At En Carta Diagnostics, we believe molecular diagnostics should be faster, more accessible, and closer to where care begins.

We are developing a new generation of point-of-need diagnostic devices with a bold ambition: turn every smartphone into a PCR machine, and bring better diagnostics everywhere.

Our first product, EC POCket Lyme, is designed to help detect Lyme disease early, directly at the tick bite, through a unique test intended for use close to the patient. And this is only the beginning: more products are already in development.

As we grow and strengthen our R&D team, we are hiring across complementary roles in scientific research, hardware and software development, and laboratory operations. As part of this broader team build, we are looking for a Senior Scientist - Molecular & Synthetic Biology to join us in Paris.

We are a purpose-driven company, guided by strong values : evidence-based · integrity · responsibility · sustainability

Why are we hiring

En Carta is entering a new phase of development, with EC POCket Lyme progressing toward industrialization and additional products in development. We are expanding our R&D team to strengthen scientific depth, experimental execution, and product development capabilities.

In this role, you will help drive ambitious research projects forward while contributing to the development of next-generation diagnostic products.

What the role is about

This role is for someone who wants to do excellent science and see it move toward real-world impact.

You will own and drive projects within the broader scientific priorities set by the R&D leadership. You will combine deep expertise in molecular or synthetic biology with a strong experimental mindset and solid computational skills. You will stay close to the bench, mentor junior colleagues, and help translate cutting-edge biology into practical diagnostics.

This role is ideal for someone with postdoctoral-level scientific maturity who wants to lead at the project level while experimentally active. Wanting to be at the bench is a must have.

You will report to the Head of R&D and work closely with the broader multidisciplinary R&D team.
