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 driven Junior Product Development Engineer – Hardware & Computational Systems to join us in Paris.
We are a purpose-driven company, guided by strong values : evidence-based · integrity · responsibility · sustainability
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 improve our hardware platform, support computational workflows, and contribute practical software and AI-enabled tools that help the team move faster.
This is a hands-on engineering role at the intersection of hardware, software, and product development.
You will contribute to the refinement and optimization of En Carta’s hardware platform for EC POCket Lyme and future products, while also supporting computational developments and practical AI-enabled process improvements across the team.
This is a junior role, but not a narrow one. It is a great fit for an engineer who enjoys building and improving real products, has already shown initiative through internships or documented projects, and wants to grow in a fast-moving startup environment where technical curiosity, versatility, and ownership matter.
You will be supported by a multidisciplinary team and are not expected to arrive as an expert in every aspect of the role.
You will work within the R&D team at the interface of hardware, software, and product development, in close collaboration with scientists and product stakeholders.
You will report to the Head of R&D and work closely with the broader multidisciplinary R&D team.
