• Develop and validate physics-based models for chemical reactions, reaction kinetics, gas-phase chemistry, and surface reactions.
• Conduct reacting-flow simulations and coupled thermal, fluid, mass transfer, and chemical kinetics analyses.
• Support simulation-driven design and optimization of gas delivery systems, thermal management solutions, process equipment, and advanced materials.
• Calibrate and validate models using experimental data and engineering principles.
• Analyze results, identify design improvements, and support troubleshooting and root cause analysis.
• Prepare technical reports and presentations with modeling results and engineering recommendations.
• Collaborate with cross-functional engineering and technical teams.

Required Qualifications

• Master’s or Ph.D. in Chemical Engineering, Mechanical Engineering, Aerospace Engineering, Chemistry, Plasma Physics, or a related field.
• Strong experience with CFD and multiphysics simulations.
• Experience with chemical reaction modeling, reaction kinetics, reacting-flow CFD, or species transport.
• Strong knowledge of fluid mechanics, thermodynamics, heat transfer, mass transfer, and gas flow dynamics.
• Excellent analytical, communication, and technical presentation skills.

Preferred Simulation Tools

• ANSYS Fluent – Strong Preference
• STAR-CCM+
• COMSOL Multiphysics
