• Ensure all test program changes are fully validated, documented, and released in accordance with quality management requirements. 

Issue Resolution & Customer Containment 

• Lead root-cause analysis activities for test-related customer returns and field issues. 
• Implement containment actions focused on improving test coverage, eliminating test holes, and preventing recurrence. 
• Provide timely and accurate technical responses to support internal quality, customer service, and product engineering teams. 

NPI, Industrialization & Production Support 

• Support new product introduction (NPI), industrialization and smooth transfer of test programs, hardware, and test flows between global manufacturing locations. 
• Monitor and drive improvements in test time, equipment utilization, and parallel test capability. 
• Ensure program compatibility and correlation across multiple ATE platforms and sites. 

Hardware & Equipment Interfaces 

• Support sustaining activities for load boards, probe cards, and interface hardware; conduct schematic reviews and updates as necessary. 
• Collaborate with hardware design teams on engineering changes, hardware robustness, and long-term maintainability. 
• Assist production sites and equipment engineering teams with tester, handler, and hardware troubleshooting. 

Continuous Improvement 

• Drive cost-reduction initiatives through test time optimization, hardware improvements, and flow enhancements. 
• Support standardization of test methods, documentation practices, and equipment usage across global test centers. 
• Contribute to cross-functional improvement programs aligned with quality, cost, and operational targets. 

Documentation & Compliance 

• Prepare and maintain technical reports, engineering change notices, test specifications, and validation records. 
• Ensure all sustaining activities are aligned with corporate quality systems, safety standards, and reliability expectations. 

What you will need

• Bachelor’s or Master’s degree in Electronic Engineering or equivalent discipline. •
• Proven experience in sustaining or production test engineering within the semiconductor industry. 
• Strong knowledge of Analog and Logic IC devices; experience with power management ICs is advantageous. 
• Proficiency in C/C++ or equivalent programming languages used in ATE environments. 
• Practical experience with semiconductor ATE platforms (ETS88, ETS364, Magnum preferred). 
• Ability to interpret PCB schematics; PCB or circuit design experience is beneficial. 
• Strong analytical, diagnostic, and problem-solving skills. 
• Customer-oriented mindset with a strong understanding of the impact of test performance on manufacturing and product quality. 
• Effective communication skills in written and spoken English. 
• Familiarity with lab equipment (oscilloscope, function generator, curve tracer) is an advantage. 
• Demonstrated technical aptitude and strong troubleshooting capability.
• Ability to work collaboratively with cross-functional and cross-cultural teams. 
• Self-motivated, proactive, and able to work independently with minimal supervision. 
• Strong ownership and accountability with a continuous improvement mindset.
