Silicon Photonics Test Development Engineer

About the Role

New College Graduate position within the GF Test Development organization supporting Silicon Photonics (SiPh) semiconductor technologies for high-speed data center, high-performance computing, and hyperscale computing applications. This engineer will develop and improve automated optical and electrical test solutions used to characterize photonic integrated circuits (PICs), analyze device performance, and support reliable technology development and product qualification.

Key Responsibilities

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

Requirements & Tech Stack

• 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.
• English (Written & Verbal) Fluency.
• Advanced programming experience in a Linux environment using Python and C/C++; experience with R or Perl is a plus.
• Foundational knowledge of silicon photonics, optical and electrical device characterization, high-speed or mm-wave circuits, statistics, and experimental test methodology.
• Hands-on laboratory, capstone, or research experience is preferred.
• Prior related internship or co-op experience is preferred.
• Demonstrated prior leadership experience is preferred.
• Strong interest in leveraging AI tools and emerging technologies is preferred.
• Project management skills are preferred.
• Strong written and verbal communication skills.
• Strong planning & organizational skills.
