Your Team, Your Impact

The CPO Apps team operates at the intersection of optics, high-speed electrical design, advanced packaging, and system architecture, providing hands-on technical support and successfully enabling customer adoption of Co-Packaged Optics at scale.

What You Can Expect

• Act as the primary technical interface for strategic customers designing CPO into GPUs, accelerators, and scale-up platforms
• Lead customer architecture reviews, design-in engagements, and deep-dive technical discussions
• Translate system-level customer requirements into complete CPO solutions spanning optics, electrical, mechanical, thermal, and test
• Support bring-up, characterization, debug, and qualification of CPO-based designs. Lab skills are a must.
• Provide clear technical guidance, trade-off analysis, and risk mitigation throughout the customer design cycle
• Drive end-to-end CPO solution definition, including:
• Optical engines and silicon photonics integration
• High-speed electrical interfaces (112G+, die-to-die, advanced SerDes)
• Signal integrity, power delivery, thermal, and packaging constraints
• Mechanical integration into GPU or accelerator packages
• Support host system integration, including board-level, cooling, and manufacturing considerations
• Perform hands-on lab-level test, characterization, debug, and failure analysis of CPO systems

Technical Demo Lead & Owner for Optical Industry Events
