Job overview

🔧 Firmware & BIOS Validation

  • Validated SSD firmware updates across multiple product lines, ensuring stability, performance, and compliance with NVMe/SATA standards.
  • Conducted compatibility testing of SSDs with various BIOS versions across OEM platforms (Dell, HP, Lenovo, etc.).
  • Collaborated with firmware developers to identify and debug issues, reducing FW-related field failures by 30%.
  • Performed regression testing after firmware updates to ensure no performance degradation or feature regression.
  • Authored and maintained automated test scripts for firmware validation using Python and proprietary tools.

📊 System & Performance Validation

  • Designed and executed system-level validation plans covering power cycling, thermal stress, and endurance scenarios.
  • Measured and analyzed SSD performance (IOPS, latency, throughput) using tools like CrystalDiskMark, FIO, and IOMeter.
  • Conducted BIOS-level validation for SSD boot capability, hot-plug detection, and NVMe enumeration in pre-boot environments.
  • Utilized PCIe analyzers and protocol decoders (e.g., LeCroy, Teledyne) to trace and resolve signal integrity and link training issues.

🤝 Cross-functional Collaboration

  • Interfaced with BIOS, firmware, hardware, and manufacturing teams to ensure SSD readiness for product launch.
  • Worked with OEM partners to validate custom firmware builds and resolve compatibility issues pre-production.
  • Participated in daily scrum meetings to report validation status, blockers, and test progress.

🧪 Test Automation & Documentation

  • Created detailed validation reports and test matrices for internal use and customer delivery.
  • Documented and tracked bugs in Jira/Confluence, contributing to continuous improvement in test coverage.
