Paid internship or alternance 6 months minimum Sorbonne University, Jussieu · Paris From September 2026

Paid internship or alternance, six months minimum. Help build, optimise and screen a set of strains for the bio-electrochemistry experiments that produce our nitrogen fertilizers. Hands-on lab work alongside the founding team on a high-impact project.

WHY SYNANTHRA

What you would be working on

A problem worth solving

Nitrogen fertilizer production today depends entirely on the Haber-Bosch process, which runs on natural gas and accounts for 2.1% of global greenhouse gas emissions.

A different approach

We replace that process with a bioelectrochemical platform: a genetically engineered microorganism that fixes nitrogen directly from air, water and green electricity.

Close to the founders

We are a small, early-stage start-up. You work directly with the founding team, see your results feed straight into the platform, and take real ownership once trained.

Don't see the right position?

We are always glad to hear from scientists and engineers who want to help replace the Haber-Bosch process. Send us your CV and a short note about what you would like to work on.
