Lead end-to-end validation and characterization of Optical Engines integrating EIC and PIC in multiple Silicon Photonic architectures.
Develop comprehensive test plans, methodologies, and automation frameworks for optical, electrical, and electro-optical performance metrics (e.g., BER, eye diagrams, insertion loss, extinction ratio, receiver sensitivity, transmitter power).
Perform detailed characterization of key building blocks: modulators, photodetectors, lasers, waveguides, couplers, and high-speed EIC/PIC interfaces.
Validate co-packaged optics performance including high-speed electrical interfaces (SerDes, UCIe), thermal management, signal integrity, power integrity, and optical coupling efficiency.
Design and implement test setups for wafer-level, package-level, and system-level testing, including active alignment, thermal cycling, reliability stress, and environmental qualification.
Collaborate closely with PIC Design, EIC Design, Packaging, Test Engineering, and Manufacturing teams to close design-for-test (DfT) and design-for-manufacturability (DfM) gaps.
Analyze large datasets from validation runs, perform failure analysis, root cause investigation, and drive corrective actions.
Support bring-up and debug of silicon photonics prototypes and optical modules.
Define and execute qualification plans per industry standards (Telcordia, GR-468, JEDEC, etc.).
Mentor junior engineers and contribute to intellectual property through patents and technical publications.
Qualifications & Requirements
Master's or PhD in Electrical Engineering, Optical Engineering, Photonics, Physics, or related field.
8+ years (Senior) to 12+ years (Principal) of hands-on experience in silicon photonics or optical transceiver validation.
Strong experience with EIC/PIC co-design validation, multiple Optical Configurations.
Expertise in high-speed optical and electrical testing: BER testers, sampling oscilloscopes, VNAs, spectrum analyzers, tunable lasers, optical power meters, and automated test equipment.
Proficiency with photonic test automation (Python, LabVIEW, or equivalent) and data analysis tools (JMP, MATLAB, Python/Pandas).
Deep understanding of optical coupling, thermal effects in 2.5D/3D packaging, and high-speed signal integrity challenges in CPO systems.
Familiarity with industry standards for reliability and qualification of photonic components.
