Staff Photonics Design & PDK Modeling Engineer

Job summary

Responsibilities

If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.

• Develop and maintain a library of pcells using Python-based frameworks. Ensure strict synchronization between physical layout, logical netlists, and behavioral models.
• Create and verify physics based behavior models for passive and active devices.
• Design test structure, develop test plans for device FOMs extraction. Work with test engineers to get silicon data.
• Validate models against lab measurements. Perform data fitting and statistical analysis to align model parameters with real-world silicon performance.
• Automated Verification: Implement regression testing and Continuous Integration (CI) pipelines to ensure PDK updates do not break legacy designs or connectivity logic.

What they're looking for

• Master’s +5 years experience or PhD +3 years experience in Electrical Engineering, Photonics, Physics, or related field.
• Deep understanding of photonic device physics and experience in device simulation.
• Experience building behavioral models for circuit simulators (e.g., Lumerical INTERCONNECT, Cadence, Synopsys OptSim, or custom Python solvers).
• Experienced in Python for modeling, automation, and data analysis. Comfortable with object-oriented programming and scientific libraries (NumPy, SciPy).
• Python based layout experience.
