Full Job Description
Job Summary:

We are seeking a creative and hands-on Silicon Photonics Engineer to drive the design and implementation of next-generation photonic integrated circuits. This role spans the full development cycle of silicon photonic devices and subsystems, from device concept generation and electromagnetic simulation to physical layout, tapeout support, and design verification. The ideal candidate is comfortable moving between theoretical modeling and practical implementation, with strong intuition for both photonic device physics and layout realization within foundry process constraints. Particularly, this position is focusing on efforts for complex switching circuit application.

Responsibilities:
  • Interacts with device, hardware, and system design teams to assist in overall development of photonic systems and devices.
  • Supports foundry tape outs with photonic device design, design of experiments, layout, design verification, PDK development, and software development.
  • Develops comprehensive documentation for tapeouts.
  • Provides multi-disciplinary support to component and systems teams by resolving technical issues associated with components, parts, or systems.
  • Applies quantitative analysis in determining root cause of highly technical problems and proposes, develops, and implements solutions for corrective action.

Experience/Qualifications:
  • Education: PhD or equivalent in Electrical Engineering or Physics.
  • Experience:
    • 5 years of relevant work or academic research experience in integrated photonics.
  • Knowledge, Skills and Abilities:
    • Strong computational and analytical skills applied to photonic device design and performance evaluation.
    • In-depth knowledge of photonic devices, including performance metrics and testing techniques.
    • Extensive experience with photonic design using commercial software platforms such as Lumerical simulation suite.
    • Photonic layout experience using tools such as IPKISS, gdsfactory, or equivalent.
    • Extensive experience with Python for scientific applications and data analysis.
    • Excellent communication skills and the ability to collaborate effectively across technical and non-technical teams.
