About the Role
You will lead the development of an internal photonic process design kit. You will build and maintain Python-based layout libraries, create compact behavioral models, automate parameter extraction from electromagnetic solvers, correlate models with lab measurements, and implement verification workflows for PDK updates.
Requirements
- Master’s degree with 5+ years of experience or PhD with 3+ years of experience in Electrical Engineering, Photonics, Physics, or a related field
- Deep understanding of photonic device physics and device simulation
- Experience building behavioral models for circuit simulators
- Experience using Python for modeling, automation, and data analysis
- Object-oriented programming experience with NumPy and SciPy
- Python-based layout experience
- Capacity to comply with federally mandated U.S. export control laws
Responsibilities
- Develop and maintain a library of pcells using Python-based layout frameworks
- Synchronize physical layouts, logical netlists, and behavioral models
- Create and verify behavioral compact models for passive and active devices
- Build automated workflows to extract electromagnetic-solver parameters for circuit-level simulation
- Validate simulation models against lab measurements using data fitting and statistical analysis
- Implement regression testing and continuous integration pipelines for PDK updates
- Own netlist-extraction logic and connectivity-graph accuracy
Benefits
- Comprehensive medical, dental, and vision coverage
- Retirement savings matching program
- Life insurance, including basic, voluntary, and AD&D coverage
- Vacation, sick time, and public holidays
- Paid family leave
- Short-term and long-term disability coverage
- Commuter benefits
