Senior Electro-Optical Test Engineer

Shape rigorous electro-optical testing at Inpho through PAM4 measurements, equipment calibration, and defensible characterization methodology.

This Senior Electro-Optical Validation Engineer leads validation for Inpho’s next-generation InP-based optical components and photonic chips. You will own device-level testing, from measurement configuration through technical sign-off. The position requires practical knowledge of lasers, modulators, detectors, and optical networking testing.

Key Responsibilities:

• Define repeatable methods separating device performance from equipment artifacts
• Own high-speed equipment configuration, calibration, troubleshooting, and vendor interactions
• Configure EAM, EML, and PD measurements across pad geometries
• Analyze S-, Y-, and Z-parameter representations and extract alignment values
• Collaborate with design and test teams on device troubleshooting

Requirements:

• Eight-plus years of hands-on optical networking or related engineering experience
• Experience with IMDD and PAM4 testing and InP component characterization
• Proficiency debugging high-speed test equipment and developing Python analysis
• Knowledge of semiconductor laser, modulator, and detector operation
• Exceptional analytical judgment and attention to detail

Bring electro-optical testing leadership, calibration discipline, PAM4 expertise, and semiconductor device knowledge to Inpho’s validation work.
