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.
What you bring
Master's degree or PhD in Physics, Optical Engineering, Laser Engineering, Photonics, or a related field

Proficiency in simulation tools and programming environments such as Python, MATLAB, Zemax, BeamXpert, CODE V, VirtualLab, or similar
Understanding of optical aberrations, wavefront sensing, adaptive optics, or beam quality characterization
Ability to connect simulation results with experimental observations and practical engineering decisions
Practical experience with optical alignment, laser operation, and laboratory troubleshooting
Strong analytical and problem-solving skills with a structured approach to technical challenges
Excellent communication skills and ability to work effectively in interdisciplinary teams
What sets you apart
Experience with high-power or ultrafast laser systems
Familiarity with deformable mirrors, adaptive optics, or phase retrieval techniques
Experience with pulse compression, nonlinear optics, or frequency conversion systems
Knowledge of GPU-based simulation methods or high-performance computing
Previous experience working in industrial R&D environments or large-scale scientific facilities
