• Develop and enhance physics-based models describing plasma-surface interactions, surface chemistry, material transport, and profile evolution.
• Translate physical theories, experimental observations, and mathematical models into robust, production-quality software.
• Collaborate with plasma physicists, process engineers, computational scientists, and product teams to improve model fidelity and predictive capability.
• Develop numerical algorithms for geometry evolution, particle transport, surface reaction kinetics, and related multiphysics phenomena.
• Optimize simulation performance for modern computing architectures, including multicore CPUs and GPU-based systems.
• Validate model predictions against experimental and metrology data.
• Contribute to software architecture, testing frameworks, code reviews, and engineering best practices.
• Investigate emerging approaches including machine learning, surrogate modeling, and digital twin technologies to accelerate simulation workflows.
• Publish technical results and contribute to patents, conference presentations, and scientific publications when appropriate.

Required qualifications

• Ph.D. or M.S. in Physics, Computational Science, Applied Mathematics, Electrical Engineering, Chemical Engineering, Materials Science, Computer Science, or related technical discipline.
• Familiarity developing feature-scale, topography, or process simulation tools for plasma etch and deposition
• Strong software development experience in C++ and Python
• Experience developing numerical simulation or scientific computing software.
• Understanding of computational methods such as:
  • Monte Carlo techniques
  • Numerical optimization
  • Finite difference or finite element methods
  • Particle transport simulations
  • Geometry evolution algorithms
  • Multiphysics modeling
• Ability to work effectively across both physics and software domains.
• Strong analytical and problem-solving skills.
