Part of a start-up where growth on a company and individual level is the default

The impact you will make

As a Wavefront Scientist , you will play a key role in the design, modeling, and validation of advanced laser beam transport systems for next-generation fusion drivers. Working at the interface between numerical simulation and laboratory experimentation, you will help ensure exceptional optical performance across high-energy laser systems.

You will develop and apply wave-optics simulation tools to predict beam propagation, aberrations, wavefront quality, and optical tolerances while actively validating simulation results through experimental measurements and diagnostics. Your work will directly contribute to the development of reliable, scalable laser architectures for fusion energy applications.

This role is ideal for candidates who combine strong computational and analytical skills with a passion for hands-on laboratory work and enjoy translating simulation insights into real-world optical system performance.

Your Responsibilities

Develop and maintain wavefront propagation and beam transport simulation models for high-power laser systems
Perform numerical analyses of optical aberrations, beam quality, diffraction effects, and system tolerances
Support the design and optimization of beam transport architectures, pulse compression systems, and frequency conversion stages
Plan and execute laboratory experiments to validate simulation predictions and investigate system performance
Configure and operate optical diagnostics for wavefront characterization, beam quality measurements, and alignment verification
Correlate experimental results with simulation outcomes to improve models and guide design decisions
Support commissioning, troubleshooting, and optimization of experimental beamlines and optical subsystems
Collaborate closely with optical, laser, mechanical, and systems engineers to translate requirements into practical solutions
Document simulation methods, experimental procedures, results, and design recommendations in a structured and traceable manner
Contribute to the continuous improvement of modeling capabilities, diagnostics, and laboratory workflows

Activities will initially be performed in the Greater Munich (DE) area, with occasional travel to research facilities worldwide.
