The Opportunity

Introduction to the team: The Batteries vertical sits at the intersection of ChemSim and AI Simulation, where SandboxAQ uses physics-based simulation, proprietary datasets, and Large Quantitative Models (LQMs) to discover and optimize next-generation battery materials. Our goal is to compress slow, empirical battery R&D into an AI-driven workflow spanning prediction, simulation, and materials discovery for high-impact applications including solid-state batteries, Cobalt-free cathodes, beyond Li-ion cell chemistries, and resilient energy storage systems.

Introduction to the role: We are seeking a highly skilled Research Scientist in Materials Simulation to join our dynamic team. The ideal candidate will have a strong background in applying advanced simulation techniques, particularly Density Functional Theory (DFT) and Molecular Dynamics (MD), to battery materials. Additionally, expertise in building, fine-tuning or optimizing AI models for chemistry and material discovery.

Key Responsibilities

• Conduct advanced simulations using DFT and MD for solid-state materials, with a focus on predicting properties for solid-state electrolytes and interfacial degradation reactions.
• Employ data-driven approaches to analyze large datasets derived from computational simulations and experiments to uncover new insights into materials behavior.
• Conduct high-fidelity data generation campaigns and develop ML force fields for solid-state materials.
• Guide and scope projects with clear deliverables alongside agile teams.
• Collaborate closely with multi-disciplinary teams to independently prototype and scale cutting-edge, impactful materials design solutions.
• Generate and evaluate hypotheses to assist design decisions and influence project direction by developing and deploying computational methods and workflows.
• Effectively present and communicate research findings through scientific talks, blog posts, client-oriented presentations, and peer-reviewed publications.

Essential Skills & Experience

• Ph.D. in Materials Science, Chemical Engineering, Chemistry, Computer Science, or a related field is preferred.
• 3+ years of hands-on experience in modeling complex solid-state battery materials, such as cathodes, anodes, solid-state electrolytes, and/or interfacial reactions at non-equilibrium states is highly desirable.
• Proficiency in common DFT and MD simulation software (e.g., VASP, Quantum ESPRESSO, LAMMPS, ASE).
• Experience with developing or using AI models for chemistry and material discovery using popular deep learning frameworks on CPUs and GPUs.
• Proven ability to benchmark and compare domain specific AI models for materials discovery.

Highly Desired Skills & Experience

• Contributions to open-source projects related to MLIPs.
• Authorship of publications in high impact peer-reviewed journals or conferences.
• Demonstrated ability in project leadership within an industrial setting, including managing teams, timelines, and deliverables.
