• Validation of high‑speed optical and electrical interfaces (optical lanes, SerDes, PCIe, Ethernet). Experienced with:

• NRZ/PAMx BER testing and eye diagram analysis

• Link margining and stress testing

• Standard compliance point testing

• De-embedding SI effects of high-speed interconnects

• Experience validating optical electrical devices used for data center optical modules and high‑speed interfaces such as TIAs, Drivers and Equalizers

• Familiarity with relevant standards is highly regarded

• Validation and design verification of TIA performance, including:

• Bandwidth, gain, noise, linearity, and stability

• Sensitivity and overload behavior

• Jitter and signal‑to‑noise impacts on optical data paths

• Experience correlating test results to design simulation results

• Strong understanding of end‑to‑end system architecture, spanning optical front ends, high‑speed electrical interfaces, firmware, drivers, and operating systems

• Ownership of validation activities across DVT, PVT and debug activities

• Defining the Hardware requirements and be able to run debugging of hardware-firmware-DUT

• Development and ownership of automated validation frameworks for validation plan of record

• Strong scripting skills in C#, MATLAB, Python

• Automation of test execution, data capture, result analysis, and reporting
