What We Offer

- Highly competitive salary and robust benefits, including comprehensive health coverage and attractive equity/stock options in a NYSE-listed company.

- The opportunity to contribute directly to a meaningful scientific mission: accelerating the global energy transition with clear and broad public impact.

- A dynamic, collaborative environment at the intersection of AI, computational science, and advanced battery technology.

- Significant opportunities for growth as you collaborate with leading experts in AI, R&D, and engineering.

Role Overview

We are seeking a Product Engineer to architect and lead our AI-driven molecular simulation and materials informatics platform for next-generation battery materials.

This leader will bridge advanced AI model architectures with computational chemistry, molecular dynamics (MD), and phase-field simulation, designing and scaling the scientific computing platforms and toolchains that power SES AI’s materials discovery and battery R&D.

 

You will support the productization of AI4Science capabilities—from ML force fields and surrogate models to automated MD workflows—turning them into robust, developer-friendly APIs and platforms used across SES’s global R&D organization.

Key Responsibilities

Platform & Architecture

- Lead the end-to-end design of a scientific computing platform for battery materials, integrating AI/ML models, experimental data, and cloud infrastructure.

- Architect and implement high-performance computing (HPC) and C++-based simulation services for large-scale MD, phase-field, and related materials models.

- Define and evolve the API architecture and platform interfaces that expose simulation, ML, and data services to internal users and tools.

 

AI-Driven Materials Simulation & Automation

- Drive development and deployment of AI/ML models for materials informatics, including ML force fields, surrogate models, and uncertainty-aware prediction pipelines.

- Build and manage MD automation systems and simulation toolchains that scale across thousands of runs, integrating job scheduling, monitoring, and data management.

- Translate research prototypes (e.g., new ML models for materials, dendrite growth algorithms) into reliable, production-grade services.

 

Battery R&D Integration

- Work closely with battery scientists, electrochemists, and experimentalists to map R&D needs into platform features and workflows.

- Develop simulation and algorithmic capabilities focused on battery dendrite growth, degradation mechanisms, and electrolyte/material performance.

- Ensure tight integration of simulation and AI outputs with experimental workflows, data pipelines, and informatics dashboards.

 

Core Competencies

- C++ and high-performance/scientific computing

- HPC systems and parallel computing (MPI, CUDA, GPU acceleration, or similar)

- Molecular dynamics (MD) simulation and related tools/workflows

- API engineering and large-scale platform architecture

- Battery informatics and AI4Science for materials

- MD workflow automation & simulation toolchain design

- Hybrid expertise in scientific computing + modern software engineering

Minimum Qualifications

- PhD in Materials Science, Computational Physics, Computational Chemistry, or a closely related field.

- 1+ years (post-graduate) of experience in computational materials science, including molecular dynamics and/or phase-field simulation.

- Proven track record building production-grade scientific software in C++ and/or similar systems languages, ideally in an HPC context.

- Hands-on experience with AI/ML for materials informatics, such as ML force fields, surrogate models, or automated ML workflows.

- Demonstrated experience designing and implementing APIs, services, and platforms used by other engineers or scientists.

- Strong background in algorithm development related to materials behavior (e.g., dendrite growth, transport, microstructure evolution).

- Experience collaborating closely with experimentalists and domain scientists and translating their needs into robust engineering solutions.

Preferred Qualifications

- Experience building or leading AI4Science platforms (e.g., integrating simulation, ML, and lab/experimental data into unified systems).

- Prior ownership of cloud-native scientific computing platforms (Kubernetes, containers, workflow engines, etc.).

- Background in battery R&D (Li-metal, Li-ion, electrolytes, interfaces) and associated multiscale modeling.

- Experience leading product engineering or platform engineering teams, especially in deep-tech or R&D-heavy environments.

- Familiarity with modern data and ML stacks (Python, PyTorch/JAX/TensorFlow, feature stores, model registries, workflow orchestration).
