Job Description
What You’ll Do
We are seeking a highly skilled and motivated Senior Optical System Engineer to join ourhardware engineering team focused on next-generation AI/datacenter optical interconnect technologies. In this role, you will lead the design, development, validation, qualification, and optimization of advanced optical sub-systems including silicon photonics PICs, optical engines, high-speed DSP-based optical links, and 1.6T/3.2T optical Interconnects.
The ideal candidate will have strong expertise in optical systems, CPO/OCI architectures, system-level interoperability, high-speed optical/electrical characterization, automated test development, and optical system qualification. This role requires close collaboration with photonics, DSP/ASIC, SI/PI, packaging, firmware, and manufacturing teams to support the development and production ramp of scalable, high-performance, and power-efficient optical interconnect solutions for hyperscale AI infrastructure.
Key Responsibilities:
• Lead system-level design validation and qualification of advanced optical interconnect products including 1.6T/3.2T optical interconnect, silicon photonics PICs, optical engines, DSP-based optical links, and CPO/OCI systems.
• Develop and execute comprehensive validation plans for optical modules, high-speed electrical and optical interfaces, switch-level interoperability, and rack-level system qualification.
• Characterize and optimize key optical and electrical performance metrics including BER, TDECQ, jitter, OSNR, extinction ratio, receiver sensitivity, eye quality, link margin, and power efficiency.
• Perform module-level, simulation-level, and system-level qualification testing for IMDD and coherent optical systems.
• Lead high-speed optical and electrical debug activities for PAM4 links operating at 200G/lane, 400G/lane, and beyond.
• Develop, automate, and maintain optical/electrical test stations using Python, MATLAB, LabVIEW, and database-driven analytics tools.
• Collaborate closely with photonics, DSP/ASIC, SI/PI, packaging, firmware, manufacturing, and system architecture teams to optimize overall system performance and manufacturability.
• Support optical architecture development for AI clusters, XPO/LPO/LRO systems, co- packaged optics, optical switching systems, and optical compute fabrics.
• Contribute to industry standards activities including IEEE 802.3, OIF, CMIS, and MSA specifications.
• Analyze test results and generate detailed technical reports to support design reviews, customer qualification, and production deployment.
