RAS Validation Lead

Responsibilities

• Lead RAS validation strategy and execution for GPU server platforms, including fault injection, detection coverage, and recovery verification
• Partner with GPU system designers to analyze hardware failures and align on fault handling requirements for DDR, HBM, CPU, and GPU subsystems
• Characterize fault propagation paths from hardware detection through firmware and OS layers
• Validate BMC and out-of-band management visibility via IPMI, Redfish, and MCTP/PLDM protocols
• Debug complex failure modes spanning GPU/CPU architecture, memory subsystems, and PCIe/NVLink fabric
• Drive root-cause analysis for RAS failures and provide input on platform design decisions
• Define RAS coverage metrics and maintain traceability from hardware fault models to test coverage
• Collaborate with firmware and software teams to validate OS-level error handling and runtime recovery flows

Requirements

• 5+ years of experience in hardware validation, platform reliability engineering, or silicon validation on server-class compute systems
• Deep understanding of CPU and GPU architecture, memory subsystems (DDR, HBM), and interconnect fabrics (PCIe, NVLink)
• Strong knowledge of RAS concepts including ECC, fault containment, and machine check architecture
• Hands-on experience with fault injection methodologies at hardware, firmware, and software levels
• Familiarity with system management interfaces such as BMC, IPMI, Redfish, and MCTP/PLDM
• Experience working with silicon vendors or ODM partners on hardware failure analysis
• Strong scripting skills in Python for test automation and log analysis
• Must meet ITAR requirements (U.S. citizen, lawful permanent resident, or protected individual)

Benefits

• Equity in Cowboy Space Corp.
• Medical, dental, and vision insurance
• 401(k) retirement savings plan
• Paid time off and 10 paid holidays
• Paid parental leave
