Senior Optical Engineer bei Focused

About Focused Energy

At Focused Energy, we are developing NeoLyte, a breakthrough initiative that pioneers compact, laser-driven radiation sources (LDRS) based on high-power laser technology. These dual-mode sources combine MeV X-rays and fast neutrons in a single system. The platform is modular and enables real-time, non-destructive inspection of materials, even when those that are complex or shielded. NeoLyte’s technology addresses critical challenges across nuclear waste analysis, contraband detection, infrastructure inspection, and medical isotope production. With its unique combination of resolution, material specificity, and deployment flexibility, LDRS open up new possibilities far beyond conventional systems. We bring together a cross-disciplinary team of laser and plasma physicists, engineers, and AI experts. We are building our first pilot facility in Biblis (Germany), with the goal to reach market readiness and commercial deployment quite soon. Be part of shaping this deep-tech venture from the ground up!
