Background
Driven by strong and growing demand for power semiconductor devices, particularly in AI-related applications, improving factory productivity has become an urgent priority.
We are seeking talented engineers who can contribute broadly as Device Engineering / Process Integration Engineers, supporting activities ranging from new technology development and new product introduction to yield/quality improvement of mass production products, process optimization, cost reduction, and troubleshooting.
Roles & Responsibilities
In an 8-inch wafer fabrication facility, you will act as a technology owner for Analog IC processes, leveraging expertise in device engineering and process integration to drive development and manufacturing excellence.
- Lead and execute development and transfer projects for new technologies and new products
- Improve product quality and yield through process design and optimization from development through mass production
- Drive continuous improvement of quality, yield, and reliability for existing mass production products, contributing to technology robustness, cost reduction, and productivity enhancement
- Manage manufacturing conditions for production products (Control Plans, FMEA, SPC)
- Perform root cause analysis of issues and implement corrective actions based on risk management, including recurrence prevention (8D, FTA, Why-Why analysis, Risk Assessment, etc.)
Key Relationship
- Direct Report: Manager, Device Engineering Department
- Key Interfaces: Engineers and managers within Aizu Wafer Fab, Global Engineering Teams
Qualifications (Required)
- Bachelor’s degree or higher in engineering or a related field
- Experience in device engineering or process integration in a semiconductor wafer fabrication environment (Minimum ~5 years)
- Fundamental knowledge of IC processes, device physics, electrical characteristics/testing, analog IC circuits, and reliability
- Understanding of product specifications (SPEC) and design margin concepts
- Hands-on experience in data analysis (yield, electrical characteristics, defect/failure analysis) and strong problem-solving skills
- Practical experience in identifying root causes and implementing corrective actions for yield loss or performance issues
- Experience leading cross-functional projects involving manufacturing, process engineering, design/product development, quality, and backend operations
- Ability to communicate effectively in English (email and web meetings) with global teams and U.S. headquarters
- Business-level English proficiency (e.g., TOEIC score of ~600 or higher)
- Japanese language proficiency (equivalent to JLPT N2 level or above)
- Valid work authorization that permits employment in Japan at the time of application
- No visa sponsorship available for this position
Preferred Qualifications
- Experience as a technical lead or engineer in new technology development or technology transfer projects
- Experience in semiconductor circuit design, device simulation, or test development
- Knowledge and hands-on experience with semiconductor front-end processes and equipment
- Leadership experience in yield improvement or process optimization projects
- Ability to communicate effectively in technical discussions in English meetings
- Experience working in a multinational or global company environment is a plus
- Experience in driving process optimization and business improvement using AI technologies
Ideal Candidate Profile
- Continuously improves personal skills and can adapt to broader and deeper technical responsibilities
- Understands factory and departmental KPIs and is committed to achieving them
- Demonstrates strong ownership of products/technologies and drives problem-solving and improvements through to completion
- Able to identify root causes and solve problems logically and systematically
- Proactively identifies risks and implements preventive actions through risk assessment
