Technician 4

• 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
• 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
• Provide clear issue reports with reproduction steps, logs, trace captures, and analysis
• 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)
• Follow and contribute to test plans, validation matrices, and engineering logs
• Ensure compliance with PCI‑SIG requirements and SD Association physical and protocol specifications
• Maintain detailed test records, failure reports and support certification activities
