About this position

Symbiobe Co., Ltd. is recruiting for a researcher / postdoc-equivalent R&D position in microbial research, scale-up, functionality evaluation, and application development. The role is based in Kyoto, Japan (Kyoto City, Nishikyo Ward, Kyoto University Katsura Venture Plaza South Building) and is part of a bio-startup working on the social implementation of microbial technologies.

The company focuses on turning underutilized regional resources into industrially usable resources through microorganisms, with development spanning basic research, cultivation-condition establishment, scale-up, production, and application expansion. The post emphasizes hands-on work in uncertain, implementation-stage challenges such as reproducibility, process stabilization, and cost balancing, while collaborating across research, production, and quality functions.

Research keywords: microbial culture, bioprocess, bio-manufacturing, functional evaluation, application development, scale-up, QA/QC, and industrial implementation. The company also mentions collaboration with partner companies in energy, materials, livestock, fisheries, and food-related projects.

Eligibility highlights: a bachelor's degree is required; applicants should have R&D experience in a science field, a track record of iterative troubleshooting when experiments fail, and experience independently setting problems and pushing them forward through hands-on work. Preferred experience includes microbial culture, bioprocessing, analysis, scale-up-oriented development, QA/QC basics, and English reading/communication.

Employment and funding: this is a permanent full-time position with no fixed term and a probationary period. Salary is listed at 4.0–6.0 million yen annually (example monthly salaries of 400,000–500,000 yen), with transportation support and potential stock options. Social insurance is provided.

Application window: applications are accepted until 2026-12-31, though the posting says it will close once the right candidate is found. Apply by email or through the JREC-IN web application portal with a resume and work history/CV.

What's required
