About the role

Lead end-to-end RAS validation strategy for GPU server platforms used in space-based high-performance computing, including fault injection, detection, containment, and recovery. Collaborates with silicon vendors and ODM partners to analyze hardware failures, validate OS/firmware error handling, and drive fault-detection and serviceability improvements for GPU/CPU/memory subsystems in a space environment.

Responsibilities

  • Lead RAS validation strategy and execution for GPU server platforms, including fault injection, detection coverage, and recovery verification.
  • Partner directly with GPU system designers to analyze hardware failures, review silicon errata, 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, and validate that error signals are correctly classified, logged, and acted upon.
  • Validate BMC and out-of-band management visibility into hardware health events via IPMI, Redfish, and MCTP/PLDM protocols.
  • Debug complex failure modes spanning GPU and CPU architecture, memory subsystems, PCIe/NVLink fabric, and system management firmware.
  • Drive root-cause analysis for RAS failures discovered during validation and work with partners to provide input on platform design decisions that affect fault detection and serviceability.
  • Define RAS coverage metrics and maintain traceability from hardware fault models to test coverage.
  • Collaborate with firmware, software, and platform teams to validate OS-level error handling, ACPI error interfaces (EINJ, BERT, HEST), and runtime error recovery flows.

Qualifications

  • Bachelors degree in Electrical Engineering or a related discipline.
  • 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, including memory subsystems (DDR, HBM), cache hierarchies, and interconnect fabrics (PCIe, NVLink, XGMI).
  • Strong knowledge of RAS concepts: error detection and correction (ECC), fault containment, error propagation, machine check architecture (MCA/MCI), and recovery mechanisms.
  • Hands-on experience with fault injection methodologies at hardware, firmware, and software levels.
  • Familiarity with system management interfaces including BMC, IPMI, Redfish, and MCTP/PLDM.
  • Experience working directly with silicon vendors or ODM partners on hardware failure analysis and RAS gap closure.
  • Strong scripting skills in Python or equivalent for test automation and log analysis.
