About the Company
We’re partnering with a global leader in semiconductor manufacturing equipment that enables the production of advanced integrated circuits used in consumer electronics, cloud computing, and artificial intelligence.
This organization designs and manufactures cutting-edge plasma etch, deposition, and cleaning systems used by major semiconductor companies worldwide. Their engineering teams push the boundaries of plasma physics, chemistry, and materials science to support next-generation chip manufacturing.
Position Overview
The company’s Reactor-Scale Modeling team is seeking a Computational Chemistry Modeling Engineer to support ongoing development of its plasma reactor simulation capabilities. The team recently implemented a new computational chemistry platform (Quantemol-EC) to improve how gas-phase reaction chemistry is represented within its reactor-scale models.
This position is ideal for someone with experience in computational chemistry, plasma physics, or multiphysics simulation who enjoys bridging fundamental reaction data with real-world reactor behavior.
Key Responsibilities
- Operate Quantemol-EC (or similar software) to calculate electron impact cross-sections for plasma process chemistries.
- Analyze and validate computed data using literature, experimental, or published cross-section data.
- Collaborate with reactor modeling engineers and plasma scientists to integrate chemistry data into reactor-scale plasma simulations.
- Perform data analysis, validation, and documentation of cross-section datasets and modeling results.
- Support R&D efforts to enhance the predictive accuracy of plasma process models used in semiconductor tool design.
???????Required Skills
- Proven experience with Quantemol-EC, Quantemol-P, or similar computational chemistry or plasma modeling software.
- Strong background in computational chemistry, physics, plasma science, or chemical engineering.
- Understanding of electron-molecule interactions, gas-phase kinetics, or reaction rate modeling.
- Proficiency in data analysis, scripting, and scientific computing (Python, MATLAB, etc.).
- Excellent problem-solving and communication skills; able to present complex results clearly to cross-functional teams.
Preferred Qualifications
- Advanced degree (MS or PhD) in Chemistry, Physics, Chemical Engineering, or Materials Science.
- Prior experience in plasma etch, deposition, or reactor modeling within the semiconductor or materials processing industries.
- Familiarity with R-matrix methods, DFT/MD simulations, or molecular modeling of gas-phase reactions.
- Experience with COMSOL Multiphysics, ANSYS Fluent, CFD-ACE+, or other reactor-scale simulation platforms.
- Understanding of semiconductor plasma systems, thin-film processing, or vacuum-based manufacturing environments.
Why Join This Team
- Work on cutting-edge plasma modeling initiatives that directly impact semiconductor technology advancement.
- Collaborate with a multidisciplinary R&D group combining chemistry, physics, and engineering expertise.
- Gain exposure to reactor-scale plasma modeling, simulation tool development, and process design innovation used by top chipmakers worldwide.
- Contribute to next-generation plasma reactor design and help shape the future of semiconductor fabrication.
