Failure Analysis Engineer

The role

You will lead investigations of optical, electrical, and mechanical failures in optical transceiver products. You will use schematics and test equipment to identify root causes and drive corrective actions through collaboration with R&D, supplier quality, and production teams.

What you will do

• Perform optical, mechanical and electrical analysis/troubleshooting of optical transceivers.
• Troubleshoot failures using schematics, test equipment, switches, fault isolation techniques, and Design of Experiments.
• Work with cross-functional teams to determine root causes and corrective actions.
• Document all test and failure analysis results including photographs, test data, and repair work.
• Interface with production databases to extract shipment, test, and traceability information.
• Assess field risk based on failure modes and field data.
• Analyze and present updates on failure analysis progress and reliability estimates.
• Engage in discussion with customers and respond to technical inquiries.
• Bring-up new internal and external test infrastructure.
• Develop test scripts to operate and report data from customer switches.

Required qualifications

• Minimum 5 yr. experience of related experience.
• BS/MS in physics, electrical/Mechanical engineering or other relevant field or equivalent experience.
• Extensive knowledge of and experience working with analog and digital circuits.
• Familiar with MSA and customer standards/requirements.
• Familiar with basic failure analysis techniques/methodologies.
• Strong device physics background.
• Fundamental understanding of OSA assembly and its periphery circuits.
• Working knowledge of device characterization and its techniques.
• Strong data analysis skills.
• Excellent verbal and written communication skills.

Nice to have

• Experiences in transceiver module tests at 400G, 800G, 1.6T, etc.
• Knowledge of OSA assemblies, PCBA, and module manufacturing processes is an added advantage.
• Experience in datacenter architecture is a plus
