Responsibilities

• Troubleshoot and diagnose PCBA, server, and system-level hardware failures in a high-volume manufacturing environment.
• Analyze failures identified during functional, in-circuit, system-level, and production testing.
• Perform failure isolation and root cause analysis using schematics, board layouts, test results, logs, and diagnostic tools.
• Work with Test Engineering and Manufacturing Engineering teams to identify recurring failure trends and implement corrective actions.
• Develop and maintain diagnostic procedures, troubleshooting guides, and failure analysis documentation.
• Utilize electrical test equipment such as oscilloscopes, multimeters, power supplies, logic analyzers, and other diagnostic equipment.
• Analyze system logs, test data, error codes, and hardware telemetry to identify potential failure points.
• Troubleshoot communication and hardware interfaces including PCIe, USB, I2C, SPI, UART, Ethernet, and other relevant protocols.
• Support server-level troubleshooting involving CPUs, memory, storage devices, power supplies, motherboards, networking components, and peripheral hardware.
• 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.

Qualifications

• 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.
