• Review schematics, PCB layouts, BOMs, and engineering specifications to support failure investigation.
• Collaborate with Quality and Engineering teams to identify root causes and implement corrective and preventive actions.
• Track failure data and identify trends related to specific components, processes, test stations, suppliers, or manufacturing conditions.
• Support production lines by providing timely technical assistance for complex or recurring failures.
• Participate in engineering builds, new product introductions, process improvements, and production readiness activities.
• Work with suppliers and component manufacturers as needed to investigate component-related failures.
• Assist in the development and improvement of automated and manual diagnostic processes.
• Provide technical guidance and training to technicians and production personnel on troubleshooting procedures.
• Maintain accurate records of failure analysis, diagnostic results, corrective actions, and engineering recommendations.
• Follow all company safety, quality, and manufacturing procedures.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Electronics Engineering, or a related field preferred.
• 2+ years of experience in electronics, PCBA, server, computer hardware, manufacturing, test engineering, or failure analysis.
• Strong understanding of electronic circuits, digital systems, PCBA components, and computer/server architecture.
• Experience troubleshooting hardware failures at the board and/or system level.
• Experience using electrical diagnostic equipment such as oscilloscopes, multimeters, logic analyzers, and power supplies.
• Ability to read and interpret electrical schematics, PCB layouts, engineering drawings, and technical specifications.
• Knowledge of PC/server hardware, including CPUs, memory, storage, networking, power systems, and peripheral devices.
• Familiarity with hardware communication protocols such as PCIe, I2C, SPI, UART, USB, and Ethernet.
• Experience with failure analysis and root cause analysis methodologies.
• Ability to interpret test logs, error codes, diagnostic results, and manufacturing data.
• Strong analytical and problem-solving skills with the ability to troubleshoot complex technical issues.
• Experience working in a high-volume manufacturing or production environment preferred.
• Familiarity with automated test equipment, functional testing, ICT, FCT, or system-level testing preferred.
• Experience with Linux and/or Windows operating systems preferred.
• Basic scripting or programming experience using Python, C/C++, Shell, or similar languages is a plus.
• Strong written and verbal communication skills.
• Ability to work cross-functionally with Engineering, Quality, Manufacturing, Test, and Production teams.
• Ability to work onsite in a fast-paced manufacturing environment.
• Bilingual English/Mandarin is a plus.
