Lumilens is building critical photonics infrastructure for AI supercomputing, including chip-to-chip optical interconnects and scalable photonic engines. The company is Series B-funded and led by veterans from transformative technology companies.
As an Associate Failure Analysis Engineer, you will investigate optical, electrical, and mechanical failures in advanced optical transceiver products from field deployments and production testing. You'll use schematics, test equipment, fault isolation techniques, and Design of Experiments to identify root causes and drive corrective actions.
Key responsibilities include:
- Troubleshooting failures in optical transceivers using schematics, test equipment, switches, and fault isolation techniques
- Working with cross-functional teams (supplier quality, R&D, production) to determine root causes and corrective actions
- Documenting all test and failure analysis results with photographs, test data, and repair work
- Extracting and analyzing production databases for shipment information, test data, and traceability
- Assessing field risk based on failure modes and field data using reliability tools
- Presenting periodic updates on failure analysis progress and reliability estimates to R&D, corporate teams, and customers
- Engaging directly with customers on technical inquiries
- Bringing up new internal and external test infrastructure to validate failure signatures
- Developing test scripts to operate and report data from customer switches
This is a hands-on, collaborative role at the intersection of engineering, quality, and innovation, ideal for someone passionate about problem-solving and continuous improvement in optical technologies.
REQUIREMENTS:
- Bachelor's or Master's degree in optics, optical engineering, physics, electrical engineering, mechanical engineering, or closely related field
- Experience with or academic background in optical components, photonics, or electronic systems (preferred)
- Knowledge of analog and digital circuits
- Familiarity with MSA and customer standards/requirements
- Basic failure analysis techniques and methodologies
- Strong understanding of device physics
- Fundamental understanding of OSA assembly and its periphery circuits
- Knowledge of OSA assemblies, PCBA, and module manufacturing processes (added advantage)
- Working knowledge of device characterization and its techniques
- Strong data analysis skills
- Excellent verbal and written communication skills
- Experience in datacenter architecture (plus)
