Co-Founder — Laser–Materials Processing / Materials Physics

Join to apply for the

Co-Founder — Laser–Materials Processing / Materials Physics

role at

Lprint .

LPRINT is a French deep‑tech start‑up, supported by

INRIA, X‑Up (École Polytechnique) . We are developing an

innovative 3D printer for the additive manufacturing of industrial‑grade multilayer printed circuit boards (PCBs) .

Our mission is to

transform the way PCBs are designed and manufactured, enabling faster, more flexible, and sustainable PCB production that empowers hardware engineers and product development teams .

Our system enables

high‑precision, multi‑material printing

of conductive and dielectric materials — bridging the gap between laser processing, materials science, and electronics fabrication.

Your Role You will lead the

materials and process development

side of the technology:

Study and optimize

laser–matter interaction mechanisms

for materials;

Develop and characterize

functional materials

suitable for our method printing (conductive, dielectric);

Define and refine process parameters;

Collaborate closely with the optics / electronics co‑founder to integrate process insights into the printing system;

Contribute to the

design of experiments (DoE)

and prototype validation cycles;

Support IP development, publications, and potential industrial collaborations;

Coordinate collaboration with chemical partners, labs, and universities.

Required Qualifications

PhD in

Materials Science, Applied Physics, Laser Processing, or Physical Chemistry ;

Hands‑on experience with

pulsed lasers (ns/ps/fs) ;

Previous work in

printed electronics

as a plus;

Entrepreneurial mindset and interest in building a deep‑tech start‑up in the

Île‑de‑France

ecosystem;

Based in Île‑de‑France (or willing to relocate) for regular on‑site sessions at the Drahi‑X Novation Center;

Proficiency in English (written and spoken) for scientific and technical communication.

What You’ll Get

Co‑founder equity and leadership role in an early‑stage deep‑tech start‑up;

Work on the frontier of

optics, materials, and advanced manufacturing ;

Shape the next generation of

additive electronics manufacturing .
