Entry Level Modeling Simulation Engineer information
What is the difference between Entry Level Modeling Simulation Engineer vs Mechanical Design Engineer?
| Aspect | Entry Level Modeling Simulation Engineer | Mechanical Design Engineer |
|---|---|---|
| Required Credentials | Bachelor's in Mechanical, Aerospace, or related fields; basic knowledge of simulation software | Bachelor's in Mechanical or Aerospace Engineering; CAD and design software skills |
| Work Environment | Research labs, engineering teams, simulation software environments | Design studios, manufacturing facilities, engineering departments |
| Employer & Industry Usage | Automotive, aerospace, defense, manufacturing companies | Product design firms, manufacturing companies, R&D departments |
While both roles require a background in mechanical engineering and involve technical skills, the Entry Level Modeling Simulation Engineer focuses on creating and analyzing virtual models using simulation software, whereas the Mechanical Design Engineer emphasizes designing physical components and systems. Both roles are essential in product development but differ in their primary tasks and tools used.

Job description
We are hiring a Photonics PDK Modeling Engineer to join our team. In this role, you will lead the development of our internal Process Design Kit (PDK). You will act as the architect of our component library, bridging the gap between physical device physics and system-level simulation. You will develop robust compact models for active and passive components, ensuring that our simulation environment accurately predicts the behavior of our physical layouts. You will work heavily in Python, applying software engineering rigor to the challenges of photonic hardware design.
Responsibilities- Develop and maintain a library of pcells using Python-based layout frameworks. Ensure strict synchronization between physical layout, logical netlists, and behavioral models.
- Create and verify behavioral compact models for passive and active devices
- Simulation Infrastructure: Build automated workflows that extract parameters from electromagnetic solvers (FDTD/FEM) and package them into the PDK for circuit-level simulation.
- Model-Hardware Correlation: Validate simulation 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.
- Netlist & Connectivity: Own the logic for netlist extraction, ensuring that the connectivity graph generated by the code perfectly matches the physical intent.
- 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.
- Familiarity with GDSFactory, OptoCompiler, or KLayout Python scripting.
- Experience with Python-native circuit simulation ecosystems (e.g., SAX, Photontorch, Simphony).
- Experience with Git version control, unit testing (pytest), and CI/CD workflows.
- Prior experience in performing physical layout using foundry-provided process design kits (PDKs), adhering to specific design rules and constraints.
- Experience in taping out and testing large-scale photonic integrated circuits, including familiarity with relevant testing equipment and methodologies.
- Experience doing inverse design
- Possess strong project execution skills, demonstrating the ability to effectively manage multiple design priorities, adhere to project timelines, and meet critical milestones.
