About the role
We are seeking a highly skilled System Application Engineer (Hardware) to support next-generation AI networking platforms and high-speed optical interconnects. In this role, you will work closely with customers deploying 800G and 1.6T optical transceivers on 51.2T-class and emerging switch architectures, with a strong emphasis on hardware bring-up, lab validation, interoperability testing, and system-level debug .
What they're looking for
- Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, Physics, or a related field
- Strong understanding of optical transceivers, including module architectures, control interfaces, configuration protocols, and performance metrics
- Extensive hands-on experience with DSP tuning, optical transceiver configuration, and high-speed link bring-up and debug
- Deep familiarity with AI networking switch architecture, host electrical interfaces, and system-level integration of optical modules
- Hands-on experience with lab equipment such as oscilloscopes, BERTs, VNAs, protocol analyzers, or similar tools used for hardware validation
- Experience working with 800G modules, 1.6T architectures, or 51.2T switches is highly desirable
