• Collaborate with internal and external teams in fabrication, testing, packaging, electronics and system designs.

Requirements:

• PhD in electrical engineering, optics, applied physics, materials science, or a closely related field.
• Strong understanding of integrated optics, electromagnetic theory, and semiconductor-device fundamentals.
• Experience with optical simulation methods and tools.
• Experience with photonic-device layout and familiarity with semiconductor fabrication processes.
• Ability to use Python, MATLAB or similar software for data analysis and automation.
• Hands-on experience with optical and electro-optical test equipment.
• Clear written and verbal communication skills.
• Ability to work effectively in a multidisciplinary engineering environment.
  Preferred Qualifications
• Three years of relevant experience following completion of the PhD.
• Experience designing modulators, photodetectors, wavelength filters, or optical transceivers on silicon photonic platform.
• Familiarity with CMOS-compatible fabrication and tapeout experience with commercial foundries.
• Experience with RF probes, vector network analyzers, high-speed oscilloscopes, or bit-error-rate testing.
• Knowledge of compact modeling, statistical variation, or design-for-manufacturing methods.
• Experience in automating measurement systems.
  Open to candidates anywhere in the United States; the San Francisco Bay Area is preferred. Remote work may be considered.
