🎯 Mission of the Internship

As a Molecular Biology intern, you will contribute to the design, construction, and evaluation of engineered microbial strains capable of producing pigments with industrial potential. You will work as part of an agile, multidisciplinary R&D team and participate in iterative cycles of design-build-test-learn (DBTL).

You will be involved in:

  • Constructing and validating expression cassettes and biosynthetic pathways
  • Testing strain variants for pigment production
  • Integrating results with fermentation and analytics data to inform engineering strategies

🧪 Your Main Tasks

  • 🧬 Molecular biology: cloning, plasmid assembly, transformation, genome editing
  • 🧫 Strain construction: selection, genotyping, pathway validation
  • 🌱 Mini-scale culture assays to assess growth and pigment production
  • 📊 Data analysis: interpretation of screening results and troubleshooting
  • 🤝 Collaboration with fermentation and analytics teams to align strain performance with process needs

📚 What You'll Learn

  • Application of synthetic biology to the biosynthesis of natural pigments
  • Use of tools such as Benchling, Python, and version-controlled strain libraries
  • Experimental design in high-throughput microbial engineering workflows
  • Exposure to an industrial R&D process focused on sustainability and scalability

✅ Your Profile

  • Enrolled in a Master 2 or final-year engineering program in biotechnology, synthetic biology, or microbial engineering
  • Strong foundation in molecular biology and microbial genetics
  • Prior lab experience with cloning and microbial culture is essential
  • Familiarity with natural product biosynthesis or pigment pathways is a plus
  • Motivated, curious, and excited to work in a fast-paced research environment
  • Fluent in English

🌟 Why Choose baCta?

  • Be part of a mission-driven startup developing next-gen sustainable ingredients
  • Work in a fast-paced Paris-based biotech startup with a collaborative culture
  • Contribute directly to strain design with measurable downstream impact
  • Learn from experienced scientists in bioengineering, fermentation, and analytics
  • Participate in shaping early-stage strain engineering workflows in an industrial setting

⭐ Benefits

  • Health insurance (Alan) 100% covered
  • Lunch voucher of 12€/day (7€/day paid by the company), 2 team lunches per month
