Job DescriptionJob Description

Key Responsibilities:

  • Design, model, and optimize silicon photonic devices, including grating couplers, waveguides, SOAs, and photodetectors, for high-speed AI computing applications.
  • Collaborate with external foundries to develop manufacturable designs using process design kits (PDKs) and ensure successful tape-out of silicon photonic components.
  • Perform design-for-manufacturing (DFM) and design-for-test (DFT) evaluations to ensure scalability and robust production.
  • Conduct and interpret optical simulations using industry-standard tools (e.g., Lumerical, Ansys, COMSOL, or equivalent).
  • Work with optical fiber assemblies and ensure seamless integration with high-speed photonic systems.
  • Perform experimental validation and characterization of silicon photonic devices in the lab.
  • Lead design reviews and contribute to the development of optical test plans, specifications, and manufacturing guidelines.
  • Support the development of intellectual property (IP) and contribute to patent filings related to novel silicon photonic designs.
  • Mentor junior engineers and contribute to the continuous improvement of silicon photonics design methodologies.

Qualifications:

  • PhD in Photonics, Physics, Electrical Engineering, or a related discipline.
  • Minimum of 10 years of industry experience in silicon photonics design, development
  • Demonstrated expertise in designing and optimizing photonic integrated circuits, including grating couplers, waveguides, SOAs, and photodetectors.
  • Proven track record of taking silicon photonic devices from concept through to commercial production using leading foundries.
  • Hands-on experience working with PDKs, performing DFM/DFT, and managing tape-outs.
  • Experience characterizing and validating silicon photonic devices in a laboratory environment.
  • Familiarity with optical fiber coupling and high-speed photonics applications.
