ATE Engineer (WFH)

About the Company Our client is an international technology company seeking an experienced Automated Test Equipment Engineer to support semiconductor testing and production operations. Based in Taipei, this role involves developing and maintaining test programmes, monitoring production performance, analysing yield issues, and collaborating with internal engineering teams and external manufacturing partners. The position offers opportunities to work with global teams, with remote work and occasional on-site support at local manufacturing facilities. The ideal candidate combines hands-on semiconductor test experience with strong analytical and programming skills, along with the ability to independently investigate production issues and drive continuous improvement.

Key Responsibilities

• Develop, maintain, and optimise product test programmes to support semiconductor production and quality requirements.

• Verify test processes and ensure automated test equipment operates reliably and consistently.

• Support mass production activities, including production release, output monitoring, excursion management, and coordination with external manufacturing partners.

• Conduct Low Yield Analysis to identify yield loss, investigate root causes, and recommend corrective actions.

• Perform Failure Analysis (FA) in collaboration with Design, Process, and Quality teams to resolve product and production issues.

• Analyse test data, monitor yield trends, and prepare reports with actionable recommendations for continuous improvement.

• Troubleshoot test programme, equipment, and production-related issues to minimise disruption and improve test efficiency.

• Develop scripts and automation tools to improve testing workflows and data analysis efficiency.

• Work with global engineering teams and external suppliers to coordinate technical issues and share best practices.

• Provide on-site technical support at manufacturing and test facilities when required.

• Participate in international business travel to support technical collaboration and production-related activities.

Requirements

• Bachelor’s degree or above in Electrical Engineering, Electronics Engineering, or a related technical discipline.

• At least 3 years of experience in semiconductor testing, product test engineering, or ATE-related engineering.

• Hands-on experience developing, debugging, or maintaining semiconductor test programmes.

• Proficiency in at least one programming or scripting language, such as Python or LUA.

• Strong data analysis skills, with the ability to interpret test results, identify yield trends, and investigate production anomalies.

• Experience with mass production test flows, production release, and excursion management.

• Practical experience in Low Yield Analysis, Failure Analysis, or root-cause investigation.

• Familiarity with ATE platforms, preferably Teradyne or comparable automated test systems.

• Understanding of semiconductor test flows, including Wafer Sort and Final Test.

• Experience collaborating with OSATs or external test and manufacturing partners.

• Familiarity with statistical analysis or data visualisation tools such as JMP, Spotfire, or equivalent platforms.

• Strong problem-solving, communication, and cross-functional collaboration skills.

• Good written and spoken English for communication with international teams.

Experience in IC testing, optical or optoelectronic products, or other specialised semiconductor test applications would be advantageous.

The Opportunity

This position offers hands-on involvement in semiconductor test development, production support, yield improvement, and technical problem-solving.

You will work with cross-functional engineering teams and external manufacturing partners, gaining exposure to different testing environments and production challenges while contributing to product quality and manufacturing efficiency.

The role combines ATE test engineering, data analysis, programming, and production troubleshooting, making it suitable for engineers who enjoy both technical investigation and practical problem-solving.

What's Next

If you have experience in semiconductor testing, ATE, and yield analysis, and enjoy solving technical challenges in a production environment, we welcome your application.
