$58,400 - $100,800 USD yearly
Originally posted 16 October 2026 by the employer.
About the role
This New College Graduate position supports Silicon Photonics (SiPh) semiconductor technologies for high-speed data center, high-performance computing, and hyperscale computing applications within the GF Test Development organization.
What you'll do
- Develop, execute, and document optical and electrical test plans for silicon photonic integrated circuits.
- Perform device and circuit characterization, including DC current-voltage (I-V), capacitance-voltage (C-V), optical insertion loss, and electro-optic bandwidth measurements.
- Own and improve high-speed test methods using vector network analyzers, optical power meters, tunable lasers, and oscilloscopes.
- Analyze large characterization datasets using AI and statistical methods to identify trends, outliers, and correlations.
- Troubleshoot hardware, software, and data-quality issues, communicating results in technical reviews.
- Partner with cross-functional teams to improve test coverage, throughput, and measurement capability.
What you'll need
- Graduating with a Bachelor’s in Physics, Electrical Engineering, Computer Science, Photonics, Optical Engineering, or a related field.
- Overall 3.0 GPA and proven good academic standing.
- Fluency in English (written and verbal).
Nice to have
- Prior related internship or co-op experience.
- Advanced programming experience in a Linux environment using Python and C/C++; experience with R or Perl.
- 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.
- Strong interest in leveraging AI tools and emerging technologies.
- Project management skills.
- Strong planning and organizational skills.
