Photonic Mixed Signal Design Validation Engineer

Job Title

Photonic Mixed Signal Design Validation Engineer

Role Summary

Validate and debug co-packaged optics (CPO) photonic and mixed-signal silicon builds. Work with cross-functional teams to develop test methods, characterize optical, electro-optical, RF, and analog performance, and provide actionable feedback to designers.

This role focuses on hands-on lab validation, test automation, and performance margin analysis for new photonic mixed-signal products.

Experience Level

Entry-level / Early career — expects about 2+ years of experience in measuring, analyzing, and debugging mixed-signal builds.

Responsibilities

Primary responsibilities include hands-on validation, characterization, and interfacing with design and test teams.

• Develop validation test methods for new photonic mixed-signal chip builds.
• Characterize optical, electro-optical, RF, and analog performance of new builds at die and module level.
• Validate, debug, and characterize analog, photonic, electrical-optical, and mixed-signal designs.
• Provide detailed feedback to designers on silicon performance, build quality, and design margins.
• Verify electrical-optical compliance to industry standards and test plans.
• Coordinate with multifunctional teams (design, test, manufacturing) to support chip development and validation cycles.
• Write and maintain scripts and tools for validation, data analysis, and test automation.

Requirements

Required technical skills, tools, and traits. "Nice-to-have" items listed separately.

• Must-have: Deep understanding of fundamental optical components and analog circuits.
• Must-have: RF testing experience at die or module level and detailed knowledge of optical lab equipment.
• Must-have: Experience with scripting and data analysis (Python, Git, Matlab, or JMP) and ability to automate test flows.
• Must-have: Proven ability to measure, analyze, and debug complex mixed-signal builds in a lab environment.
• Must-have: Strong collaboration skills and ability to communicate technical findings to designers.
• Nice-to-have: Experience with control loops and optical transceiver performance testing at high data rates.
• Nice-to-have: Working knowledge of wafer probe test systems and wafer handling.
• Nice-to-have: Familiarity with industry electrical-optical compliance standards.

Education Requirements

Master of Science in Electrical Engineering, Physics, Computer Engineering, or equivalent practical experience.
