About the role
Job Details: Job Description: The Principal Optical Sub-System Architect will help drive the revolution to photonic interconnect for high performance data centers. The exceptional candidate will understand and help optimize Optical systems bridging between optical capabilities and data center needs. Bandwidth, power, latency, cost trade-offs for optical vs electrical system design including understanding optical packaging, optical thermal issues, connectors, fiber assembly techniques, rack considerations (bend radius), back-plane, front-plane access concerns, manageability and training techniques. Knowledge of LPO vs DWDM and CWDM trade-offs is critical. Candidate should be able to translate customer
requirements (latency, power, footprint and BW) to product
requirements and system design. As the future is driving toward co-packaged optics, the candidate should have experience and understanding of how co-packaged optics will contribute to the future data center while intersecting with traditional electrical systems and switching networks. Understanding photonic standards as well as networking standards. Key
Responsibilities: Optical Architecture Leadership • Define and drive optical subsystem architecture for the next generation data center. • Design scalable optical hierarchies, including CPUs, GPUs and electrical switches. • Deep knowledge of Packaging optics and the future issues of co-packaged Optics. Performance and Efficiency Optimization • Develop strategies for bandwidth optimization, latency reduction, and power efficiency. • Analyze trade-offs between capacity, throughput, and cost for hyperscale deployments. Protocol Design • Analysis and recommendations on UAL, UEC, SUE, and proprietary protocol mechanisms and standards. • Technical understanding and analysis capability of PHY components (UCIe, 802.3xx (over SMF and twinax), OIF) • Ensure consistency and reliability across heterogeneous environments. Modeling and Simulation • Build analytic performance models for Optical subsystems and validate through simulation. • Conduct workload characterization for AI, HPC, and cloud applications. Cross-Functional Collaboration • Work closely with CPU architects, interconnect designers, and software teams to ensure seamless integration. • Partner with vendors. Innovation and Research • Explore emerging optical technologies (uLED and others). • Drive R-and-D initiatives for future-proof optical solutions in large-scale data centers. Leadership and Mentorship • Provide technical guidance to engineers and influence architectural decisions across teams. Additional Skills: • Strong leadership and strategic thinking abilities. • Excellent communication skills for technical and executive audiences. • Ability to influence architectural decisions across multiple teams
