Key responsibilities:
- Develop Automation Scripts: Create robust, reusable scripts to automate the setup, execution, and data extraction of commercial electrical and optical simulation tools.
- Integrate Tools: Design and implement seamless workflows connecting various simulation tools and the overall design environment.
- Apply Machine Learning: Investigate and implement machine learning models (e.g., surrogate models, Bayesian optimization, or reinforcement learning) to efficiently navigate large design spaces and propose optimal chip architectures or device parameters.
- Optimize Performance: Identify bottlenecks in current simulation workflows and develop strategies to reduce simulation time and computational cost.
- Documentation: Clearly document all developed code, workflows, and machine learning methodologies.
Qualifications:
- Current Enrollment: Currently pursuing a B.S. or M.S in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
- Programming Proficiency: Expert-level proficiency in Python for scripting, data analysis, and automation.
- EDA Scripting: Proven experience or strong willingness to learn and use Cadence SKILL programming for layout and simulation environment customization.
- Simulation Tools: Familiarity with commercial EDA (Electronic Design Automation) and PDK (Photonic Design Kit) simulation tools (e.g., ADS, Cadence Spectre/Virtuoso).
- Machine Learning Fundamentals: A solid foundation in machine learning concepts, including model training, validation, and practical experience with relevant libraries (e.g., NumPy, Pandas, scikit-learn, TensorFlow/PyTorch).
- Experience with version control systems (e.g., Git).
Preferred:
- Currently pursuing a graduate degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
- Prior experience with electrical integrated circuit (EIC) and/or photonic integrated circuit (PIC)
- Familiarity with cloud computing environments for running large-scale simulations.
- Familiarity with with Signal integrity and power integrity simulation tools such as Cadence Sigrity, ANSYS HFSS/SIWave and IDEM
