Macro Analog Design Engineer

Job Title:

Macro & Functional Design Engineer

Department:

Design Technology Division, Enablement

Location:

Tokyo, Hokkaido (Japan), Albany, NY (USA)

Position Summary:

This position focuses on macro and custom layout design for evaluation macros, memory, logic, and analog/mixed-signal functional blocks in advanced semiconductor process and device development.

Through layout optimization considering PPA (Performance, Power, Area), reliability, manufacturability (DFM), and yield, the engineer contributes to the validation and advancement of process and device technologies.

The engineer will work closely with circuit designers, process/device teams, and PDK teams, and will play a key role throughout the development phases from early design through volume ramp.

You will focus on the implementation stages (Synthesis and PnR) of the digital reference flow. Additionally, you will lead the adoption of next-generation automation tools, including AI/ML-driven DSE (Design space exploration)

Key Responsibilities:

Macro Layout (Primary Responsibility)

• Macro/custom layout design for memory, logic, and analog/mixed-signal functional blocks
• Layout variation design intended for device characterization and process validation
• Layout optimization considering DRC/LVS/DFM/DFY, EMIR, and reliability
• Layout design and revision control for test chips (TEGs) and evaluation macros
• Support correlation analysis between silicon results (electrical characteristics, reliability, yield) and layout conditions

Cross-Functional Collaboration

• Collaborate with circuit designers to define layout constraints reflecting circuit intent
• Work with process and device development teams to define evaluation conditions and viewpoints
• Provide feedback to PDKs, including design rules and layout guidelines

Stretched Goals Include:

• Contribute to circuit design for memory, logic, or analog blocks
• Perform circuit simulation and variability analysis using SPICE or equivalent tools
• Take ownership of post-layout circuit verification
• Propose optimization by integrating circuit conditions and physical implementation conditions
• Lead development of evaluation macros spanning both circuit and layout domains

Required Qualifications:

• Bachelor’s degree or higher in Semiconductor Engineering, Electrical Engineering, Physics, or a related field
• 3+ years of hands-on experience in macro/custom layout design
• Experience with DRC/LVS-based verification flows
• Fundamental knowledge of advanced process design rules and manufacturing constraints
• Basic understanding of circuit operation

Preferred Qualifications:

• Experience with advanced technology nodes (7nm or below, FinFET/GAA, etc.)
• Experience in memory or analog/mixed-signal circuit design
• Cross-functional experience with process and/or device development teams
• Ability to communicate technical topics effectively in English

Desired Attributes:

• Strong technical curiosity and proactive approach to problem solving
• Ability to collaborate effectively with cross-functional teams
• Flexibility to work in fast-paced and uncertain advanced R&D environments

Benefits

• Comprehensive Health, Dental and Vision coverage, fully at company’s expense (no deductibles)
• 401k with no employer match
