The ideal candidate will have experience in optical module integration, high-speed PAM4 systems, optical communication standards, performance troubleshooting, and cross-functional problem-solving.

Hands-on experience with optical transceiver testing across EVT, EDVT, DVT, ODVT, and FVT phases is preferred.

Key Responsibilities

• Develop and execute R&D test plans for high-speed optical modules throughout EVT, EDVT, DVT, ODVT, and customer qualification phases.
• Perform integration debugging and performance optimization of optical modules.
• Lead module-level performance tuning by correlating optical and electrical measurements, DSP status, register settings, telemetry data, and system-level results.
• Define, review, and maintain test plans, test specifications, test cases, validation reports, and debug documentation.
• Perform system-level validation involving optical modules, switches, traffic testers, reference modules, optical fibers, and test equipment.
• Apply relevant optical communication standards and specifications, including IEEE 802.3 Ethernet standards and CMIS 5.2/5.3 management specifications.
• Lead design of experiments (DOE), performance optimization, and root-cause analysis in collaboration with optical, hardware, DSP, firmware, system, supplier, manufacturing, and quality teams.
• Support the selection, procurement, installation, calibration, and validation of test equipment, fixtures, and R&D test stations.
• Support customer sample testing, ODVT data preparation, customer issue analysis, and technical report generation.
• Serve as the test owner or test lead for assigned programs, track test progress and open issues, and proactively drive project milestones to completion.

Desired Knowledge and Qualifications

• Master’s degree with 3+ years of experience, or Bachelor’s degree with 5+ years of experience, in optical communications, optical module development, high-speed electronics, or R&D testing.
• Strong understanding of optical module architecture and key components, including lasers, PICs, TOSA, ROSA, DSPs, drivers, TIAs, SerDes, MPDs, and module management interfaces.
• Experience with optical module integration, performance debugging, parameter tuning, and system-level optimization.
• Ability to read and interpret test specifications, register definitions, technical documentation, and product requirements.
• Strong capabilities in test planning, test data analysis, failure reporting, and technical documentation.
• Experience with Python, JMP, Excel, or other data analysis and test automation tools is preferred.
• Strong communication, coordination, learning, and analytical problem-solving skills.
• Good English proficiency, equivalent to CET-6 or above, including reading, speaking, and writing.

Desired Characteristics

• Curious about innovative technologies and motivated to develop strong technical expertise.
