Senior Signal Integrity Engineer - Optical Transceivers & LPO Modules

Position Summary

We are seeking an experienced Signal Integrity Engineer, Optics, to join our High-Speed I/O R&D team. The successful candidate will be responsible for the electrical design, simulation, validation, and optimization of next-generation optical transceivers, Linear Pluggable Optics (LPO), and high-speed networking products supporting 800G, 1.6T and future generation applications. This role requires deep expertise in high-speed serial channels, DSPs, retimers, SerDes architectures, PCB design, cable assemblies, optical modules, and signal integrity analysis from concept through production.

Responsibilities

• Evaluate optical engine integration, TIA, laser driver, VCSEL, EML, and photodiode interfaces.
• Collaborate with Firmware engineering, software engineering, mechanical teams.
• Analyze insertion loss, return loss, crosstalk, impedance discontinuities, and channel compliance.
• Hands-on optical transceiver, LPO module qualification with broader system integration is a plus.
• Support compliance testing and customer qualification activities.
• Evaluate and optimize channels utilizing DSPs, retimers, and high-speed SerDes devices.
• Analyze CTLE, DFE, FFE, adaptive equalization, FEC, and link margin performance.
• Knowledge of Co-Packaged Optics (CPO) is a plus.
• Develop optical transceivers and LPO products.
• Understand NIC architectures and networking protocols including Ethernet, TCP/IP, PCIe, and MCTP.
• Participate in performance optimization of complete networking systems.

Required Qualifications

• BS, MS, or PhD in Electrical Engineering or related field.
• 5+ years of experience in high-speed signal integrity engineering.
• Strong understanding of high-speed serial interfaces and networking systems.
• Experience with 56G, 112G, and preferably 224G PAM4 technologies.
• Experience developing optical transceivers and LPO products.
