (like bootloaders, PCIe drivers, test hooks) to enable testing.
• Integrate and debug firmware for PCIe initialization and training, specifically on systems using RISC-V or ARM processors.
• Work closely with software and hardware teams to ensure firmware and hardware components interact correctly. Coordinate with board and Signal/Power Integrity (SI/PI) teams for related evaluations.
• Utilize standard lab equipment (oscilloscopes, logic analyzers, BERTs, power analyzers) for test execution, data collection, and troubleshooting memory-related issues. Perform root cause analysis for failures.
• Develop scripts (Python, Perl, C/C++) to automate test procedures and validation workflows.

5 to 8 years of experience

• 5+ years of SOC validation experience
• At least 4 years of experience in post-silicon PCIe subsystem validation
• Strong C/C++ programming skills, particularly for low-level code (like hardware abstraction layers) used in system bring-up. Proven experience integrating and debugging firmware in PCIe validation or general SoC environments.
• Deep understanding of PCIe protocols (Physical, Data Link, Transaction layers), PCIe Gen 4/5/6, and CXL
• Experience with silicon bring-up processes and Hands-on experience with PCIe protocol analyzers and oscilloscopes.
• Familiarity with embedded operating systems and the typical boot sequences.
• System-level PCIe performance tuning and characterization.

Experience with Linux and Windows operating systems
