NAND Custom Test Circuit Design Engineer

Job Title

NAND Custom Test Circuit Design Engineer

Role Summary

Design and validate custom test circuits for NAND flash memory, covering transistor-level digital, analog, mixed-signal, monitoring, control, and memory-array interface circuits. Collaborate with layout, product engineering, and lab teams to move designs from specification and simulation through silicon bring-up and production.

Experience Level

Entry-level (2+ years of relevant industry experience).

Responsibilities

Key responsibilities include:

• Develop, integrate, and optimize custom test circuit architectures for NAND designs.
• Interpret product specifications and define circuit functionality, interfaces, operating limits, controllability, observability, and validation criteria.
• Create and optimize schematics, device sizing, bias structures, sensing/monitoring paths, and multiplexers for test circuits.
• Analyze testability and robustness for quality, coverage, manufacturability, power, area, and reliability.
• Validate designs using XA, Verilog, and mixed-signal simulation; review post-layout results and drive closure.
• Work with layout teams on matching, parasitic sensitivity, shielding, routing, guard rings, device placement, and layout-dependent effects.
• Evaluate circuit risks including leakage, contention, floating nodes, device overstress, power sequencing, current density, EM/IR, and long-duration stress conditions.
• Create and debug test sequences and test modes for wafer- and package-level characterization.
• Support first-silicon bring-up, failure isolation, simulation-to-silicon correlation, and ramp to high-volume production.
• Use laboratory measurements and silicon data to identify root cause and recommend circuit, test-mode, characterization, or screening improvements.
• Apply AI-assisted engineering workflows and develop Python/scripting automation to accelerate review, simulation triage, waveform analysis, and documentation while maintaining engineering rigor.
• Document test-circuit methodologies, specifications, design decisions, validation results, silicon correlation, and technical recommendations.

Requirements

Must-have technical skills and practical experience:

• Hands-on experience in custom/analog and mixed-signal circuit design with transistor-level circuit and silicon-debug exposure.
• Strong understanding of CMOS device operation, leakage mechanisms, parasitics, PVT sensitivity, timing, loading, noise margin, power, and reliability principles.
• Proficiency with circuit build entry, waveform debugging, and post-layout verification.
• Experience with XA or equivalent fast transistor-level simulation, Verilog, and mixed-signal validation methodologies.
• Proficiency in Python or scripting for simulation automation, regression analysis, result extraction, and waveform processing.
• Ability to identify workflows suitable for AI, develop or adapt AI-enabled engineering solutions, and apply appropriate technical review and data protection practices.
• Strong problem-solving, attention to detail, and effective interpersonal skills for multi-functional global collaboration.

Preferred / nice-to-have:

• Familiarity with NAND flash architecture, peripheral circuits, internal signal access, and wafer/package test considerations.
• Laboratory experience with oscilloscopes, logic/signal analyzers, source-measure equipment, function generators, and hands-on silicon testing at wafer and package levels.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related field. The posting specifies 2+ years of relevant industry experience in addition to the degree.
