Senior Photonics Link Verification Engineer

Lead high-speed electro-optic link verification at Lightmatter, combining photonics expertise with hands-on laboratory characterization and debug.

This senior Photonics Engineer owns verification across multiple silicon and system programs. You will develop channel models, correlate measurements, and address signal integrity and link-performance challenges. The work spans optical hardware, electrical hardware, SerDes, and silicon bring-up.

Key Responsibilities:

• Characterize and debug high-speed electrical and optical hardware
• Build channel models and correlate bench measurements
• Own link budgets and verification methodology
• Analyze eye diagrams, BER, jitter, and equalization
• Support silicon bring-up and root-cause investigations

Requirements:

• MS or PhD with eight-plus years, or BS/MS with ten-plus years
• Verification strategy ownership for a complete silicon or system program
• Expertise in 56G, 112G, or 224G-plus serial links
• Strong Python or MATLAB automation experience
• Proficiency with VNAs, oscilloscopes, BERTs, TDRs, and modeling tools

Apply photonics, SerDes, signal integrity, and measurement expertise to Lightmatter’s advanced AI infrastructure programs.
