Job Description

Validation & Testing

• Perform functional, electrical, and interface‑level testing of PCIe/NVMe and SD/SD‑Express cards.
• Execute performance tests (sequential, random, sustained throughput, SLC/TLC behavior, GC events).
• Run camera‑pattern tests and evaluate performance drops, latency, and buffering behavior (common for SD Express).
• Use protocol analyzers (PCIe, SD bus), logic analyzers, oscilloscopes, and host debug tools.
• Validate PCIe link training, LTSSM states, lane negotiation, reset behavior, and power‑state transitions.
• Verify SD/UHS/SDR modes, card‑detect, hot‑plug, and backward‑compatibility behavior.

B. Debugging & Issue Isolation

• Capture and analyze PCIe or SD traffic traces; identify protocol violations or timing/latency anomalies.
• Debug SLC→TLC transitions, garbage‑collection behavior, and performance drops under load.
• Work cross‑functionally with FW/HW teams to root‑cause failures (e.g., drops due to TLC compaction, GC triggers—seen often in camera‑throughput cases).
• Provide clear issue reports with reproduction steps, logs, trace captures, and analysis.

C. System Integration & Characterization

• Evaluate product behavior on various hosts (PCs, cameras, test fixtures, embedded hosts).
• Conduct temperature, voltage, and stress testing including high‑resolution camera workloads.
• Validate new ASIC/board revisions, connectors, PHY behavior, signal integrity, and thermal characteristics.
• Assist in bring‑up of prototypes and PoC cards (uSD/SD/SD Express, PCIe‑based modules).

D. Documentation & Compliance

• Follow and contribute to test plans, validation matrices, and engineering logs.
• Ensure compliance with:
  • PCI‑SIG requirements (config space, link stability, enumeration, protocol layers)
  • SD Association physical and protocol specifications
• Maintain detailed test records, failure reports and support certification activities.
