## Job description

Introduction Are you passionate about computational physics, optical modeling, and solving complex scientific challenges? As a Optical Modeling and Simulation Engineering Intern, you will contribute to advanced research in optical metrology and sensor technologies that support the continued innovation of semiconductor manufacturing systems. The Optical Modeling and Simulation Engineering Intern role offers an opportunity to work on cutting-edge problems involving nano-optics, photonics, and computational electromagnetics.

You will collaborate with researchers and engineers developing advanced simulation and optimization methodologies used to model light-matter interactions at sub-wavelength scales. Through this internship, the Optical Modeling and Simulation Engineering Intern will gain hands-on experience applying numerical methods, scientific computing, and optimization techniques to real-world engineering challenges. This position is ideal for students interested in combining physics, computation, and software development to advance next-generation optical technologies.

Role and Responsibilities As a Optical Modeling and Simulation Engineering Intern, you will support research and development activities focused on optical simulation, numerical modeling, and computational optimization. You will work with multidisciplinary teams to investigate new concepts, validate methodologies, and improve simulation capabilities. Develop advanced computational methods and software capabilities for optical simulation and optimization.

Create and enhance numerical models that characterize light-matter interactions at nanometer scales. Design and perform simulation studies to evaluate new concepts and quantify performance improvements. Analyze simulation data and interpret technical results using scientific and engineering principles. Collaborate with researchers and engineers to solve complex optics and photonics challenges. Document technical findings and communicate results through reports, presentations, and technical discussions.

Contribute to research initiatives and innovation projects supporting future optical metrology technologies.

### Education and Experience

Currently pursuing a master's degree or PhD in Physics, Applied Physics, Electrical Engineering, Optics, Photonics, or a related technical field. Experience through research, coursework, publications, or academic projects involving optics, photonics, or computational physics.
