NAND Custom Test Circuit Design Engineer

Job Title

NAND Custom Test Circuit Design Engineer

Role Summary

Design, validate, and optimize custom test circuits for NAND flash memory at the transistor and mixed-signal levels. Work with layout and product engineering teams to ensure testability, manufacturability, and robust silicon bring-up. Use simulation, lab measurement, and AI-assisted tooling to accelerate design review and fault isolation.

Experience Level

Mid-level — minimum 2+ years of relevant industry experience.

Responsibilities

Key responsibilities include design, validation, and cross-functional support for custom test circuits used in NAND memory development and production.

• Develop, integrate, and optimize custom test circuit architectures (transistor-level digital, analog, mixed-signal, monitoring, control, and memory-array interfaces).
• Derive circuit functionality, interfaces, operating limits, controllability/observability, and validation criteria from product specifications.
• Create and review schematics, device sizing, bias structures, sensing/monitoring paths, and multiplexing relevant to test circuits.
• Analyze testability and robustness to meet quality, coverage, manufacturability, power, area, and reliability targets.
• Validate circuits using fast transistor-level (XA) simulations, Verilog, and mixed-signal validation; review post-layout results and drive closure with layout teams.
• Support first-silicon bring-up, debug, characterization, failure isolation, and simulation-to-silicon correlation; work with Product Engineering through production ramp.
• Create and debug test sequences and test modes for wafer and package level validation; use lab measurements and silicon data for root-cause and design improvements.
• Evaluate circuit risks including leakage, contention, floating nodes, overstress, power sequencing, current density, EM/IR, and long-duration stress.
• Apply AI-assisted engineering workflows and develop scripting/automation to accelerate circuit review, simulation triage, waveform analysis, and documentation.
• Document methodologies, specifications, design decisions, validation results, silicon correlation, and technical recommendations.

Requirements

Must-have technical skills, tools, and behaviors for this role.

• Hands-on experience in custom/analog circuit design, mixed-signal design, memory peripheral circuit design, or product engineering with transistor-level circuit and silicon-debug exposure.
• Strong understanding of CMOS device operation, transistor-level design, 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 tools, Verilog, and mixed-signal validation methodologies.
• Proficiency in Python or similar scripting for simulation automation, regression analysis, result extraction, and waveform processing.
• Ability to identify workflows that benefit from AI, and to develop or adapt AI-enabled engineering solutions while applying appropriate technical review and data protection practices.
• Strong problem-solving skills, attention to detail, and effective interpersonal skills for global, multi-functional collaboration.

Nice-to-have:

• Understanding of NAND flash memory architecture, test modes, peripheral circuits, internal signal access, and wafer/package test considerations.
• Laboratory skills using oscilloscopes, logic/signal analyzers, source-measure equipment, function generators, and hands-on wafer/package silicon testing.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related technical field, with a minimum of 2+ years of relevant experience; equivalent practical experience may be considered.
