Tech Lead Optical Test Engineer

The ideal candidate has solid experience in optical testing, strong problem-solving skills, and the ability to collaborate across teams to enable efficient characterization, validation, and production testing.

Key Responsibilities

• Define and implement optical test architectures and test flows across optical wafer probe test, package level test & characterization and optical module validation.

• Execute characterization and qualification testing of CPO components and assemblies.

• Perform high-speed optical measurements including insertion loss, return loss, extinction ratio, eye diagram analysis, BER testing, and optical modulation amplitude (OMA).

• Characterize optical performance parameters such as wavelength accuracy, channel spacing, spectral linearity, and crosstalk for WDM-based CPO architectures.

• Design and build optical test stations incorporating fiber alignment systems, optical switches, tunable lasers, optical spectrum analyzers, high-speed oscilloscopes, and BER testers.

• Develop test automation software, automated test scripts & frameworks using Python, LabVIEW, MATLAB, or similar platforms.

• Implement high-throughput test solutions suitable for wafer-scale and production-level testing.

• Analyze large-scale optical test data to identify trends, failure modes, and yield-limiting factors.

• Generate statistical reports (Cpk, GR&R, SPC) to monitor process stability and test repeatability.

• Collaborate with design and process engineering teams to provide feedback for performance optimization.

• Create and maintain test documentation, SOPs, and knowledge base articles.

• Interface with external suppliers and foundries on silicon photonics wafer-level test requirements.

• Participate in design reviews to ensure testability and provide DFT (Design for Test) recommendations.

Required Qualifications

• M.S. or Ph.D. in Electrical Engineering, Optical Engineering, Physics, Photonics, or a related discipline.

• 5–7+ years of experience in optical testing, photonic device characterization, or optical transceiver development.

• Strong understanding of silicon photonics devices (modulators, photodetectors, multiplexers, grating couplers, edge couplers).

• Hands-on experience with optical test equipment: OSA, OMA, tunable lasers, polarization controllers, power meters, high-speed real-time oscilloscopes, BERT/pattern generators.

• Proficiency in high-speed optical link testing (100G/lane and above, PAM4, NRZ).

• Programming skills in Python, MATLAB, LabVIEW, or C/C++ for test automation.

• Knowledge of optical communication standards (IEEE 802.3, OIF-CEI, CMIS).

• Familiarity with statistical analysis methods and data visualization tools.

Preferred Qualifications

• Experience specifically with co-packaged optics or on-board optics architectures.

• Experience with wafer-level optical probing and testing tool hardware & software as well as automated photonics test platforms.

• Experience in transitioning test processes from lab/prototype to high-volume manufacturing (HVM).

Salary range is $185,000 to $240,000 depending on experience, level, and business need. This role may be eligible for discretionary bonus, incentives and benefits.
