🚀 About Us

At baCta, we are reimagining industrial biotechnology for a more sustainable future. One of our strategic R&D ambitions is the development of microbial strains capable of producing natural rubber (polyisoprene) through fermentation, as an alternative to traditional extraction from rubber trees or synthetic rubber production from oil.

We’re a small, ambitious, and highly technical team working at the intersection of biology, chemistry, and engineering. If you want to build the process that makes cutting-edge science become an industrial reality — this role is for you.

🎯 Your mission

Your mission will be to contribute to the development and optimization of our extraction and analytical pipeline for polyisoprene produced by engineered microorganisms. This process is key to evaluating the impact of strain engineering and fermentation strategies on natural rubber production.

Concretely, you will:

• Extract and purify polymers of interest from microbial cultures (100+ samples/week)
• Learn and run analytical methods like NMR and SEC (with expert guidance)
• Scale the extraction process from microplates to 2L fermentations
• Collaborate with the strain engineering, fermentation, and analytics teams
• Optimize and document protocols with scientific rigor

🔬 What You'll Learn & Use

• Research and development in a fast-moving startup
• State-of-the-art analytical tools (NMR, SEC, etc.)
• High-throughput workflow design and process troubleshooting
• Yeast microbiology, downstream extraction, and natural product chemistry
• Scientific communication in an R&D context
