Seeking a Research Scientist or Postdoctoral Researcher (26-1964)

Research Scientist Or Postdoctoral Researcher

The RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is focused on advancing high-end computational science through three main objectives: the “Science of Computing,” the “Science by Computing,” and the “Science for Computing.”

The Materials Science Application Interface Platform Development Unit is recruiting research employees to carry out a new theme. The research overview of the laboratory is shown below. Our main target is as follows:

• Development of Molecular Software and Theory through Foundation Models
• 1) Engineering of systems based on large language models to automatically generate quantum chemistry software components for use on FugakuNEXT. Creation of methods for automatic software documentation, validation, and optimization specifically for high-performance computing.
• 2) Use of multimodal models to generate hypotheses for new quantum chemistry methods or studies. Development of an Artificial Intelligence agent driven loop of hypotheses formulation, code generation, deployment, analysis, and visualization for molecular science.

Job title: Research Scientist or Postdoctoral Researcher: 1 position

Position-specific tasks are as follows:

Research Scientist
Conduct research projects and other activities in corresponding laboratories.
Postdoctoral Researcher
Receive training and guidance from senior staff; conduct research projects and other activities for corresponding laboratories.

The recruited researcher will carry out a project supported by JST ARiSE projects. Their assigned work directly contributes to the Materials Science Application Interface Platform Development Unit's research on integrating Large Language Models and Agentic AI into materials science research.

The overall goal of the ARiSE project is to develop a foundation model for materials science. To this end, the creation of large datasets of high-quality materials simulations is essential. However, typical high throughput simulation work treats electronic structure methods as a black box, leading to datasets of uneven or even questionable quality. The primary purpose of this subtheme will be to develop agents able to automatically utilize multiple simulation codes and theories, while making the dynamic decisions required for high fidelity results. The researcher will also collaborate with members of the larger project towards the development of practical datasets and models. The researcher will further build and optimize the software components required for high-quality results to be generated efficiently on HPC platforms.

External Fund: JST ARiSE “Development of Materials-AI Platform for 'AI for Materials'” The project funding period is 30 October 2026–31 March 2029.
