Technician 4

Sandisk understands how people and businesses consume data and we relentlessly innovate to deliver solutions that enable today’s needs and tomorrow’s next big ideas. With a rich history of groundbreaking innovations in Flash and advanced memory technologies, our solutions have become the beating heart of the digital world we’re living in and that we have the power to shape.

Sandisk meets people and businesses at the intersection of their aspirations and the moment, enabling them to keep moving and pushing possibility forward. We do this through the balance of our powerhouse manufacturing capabilities and our industry-leading portfolio of products that are recognized globally for innovation, performance and quality.

Sandisk has two facilities recognized by the World Economic Forum as part of the Global Lighthouse Network for advanced 4IR innovations. These facilities were also recognized as Sustainability Lighthouses for breakthroughs in efficient operations. With our global reach, we ensure the global supply chain has access to the Flash memory it needs to keep our world moving forward.

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.
