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.

Our system enables high-precision, multi-material printing of conductive and dielectric materials — bridging the gap between laser processing, materials science, and electronics fabrication.

We are looking for a Co-Founder with deep expertise in laser–materials interaction and materials physics to join the founding team and help bring this breakthrough process from lab to prototype and beyond.

🎯 Your Role

You will lead the materials and process development side of the technology:

• Lead printed electronics process development: laser-based deposition
• Study and optimize laser–material interaction for functional materials
• Develop and characterize conductive, dielectric, and functional materials
• Define process parameters and design of experiments (DoE); drive prototype validation cycles
• Collaborate with the optics/electronics co-founder on system integration
• Build and manage partnerships with chemical suppliers, academic labs, and industrial collaborators
• Contribute to IP development, publications, and grant applications

🔬 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 startup 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 a leadership role in an early-stage deep-tech startup
• Work at the frontier of laser processing, printed electronics, and advanced manufacturing
• Shape the next generation of additive PCB manufacturing
