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.
Location:
Remote
Anticipated Contract Length:
12+ months
Start Date:
January 5, 2026
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.
TSG is an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or status as a protected veteran.
