The posting

Job Description

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

  • Bachelor's 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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
