Associate Failure Analysis Engineer

The role

You will investigate optical, electrical, and mechanical failures in optical transceiver products. You will use schematics and test equipment to identify root causes and drive corrective actions.

What you will do

• Analyze optical, mechanical and electrical failures of optical transceivers from field deployment or internal testing
• 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 to R&D, corporate teams, and customers
• Engage in discussion with customers and respond to direct technical inquiries
• Bring-up new internal and external test infrastructure
• Develop test scripts to operate and report data from customer switches

Required qualifications

• Bachelor’s or Master’s degree in optics, optical engineering, physics, electrical engineering, mechanical engineering, or a closely related field
• Knowledge of analog and digital circuits
• Familiarity with MSA and customer standards/requirements
• Basic failure analysis techniques/methodologies
• Strong understanding of device physics
• 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

• Experience with or an academic background in optical components, photonics, or electronic systems
• Knowledge of OSA assemblies, PCBA, and module manufacturing processes
• Experience in datacenter architecture
