Position Scope
SES AI is seeking a Computational Chemistry Interns to join the Molecular Universe team and support computational modeling and simulation of advanced electrolyte systems. This is a hands-on research role focused on liquid-phase molecular dynamics (MD) simulations, especially for electrolyte systems relevant to next-generation batteries.
Interns will receive training and mentorship from our computational scientist, and collaborate across global teams.
Location: U.S. Eastern Time Zone (Remote)
Candidate must be based in the U.S. East Coast region to support business operations.
Duration: 6 months

Requirements

• PhD (or PhD candidate) in Computational Chemistry, Materials Science, Chemical Engineering, Physical Chemistry, or a related field
• Hands-on experience with molecular dynamics simulations, particularly for liquid-phase systems
• Familiarity with common simulation tools such as GROMACS, LAMMPS, OPENMM, or similar packages
• Understanding of molecular force fields, including basic principles of force field development and parameterization; direct experience is preferred
• Programming skills in Python or similar languages for data analysis, workflow automation, and simulation pipeline development
• Strong problem-solving skills and the ability to diagnose simulation instability, convergence issues, and physical inconsistencies
• Excellent communication skills, with the ability to clearly present technical findings to both technical and non-technical audiences
• Ability to work effectively in a collaborative, international research environment
• Professional English proficiency is required, including technical discussions, documentation, and presentations

Nice To Haves

• Experience with electrolyte systems, ionic systems, battery-related simulations, or sodium-ion systems is strongly preferred

Responsibilities

• Contribute to the SES Molecular Universe project by supporting computational chemistry modeling and simulation of advanced electrolyte systems
• Independently or collaboratively perform molecular dynamics simulations for liquid-phase systems, especially electrolytes, including system construction, initial structure generation, and simulation parameter setup
• Execute the full MD workflow, including job submission, HPC resource utilization, run monitoring, troubleshooting, and issue resolution
• Analyze simulation results in depth, including but not limited to: Structural properties such as radial distribution functions (RDF), coordination numbers, and solvation structures Dynamic properties such as diffusion coefficients and ion transport behavior Thermodynamic and statistical property extraction
• Build and improve automated data-processing pipelines to enhance simulation efficiency, reproducibility, and scalability
• Convert simulation outputs into clear reports, visualizations, and presentations that support scientific and engineering decision-making
• Collaborate with internal teams to improve workflow robustness and reproducibility across simulation pipelines
• Support the scaling and engineering of molecular simulation workflows within the MU platform
• Contribute to force field development, optimization, and validation for electrolyte or ion-containing systems
• Explore higher-accuracy or higher-efficiency simulation methodologies
• Participate in the engineering and platformization of simulation workflows, including workflow automation, orchestration, and task scheduling

Benefits

• Work on real, high-impact problems in next-generation battery materials discovery
• Contribute to production-relevant simulation workflows rather than isolated academic projects
• Gain exposure to the intersection of molecular simulation, automation, AI for Science, and materials innovation
• Collaborate with a global team across simulation, machine learning, and experimental validation
