What You’ll DoWe 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.
