NAND Designer / Layout

Job Title

NAND Designer / Layout

Role Summary

Design and optimize circuits for next-generation NAND flash memory, focusing on base-die, memory arrays, analog blocks, logic controllers, and interface circuitry. The role works within a cross-functional memory design team in Tokyo to deliver high-performance, production-ready NAND products.

This is an engineering role centered on circuit design, simulation, performance trade-offs (timing, area, power), and collaboration with layout and verification teams.

Experience Level

Mid-level engineer. Candidates should have several years of practical experience designing analog and mixed-signal circuits for memory or related high-performance semiconductor products.

Responsibilities

Key day-to-day responsibilities include:

• Design and optimize base die circuits for NAND flash products (memory, logic, analog).
• Run circuit simulations and behavioral models using industry-standard EDA tools.
• Analyze and optimize timing, area, and power trade-offs in NAND designs.
• Collaborate with layout engineers to ensure implementable and manufacturable designs.
• Work with verification and build teams to support integration and product delivery.

Requirements

Must-have technical skills and attributes:

• Strong expertise in analog and mixed-signal circuit design.
• Proven ability to identify technical issues and develop innovative solutions in high-performance memory development.
• Strong analytical skills and the ability to explain complex technical concepts clearly and logically.
• Effective communication and collaboration skills; experience working in cross-functional engineering teams.

Nice-to-have:

• Familiarity with NAND flash operation and multiple NAND product generations.
• Industry experience in memory product development.
• Experience using simulation tools such as HSPICE, FINESIM and behavioral languages such as Verilog.

Education Requirements

Preferred: Master's degree (MS) plus 5+ years' relevant experience, or Bachelor's degree (BS) plus 10+ years' relevant experience. Equivalent practical experience will be considered.

Reasonable accommodation: Individuals with disabilities may request reasonable accommodation for the application or interview process; contact hrsupport_japan@micron.com for assistance.
