Test Engineer (Manufacturing)

. We are seeking a Sustaining Test Engineer to support and improve high-volume semiconductor test operations across final test and wafer sort. In this role, you’ll work closely with internal cross-functional teams and OSAT partners to resolve production test issues, qualify new test hardware and software, and ensure stable mass production. This is a hands-on role involving data analysis, test debug, and process improvements for both mature and new products. If you have strong problem-solving skills, enjoy working with test platforms, and are eager to grow in a fast-paced environment, we’d love to hear from you.

🔧 What You’ll Do

• Analyze production test data and provide timely dispositions for Final Test and Wafer Sort issues

• Support test-related qualifications and buy-off for test hardware, software, and systems

• Drive test program releases and implement necessary revisions and improvements

• Provide remote debugging and support for ATE systems, test programs, and product issues

• Work closely with OSAT partners to ensure smooth test operations and minimize line-down risks

• Collaborate with internal engineering teams to address test coverage and quality issues

• Prepare qualification reports and maintain documentation

• Occasional travel to OSAT sites and other company offices (domestic/international)

🎓 Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field

• Hands-on experience with ATE platforms (e.g., ETS-88, ETS-364, uFlex, iFlex, Advantest, LTX)

• Familiar with probe and handler operations in wafer sort and final test

• Experience in production test debug and sustaining activities

• Proficient in at least one programming/scripting language (e.g., Python or C++)

• Experience with test hardware setup (probe cards, load boards, etc.)

• Comfortable communicating in English (written and spoken)

🌟 Preferred Traits

• Independent, proactive, and quick to learn

• Strong team player with a collaborative mindset

• Committed to continuous learning and professional growth

• Calm under pressure and capable of handling production escalations

• Detail-oriented and organized with good documentation habits
