About this role

This full-time machine learning engineer role is part of the research and development team for Oishi Kenko’s food and health services. The team works to improve service value with machine-learning models and to build academic evidence for the effectiveness of the company’s services.

The position may also involve academic research activities, including opportunities to contribute to papers and conference presentations.

Basic statistics knowledge, including tests and multiple regression, is required. The posting also requires at least one year of practical experience selecting appropriate data-analysis methods for business or client issues, together with a focus on maintainable, usable code and documentation.

Experience with Ruby or Rails, mobile application development, or infrastructure operations using cloud platforms such as AWS is welcomed.
