Sr Test Engineer

We are seeking an experienced Semiconductor Test Engineer to join our engineering team in Kodaira Tokyo Japan.

This is a hands-on technical role with the opportunity to develop and deploy production test solutions for advanced semiconductor products. You will work across the full test-development lifecycle from test strategy and hardware development through characterization qualification production release and continuous improvement.

The role has a strong focus on quality manufacturability test coverage test efficiency yield and cost of test while providing opportunities to solve challenging technical problems and collaborate with engineering and manufacturing teams around the world.

Key Responsibilities

• Develop and implement semiconductor test strategies test plans DFT requirements test methods and ATE solutions for wafer sort/probe characterization qualification and final production test.
• Develop debug optimize and maintain ATE test programs using C/C and platform-specific programming environments with focus on test coverage measurement accuracy test time multisite efficiency yield and cost of test.
• Develop robust test solutions for power ICs and analog/mixed-signal semiconductor products including appropriate techniques for high-current testing.
• Design and debug test hardware including load boards DUT interface boards probe interfaces and associated circuitry.
• Validate test solutions through pre-silicon simulation to verify test methods test-program functionality and ATE implementation prior to first silicon.
• Apply strong analog and mixed-signal engineering fundamentals to troubleshoot complex interactions among the device ATE test program test hardware and manufacturing environment.
• Perform test-method validation and production-readiness activities including ATE-to-bench correlation spike-check characterization GR&R guardband analysis and test-limit validation.
• Drive improvements in test time multisite efficiency yield test robustness and cost of test.
• Establish test-development milestones schedules dependencies technical risks and mitigation plans and communicate progress and issues clearly to project stakeholders.
• Collaborate with product design DFT systems manufacturing quality and other engineering teams across Japan and global locations.
• Provide technical guidance and mentoring to other engineers and contribute to continuous improvement of test engineering methods and processes.

Qualifications :

Qualifications

• Bachelors degree in Electrical Engineering Computer Engineering Electronics Engineering or a related technical field or equivalent relevant engineering experience.
• 4 years of semiconductor test engineering experience preferably involving analog mixed-signal power or automotive semiconductor products.
• Hands-on experience developing and debugging ATE test programs and test hardware for wafer sort/probe and/or final production test.
• Experience with semiconductor ATE platforms such as Teradyne ETS-88/ETS-800 Cohu DiamondX or equivalent platforms.
• Strong understanding of analog and mixed-signal electronics including measurement accuracy signal integrity grounding power delivery and troubleshooting techniques.
• Experience with power IC or other high-current semiconductor devices and associated test methodologies.
• Experience with pre-silicon simulation or simulation-based validation of semiconductor test methods and ATE test programs is an advantage.
• Experience with schematic capture and PCB design tools such as Altium Designer Cadence/OrCAD or equivalent.
• Working knowledge of semiconductor production-test methodologies including characterization qualification correlation GR&R sampling multisite testing production release test-time optimization yield improvement and cost-of-test reduction.
• Strong analytical and troubleshooting skills with the ability to independently investigate complex technical issues and drive them toward resolution.
• Strong communication and collaboration skills with the ability to work effectively in a multicultural and geographically distributed engineering organization.
• Experience with automotive semiconductor products and associated qualification or production requirements is an advantage.

Language Skills

• English: Ability to communicate effectively in a global engineering environment
• Japanese: Preferred but not required. Japanese proficiency is an advantage for collaboration with local teams in Japan.
