Laser Plasma Physicist (AIML)

About the Company & Role :

Focused Energy is the leading laser-driven fusion company pursuing the most promising path to clean limitless fusion power. The global company based in Darmstadt Germany and the San Francisco Bay Area has brought together the top scientific and engineering minds using proven technologies to unlock fusion power at commercial scale.

At Focused Energy we are not only aiming for long term game changing solutions but are also solving near term challenges with global impact. We are developing SourceLight a breakthrough initiative that pioneers compact laser-driven radiation sources (LDRS). These dual-mode sources combine MeV X-rays and fast neutrons in a single system enabling real-time non-destructive inspection of complex or shielded materials. Our technology addresses critical challenges across nuclear waste storage contraband detection infrastructure inspection and medical isotope production.

We are a cross-disciplinary team of laser and plasma physicists engineers and AI experts building our first pilot facility in Biblis (Germany). Be part of shaping this deep-tech venture from the ground up!

Your mission is to directly enhance the performance of our laser-driven ion source a core component of the SourceLight platform. You will take ownership of a critical research area bridging the gap between advanced computational modeling and experimental reality. This role is a unique opportunity to drive a project from theoretical concept to hardware implementation making a direct impact on a technology that is going to redefine multiple industries.

What You Will Do :

Use simulations to improve ion acceleration : Lead the computational effort improve the laser plasma interaction by controlling the pre-plasma. Use Particle in cell and hydrodynamic simulations to increase laser-driven ion acceleration.

Apply Bayesian optimization : You will then apply machine learning and Bayesian methods to systematically discover the ideal parameters for peak performance.

Translate Simulation into Reality : Bridge the gap between theory and application. Translate your simulation findings into hardware specifications. You will work hand-in-hand with our engineering team to design and integrate your solutions.

Implement Intelligent Experimental Control : Go beyond simulation by integrating your machine learning algorithms directly into the experimental setup and drive the system performance.

Lead your project : Take full ownership of your research domain managing the project from end-to-end. You will set clear goals define timelines and communicate results that guide the companys technical roadmap.
