Built with GPU-accelerated simulation, high-throughput automation, and advanced visualization, it empowers researchers to explore the vast molecular landscape with ease.
About the Role
We’re seeking a Senior Computational Materials Scientist to join the development of the Molecular Universe and participate in simulation efforts related to solid electrolyte interphase (SEI) modeling, chemical reaction simulation, force field development, and molecular dynamics acceleration on large-scale HPC systems.You’ll collaborate with other computational materials scientists, AI engineers, software developers, and experimental teams to build tools that bridge quantum chemistry, statistical mechanics, and machine learning for real-world molecular discovery.
Key Responsibilities
- Design and run large-scale quantum chemistry and molecular dynamics simulations (e.g., GPU4PySCF, GROMACS, LAMMPS, Gaussian).
- Develop or refine interatomic potentials/force fields tailored to electrolyte systems.
- Develop, implement, and refine tooling to investigate SEI formation, including chemical reaction network pipelines and atomistic simulations.
- Contribute to property calculation workflows for quantum descriptors (HOMO, LUMO, ESP), thermodynamics, and kinetics.
- Automate high-throughput simulations with Python, HPC schedulers (e.g., SLURM), and distributed computing.
- Integrate new simulation capabilities into our Molecular Universe platform via APIs or modular Python packages.
Qualifications
Required:
- PhD in Materials Science, Chemistry, Chemical Engineering, Physics, or related field.
- 5+ years of post-PhD experience in computational chemistry/materials (academic or industry).
- Hands-on expertise with molecular simulation tools such as GROMACS, LAMMPS, Gaussian, VASP, Quantum Expresso, ADF, GPU4PySCF, or equivalent.
- Strong coding skills in Python, including scientific stack (NumPy, ASE, PySCF, etc.), and experience with developing research-grade code.
- Familiarity with high-throughput computation and large-scale data analysis on HPC or GPU clusters.
- Strong communication skills and ability to work cross-functionally with experimental and AI teams.
Preferred Experience:
- Experience with battery materials, solid/liquid interfaces, or electrolyte development.
- Prior work on force field parameterization, reactive MD (Polarizable FF, ReaxFF, MLFF), or coarse-grained methods.
- Familiarity with cheminformatics concepts, including molecular representations (SMILES strings, fingerprints, etc.) and chemical space traversal.
- Contributions to open-source tools or published methods in molecular simulation or AI/ML
- Familiarity with unsupervised machine learning, including dimensionality reduction techniques and clustering algorithms beyond k-means.
- Experience with CUDA programming
