• Develop, execute, and document optical and electrical test plans for silicon photonic integrated circuits, including automated instrument control, test sequencing, data acquisition, and analysis in a Linux environment using Python and C/C++.

• Perform device and circuit characterization, including DC current-voltage (I-V), capacitance-voltage (C-V), optical insertion loss, waveguide loss, wavelength response, fiber-to-chip coupling efficiency, photodetector responsivity, modulator transfer characteristics, and electro-optic bandwidth measurements.

• Own and improve high-speed test methods using vector network analyzers, optical power meters, tunable lasers, oscilloscopes, optical spectrum analyzers, stimulus and measuring units, probe stations, and RF/optical probes; support calibration, de-embedding, correlation, measurement repeatability, and uncertainty evaluation.

• Analyze large characterization datasets using AI, statistical methods to identify trends, outliers, correlations, and sources of variation; troubleshoot hardware, software, and data-quality issues, communicate results in technical reviews, and partner with cross-functional teams to improve test coverage, throughput, and measurement capability.

Other Responsibilities:

• Perform all activities in a safe and responsible manner and support all Environmental, Health, Safety & Security requirements and programs.

Required Qualifications:

• Education – Graduating with Bachelor’s in Physics, Electrical Engineering, Computer Science, Photonics, Optical Engineering or related field from an accredited degree program. 

• Must have at least an overall 3.0 GPA and proven good academic standing.

• Language Fluency - English (Written & Verbal) 

Preferred Qualifications: 

• Prior related internship or co-op experience.

• Demonstrated prior leadership experience in the workplace, school projects, competitions, etc.
