About 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.

As part of our growth and to meet the increasing needs of our R&D, we are actively seeking an Embedded Software Engineer to strengthen our team.
